EgyptAir 990 Speculation EgyptAir 990, and the cycle begins anew... It was a bomb, only a bomb could do it, and there are motives for a bomb and then it's not anybody's fault but the bad guys, whoever they are. And a very exciting story. It will be a missile when acknowledged it went down in W-15, an area of naval ships with missiles on board, must be cover up by US Navy. And even more exciting. It will be fuel tank explosion as soon as singed bits of wreckage are identified, must be God's fault with static electricity. Boring. Soon, the enemies of Egypt with motives for terrorist attack will be revealed. Soon the conspiracy angles of cover-up or assassination of important people on board will start to circulate. Soon the stories of heroic efforts and impacted emotions of those heroes recovering the wreckage will appear. Soon, the officials will be thanking everyone for their interest in aviation safety, and to not speculate and cause unnecessary grief, because they are doing the best they can and it will take years to have an answer and any internet stories just hampers the investigation. Soon, the manufacturer will be saying what a safe airplane it is and flying is much safer than driving. Soon, the government oversight agency will issue a few Airworthiness Directives, throw some blame around, and file a few lawsuits to show they are working hard to mollify the people. Soon, the condition of the inside of the engines, the radar plots, the wreckage debris pattern, the maintenance records, the weather and winds, the FDR, the CVR, the cargo manifest, photos of and access to the wreckage reconstruction, will all be classified, be hidden, be hard to access, and be distorted or cropped. And of course, days after event, it could be all those above and possibly many more. The confident keep thinking and modifying their hypotheses as facts arrive by the minute, while the scared and ignorant want to silence the conjecture and hide and wait and hope all the activity just goes away and things can get back to normal. The cycle continues... |

To Declare Or Not To Declare I enjoyed AVweb's Brainteasers quiz #22 on emergencies. I do have a question though. On a recent flight to Williamsburgh, VA (JGG) I was flying on an IFR flight plan and talking to Washington Center. A 172 came on asking for immediate vectors to the nearest airport as his engine was missing badly. The controller vectored him to Ahoskie and he was about 15 NM from Ahoskie when all this started. Center asked if he wanted to declare and emergency and he said "NO". When he got to within 6 NM he saw that he could not make the airport and indicated he was going to land on a nearby road. Again he was asked if he wanted to declare an emergency and again he declined. The controller had a Baron fly over the area to relay communications for him and apparently he landed alright. I was telling this story to a flight instructor friend of mine and indicated I was surprised he never declared an emergency. His response was that it would not have helped the situation at all since he was going to a uncontrolled field and ended up landing away from emergency facilities. What is your take on this? AVweb responds... It sure sounds like an emergency to me! I don't understand either the pilot's thinking or your flight instructor friend's thinking. There certainly are things that ATC can do to help, even if an aircraft is going to an uncontrolled field. Suppose that the aircraft hadn't landed all right; wouldn't the pilot want medical assistance sent immediately? If nobody on the ground witnessed the crash, such assistance might not come for a long time. There's no downside to declaring an emergency in such a situation; why not get all the help that you can get? --Irv Siegel, ATP/CFIA/I/ME, Brainteasers Editor |

ATC's Unsung Heroes What a fascinating discussion thread on ATC delays this is in AVweb. My experience of ATC and its problems is that of a frequent flyer with over 100,000 miles worldwide each year. I appreciate the prime function of ATC is safety and I am very tolerant of delays because the end result is I reach my destination alive! I have some friends working in ATC here in the UK and do have some understanding of the problems in the industry. I am also responsible for contracting a traffic spotting fixed wing service (Cessna 310) on behalf of the radio station I work for and I make sure there are seats on board for ATC staff any time they wish to come with us. But two major causes of delay astonish me in this high-tech world of communication. The first is the inability of the FAA to establish a realistic method of flow control given the technology that is now available. I was amazed to learn here on AVweb that when a congested airport like EWR has flow restriction operating for traffic heading towards it, all the sectors which have EWR bound traffic are not fully in the picture. The controller who explained his problem of having to hold or vector flights in his sector because he had a restriction of EWR traffic but the sectors feeding him had no restriction should never have been put in that position. Every aircraft with a flight plan should be registered in a central flow control computer on departure then all the constantly changing factors like weather and route congestion updated in real time so that each sector handling a flight is able to give it the optimum service so the sectors just outside the congested area do not get this problem. Seems simple enough to me and the costs would be recovered by virtual of the elimination of holding patterns at lower altitudes which invariably burn up more fuel. The second cause is the crazy scheduling by airlines of departures and arrivals in excess of runway and air route capacity. I was glad to read here that Northwest has finally realized that bad scheduling can be a major cause of delays and increased costs to airlines. I hope their cooperation with ATC bears fruit. Communication is the key to progress in this matter. Rather than looking for who to blame, all the major airlines should be looking for who to talk to and LISTEN to. By working it out together with ATC, the airlines would be able to rebuild their schedules to eliminate a large part of these delays. I have a great respect for the good work carried out by controllers who do their best in very difficult circumstances but always keep safety as the number one priority. Last month, Sept 29th, I was on CO 157 due out of EWR at 1650 local. After pushback at 1715 we were on the taxiway for TWO HOURS before we finally took off. I noticed on the departing runway that aircraft seemed to be restricted to one every six minutes. When I finally reached SFO I missed my connecting flight and had to take a hotel overnight at a cost of $240. Despite this annoyance, I was still grateful that the flight had reached SFO safely but was puzzled at what combination of circumstances had led to such a delay. EWR was working under clear visibility and SFO also had good weather. It could have been some form of equipment malfunction in the ATC system that led to such a restriction. The end product was a safe flight and that must always be the priority. For me there are two sets of unsung heroes of the ATC system. The first are the approach controllers at busy international airports who manage to filter complex traffic mixes into an orderly queue of arrivals. The knowledge of the capabilities of every aircraft type and required safe separations combined with communicating with pilots whose first language is not English is a task I do not envy. The second are the cool characters who handle multiple cross runway operations like at SFO looking after both departures and arrivals. I was on an NWA 747 going into SFO on the morning of October 16th when we had to execute a go round. I know it happens quite a bit at SFO but I do appreciate safety is always paramount -- so no big deal. I know I am in safe hands when ATC is operated at the sharp end by people who care with passion.
AVweb responds... Amen, John. It's the line controllers who make the system work, and hats off to them. I do think, however, that you underestimate the difficulty of the flow control problem. A case in point is San Francisco International Airport, where the runway configuration is such (parallel runways way too close for simultaneous instrument approaches) that the airport acceptance rate drops by half the moment the weather goes below what's required for visual approaches. During the winter, when the fog rolls in most nights, this precipitous drop in airport capacity happens nearly every day. The problem is that it's impossible to predict with any accuracy at all WHEN it will happen. Some nights, the airport fogs in by 3 p.m., while other nights it remains VMC until 3 a.m. The FAA's ATC System Command Center ("central flow") schedules east coast departures bound for SFO based on the acceptance rate it expects to be in effect some four hours in the future, yet nobody has a clue when that acceptance rate will suddenly drop by half. If the ATCSCC is pessimistic, aircraft wind up being needlessly held on the ground, while if they're optimistic, aircraft wind up stacked up in holding patterns. I'm sure there are similar situations at various other destinations around the country. Flow control is far from a trivial problem. There is also great controversy over the degree to which flow control should be centralized or decentralized. Regional Traffic Management Units (TMUs) at the various ARTCCs are more familiar with local airport, traffic and weather idiosyncrasies, and are able to react more rapidly to unexpected situations. On the other hand, they tend to make "suboptimal" decisions that may improve the situation in their own ARTCC's airspace but create massive backups in adjacent ARTCCs. The pendulum is presently swinging toward a stronger centralized function at the ATCSCC with less autonomy for the regional TMUs, but it's not at all clear that this is going to improve things. --Mike Busch, Editor-in-Chief |

The State Of U.S. ATC Is the need for more controllers simply understood and not stated, or do outsiders not understand how critical the shortage is? Atlanta Center, where I work, just set another record. Perhaps more revealing is this week's traffic count. Starting on Sunday the 24th and ending on Thursday the 28th, our daily count was 7578, 8251, 8615, 8929 and 9089. Consider that on Feb. 12, 1998 we set an all time record of 8590. Less than two years later that record is just an average weekday. But the big difference of course is that we have less controllers to handle the traffic. I don't know if the aviation industry understands what that means on a daily basis. It means that more and more ATC sectors are being worked by one person instead of two (or three). It means that when you need a second person to handle the traffic that they are late in getting there or they don't show up at all. That means there are more and more "unable" to requests and more "say again, I was on the landline." In other words, we get behind the power curve more often and stay behind longer. My major concern about this situation (of course) is the safety aspect. Safety is (and has been) degraded. It's as simple as two controllers working a sector are safer than one working alone. But if I can't get people excited about that, I will gladly take the opportunity to push for two controllers per position for efficiency's sake. And the real kicker is....it takes FIVE YEARS to make a controller. We're finally starting to get some trainees. But it won't help for YEARS! Any improvement in ATC is going to require more controllers. Do people in the industry understand this????? |

EVAC-U8 Smoke Hood Can the EVAC-U8 smoke hood recommended by Mike Busch's review article be worn by children? Which would you recommend for children and infants? AVweb responds... The EVAC-U8 hood itself will work for a child, since it has an adjustable drawstring. However, the mouthpiece might be uncomfortably large for a small child to fit inside his or her mouth, in which case it might have to be used externally, something like the mouthpiece on a diver's snorkel. It might also be difficult psychologically to persuade a very small child to wear a smoke hood and to breathe through the mouthpiece, particularly in the trying circumstances that would normally be present when a smoke hood was needed. Using a smoke hood is something of an unnatural act, if you know what I mean. It's not easy to get an infant or small child to use a headset or an oxygen mask, much less a smoke hood. I'm unaware of any smoke hoods designed specifically for infants and children, although that doesn't mean none exists. I think the theory is that the smoke hood keeps the adult from becoming incapacitated long enough for the adult to carry the infant or child to a safe environment. --Mike Busch, Editor-in-Chief |

The State Of U.S. ATC Absent a major recession, the demand on our nation's airspace infrastructure will push the ATC system even farther past its original safety design limits. And worse yet, with more errors and delays comes the frustration and the pressure to do something, anything. Sadly, actions taken under this type of pressure have, and will continue to lead to the inevitable -- catastrophe. It is clear to me that those responsible for ATC system oversight (DOT, GAO, Congress, airlines, etc.) must stop telling FAA what they are doing wrong, and begin telling them what to do right. The real problem with the ATC system is simple -- FAA's complete lack of vision. From MLS to AAS, and now to GPS, ADS-B and NAS 4.0, FAA continues to prove that its vision is seriously flawed or nonexistent. They continue to spend billions ($27 Billion since 1982) on R&D and unproven technologies in an ill-fated attempt to squeeze a few more years out of the current ATC process, yet we are losing the one thing that we cannot afford to lose -- time In the interests of safety, it is incumbent on the airlines and others to look outside FAA for a different vision of how to fix the chronic delays, operational errors and equipment problems inherent in our 40-year-old ATC system. As I have stated in the past, I have the vision to fix the ATC problem within three years while increasing safety and capacity for less than $1 Billion. But without a change of direction by FAA, it won't happen. FAA wins; the airlines, the flying public and the taxpayers lose.

Amateur Jumper?
I don't know if you quoted this directly from some source, or pieced it together, but unless the word "amateur" is a direct quote, I'm surprised you'd let that slip into AVweb. I don't see that as any different than if you described a pilot other than airline as being an "amateur pilot" (such as the "common" media is so likely to do). Having sky-dived myself, and having a friend who's an owner of the largest DZ in Colorado, I would think that they would rather not be referred to as amateur jumpers... If that was a direct quote...never mind. AVweb responds... Marc, the word "amateur" came directly from our Russian "source" on the story, and was used to denote the fact Kiryukchin was not an experienced jumper. Following is the what we wrote in our expanded coverage that appears in AVweb NewsWire:
Thanks for writing, and thanks for reading AVweb. --Liz Swaine, News Writer |

Payne Stewart Learjet Crash I would be interested in hearing John Deakin's opinion on the recent Lear 35 accident involving Payne Stewart. I know at this point he would be speculating, but we will take that into account. My own speculation. based on 25 years with USAir, is this: 1. Do most business jet Captains preflight their oxygen system prior to departure and do they do it correctly? Having an explosive decompression happens so seldom that most pilots do not really give it serious consideration therefore perhaps the Ox system does not get checked properly! 2. Even with the airlines I observed many pilots that simply toggled the Ox system to the 100% level and then flipped the switch that let the Ox flow a bit. Never even try on the mask. Might mess up the hairdo. I have found on a few occasions, after pulling the mask down to put it on that it was "Disconnected". I have found valves in the manifold set to the off position. (Previous maintenance was done on system.) 3. There should have been enough time for the pilot to grab the mask as I am sure he was taught, however I suspect (and here I go speculating) that there was something wrong with the oxygen system. It did not work. Even if the cabin pax had gotten to the masks in time, their supply of oxygen was probably from the same bottle. The oxygen system in aircraft that fly in the Flight levels, especially above 25000', have been taken too lightly. Maybe now this will change. I cringe when I think about all those guys flying at 25000 to 30000 with nothing but chemical canisters. In the early days of Malibu sales even the canisters were an extra-cost option that some pilots did not opt for. Okay, John, what's your take on all this?? Thanks! P.S. Makes one think twice about going for a ride on the new Lear Model 60 which I think is certified for FL510! AVweb responds... All your own remarks are very much on point, of course. Do most bizjet captains preflight their O2 systems correctly? I doubt it, but I don't know. Airline O2 system preflights minimal? Guilty as charged: ON, 100%, EMERG, and listen for the hiss of O2 from the mask just over my head. I don't do it for my hairdo, but you'd be surprised how many cases of cold and flu I used to get, and how few now. But I usually pick up an airplane enroute, and the Japanese check those things faithfully and correctly, EVERY time, so I "make an assumption." Of course, a 747 will also lose cabin pressure a lot more slowly than a Lear, so I'm pretty casual about putting it on inflight. Valves set to the OFF position? JAL's policy used to be to turn the master valve off after EVERY flight, even a quick turn. FINALLY got 'em to change that, now it's turned off only when arriving at home base. Dunno why they do that, either. O2 systems taken too lightly? Maybe. Except for the really careless, I'm not convinced the regs or procedures really need to change for one crash, as dramatic as it was. To my knowledge, that's the ONLY case on record in something like 40 years. Let's not panic. Most of the fuss is over the loss of Payne Stewart, but he had no more value to me than you, or even Mike Busch does. <grin> I'm interested only on the crash, and the reasons for it, not who it killed. Cringe at chemical canisters? I dunno a lot about them, but a lot of transport use 'em (for pax). Good enough for backup, I think. I'd rather have O2, thank you very much. But it's not all that bad, because even with a blowout at 250, you can probably get down without losing the airplane, if you GO NOW. Everest has been climbed without O2, remember. My fear would be getting up over weather (ice), and needing to get down. I'd rather have full O2 for all, and be able to stay up there. Lear 60 at FL510? Some bizjets will go to 550, I think. Concorde goes to 600. It's a calculated risk, as is all of life, and the numbers look pretty favorable, to me. --John Deakin, Columnist, Pelican's Perch |

Payne Stewart Learjet Crash Regarding the tragic crash of Payne Stewart's plane, I wonder if I could ask a couple of questions about depressurization? If at that altitude -- about 39,000 feet -- sudden depressurization occurs and there are only 5 to 10 seconds to put on an oxygen mask, if you were able to get the mask on, wouldn't there be a pressure conflict from what your body is breathing to the outside pressure which is nil ? Is that why they have an emergency decent procedure? What psi is the oxygen going into your body through the system? Also, shouldn't one flight crew member always be on oxygen at that altitude for safety? What backup systems are there on commercial aircraft? Does the flight crew get warnings that depressurization might occur? AVweb responds... I think it's unlikely that the Learjet suffered "sudden" (i.e., explosive) depressurization, since apparently the military aircraft that observed the aircraft at close range observed no gaping holes in the structure, blown-out windows, etc. If an outflow valve stuck open, for example, the cabin would depressurize gradually over a period of perhaps 10 to 30 seconds, perhaps longer. In a sudden depressurization incident, the cabin atmosphere becomes frigid and foggy (as moisture condenses), while the occupants involuntarily expel "odorized" air through all of the obvious bodily orifices. The equalization of bodily pressure takes just a second or two, after which there's no problem breathing through an oxygen mask. (I've experienced this firsthand in a military altitude chamber.) All pressurized aircraft I know of are equipped with a red warning light that alerts the crew any time the cabin pressure altitude rises above 10,000 feet. They also have a cabin altitude gauge and a cabin differential pressure gauge. I am not certain, but I would guess that on a Learjet the cabin pressure warning would also cause a master caution light and horn. At Flight Level 410 or below, there is no requirement that flight crew members wear oxygen masks so long as both pilots are at their station. If one pilot leaves the flight deck, the other pilot is required to don his oxygen mask until the first crewmember returns to his seat. Loss of pressurization is not an unusual occurrence. Crews routinely train for this situation during annual recurrent simulator training. There is normally adequate time for the flight crewmembers to put on their quick-don oxygen masks, radio a mayday call to ATC, and start an emergency descent. For these reasons, I have to believe that this accident involved something more than simple loss of pressurization. Perhaps the emergency oxygen system failed, or the crew was overcome by carbon monoxide or some other incapacitating factor. Given the condition of the wreckage and the fact that the Cockpit Voice Recorder is unlikely to reveal anything useful (because it contains only the last 30 minutes before impact, and the crew incapacitation apparently occurred hours earlier), it is quite possible that a probable cause for this crash may never be determined. --Mike Busch, Editor-in-Chief |

Payne Stewart Learjet Crash I just wanted to pass along a message that I think is important for everyone. The papers all seem to be saying depressurization. True, that's what it looks like. Everything points to it. I think that AVweb has a chance to really point out some facts here. As we are all pro-aviation, the recent rash of celebrity crashes seem a pending doom. People will remember John Denver, JFK Jr, and Payne Stewart and point to GA as the problem. Some will point out the recent helicopter accident involving Harrison Ford, or stunt pilot Wayne Handley. All are minor in the grand scheme of things. I think that the press misses out on the fact that quick-donning oxygen masks are required at those flight altitudes. In addition, everyone is using FAA numbers for useful time post decompression. They are saying 10 to 15 seconds. These are best-case scenarios. Most likely it's 8 to 10 seconds. Without a quick-donning mask on, there is little chance of a crew being able to interpret what happened, grabbing the mask, and pulling the oxygen flow valve prior to hypoxia. FAR 91.211 provides the clear loophole for not wearing a mask:
Since there were two pilots, they need not have the quick-donning mask on since they were under FL410. Who knows, speculating like the press is, maybe the crew was not familiar with the location of the masks, the pressure loss caused them to lose their breath, and within seconds they were suffering from hypoxia. Who knows. We probably will never know the exact cause after the horrific crash that ensued. I don't believe many pilots have been able to experience the effects of high altitude. I've gone through an FAA-approved course once before, and am already in the process of planning for an additional course in the January time frame at Edwards Air Force Base. The Air Force, along with the FAA, have this course available to all pilots. Why don't commercial pilots use it as well? It includes ground school, decompression simulation in an Air Force altitude chamber tank and exercises to show the effects of hypoxia. VERY, and I stress, VERY educational. When you can't write down your own first name on a simple question test because you can't comprehend the question/don't understand what your name is, it's kind of spooky. The FAA leaves a nice note on our licenses, "Safety is no accident, it must be planned." I'm planning for the future, forcing myself to experience it first hand. I'm practicing, getting myself ready, is the rest of the community ready? If not, WHY NOT? Happy flying all. Lets keep it safe. San Jose Police (San Jose, CA) lost a fine pilot on Monday when his five year old Boeing police helicopter crashed on a maintenance check-out flight. The crash killed both the pilot and the maintenance worker. A very sad loss for the area. (FYI, the crash occurred literally just blocks from where I resided). AVweb responds... Curtis, I couldn't agree with you more about the importance of high-altitude physiological training. Like you, I've been through the course and altitude chamber "ride" that is offered at many military facilities as well as at the FAA's own facility in Oklahoma City. I strongly recommend it to any pilot who does flight-level flying. On the other hand, I have a hard time accepting your suggestion that the Learjet pilots might not have known where to find their quick-don masks, or how to put them on in time to remain conscious in the face of an alleged depressurization. These days, nobody flies an aircraft like a Learjet without at least annual recurrent sim training at a facility like FlightSafety or Simuflite (at least if they want to be covered by aircraft insurance). Loss of cabin pressure is a routine part of such training. It's hard to imagine that the flight crew wouldn't have know precisely what to do in the face of a depressurization situation, because they undoubtedly practiced it time after time in the sim. Furthermore, initial reports seem to indicate that the military aircraft that formed up with the incommunicado Learjet didn't see any gaping holes in the fuselage, blown out windows, open doors, or the like. This suggests to me that any depressurization that might have occurred was probably not the sort of "explosive decompression" that you and I both experienced in the altitude chamber, but a somewhat slower process that should have given the crew ample time to react. That's why I suspect there's more to this crash than a simple case of loss of cabin pressure. In my experience, pressurization problems are not all that uncommon. When they occur at high altitude, they're certainly an emergency situation requiring supplemental oxygen and a rapid descent. But they're generally more annoying than life-threatening. Something about this accident was different. I can only hope that NTSB investigators found enough left in that South Dakota crater to figure out what it was. --Mike Busch, Editor-in-Chief |

Contract Towers I thought I'd throw in my two cents' worth about the contract tower program. My background: I am a former Marine Corps airfield services officer (aircraft fire-rescue and airfield matting/lighting/arresting gear). I've been an airport fire chief at three military airfields and one civilian airport, and I'm currently an airport director, so I've had the pleasure of dealing with many air traffic control folks on various issues. Also, I was the Safety Chief (fire/rescue, operations, and law enforcement) at the airport in Albany, Georgia, when the tower went contract (it had previously been FAA-manned). Truth be told, I viewed the idea with a rather jaundiced eye (I'm from Missouri -- show me!). I knew nothing about the track record of contract towers at other airports and I was quite skeptical about having non-FAA people working with my Safety Officers, especially when an aircraft emergency or mishap was in progress. But I'm now a believer that contract controllers can be are just as competent as FAA controllers (hell, pretty much all of them are FAA or military trained). The ones at Albany certainly were. I could not tell any difference in the proficiency between either group (as it should be). And the contract controllers were a LOT friendlier and easier to work with than the FAA controllers were at times. One of the latter, in particular, was a real pain. He had terrific mood swings and regularly acted as though pilots passing through his airspace and vehicles on his AOA were an imposition. He was well-known throughout the local flying community, and the pilots (and my Safety Officers) had little use for him. Everyone could tell the difference when the FAA controllers left and the contract controllers came in, and our traffic numbers started to go back up. And I regularly heard favorable comments about the contract controllers from the pilots I associated with at the airport and EAA meetings. Why the difference? There's one big incentive for the contract controllers -- they know that if the airport doesn't like the service they've been getting, it will let the FAA know loud and clear. It doesn't matter to the airport which company comes in and works, as long as they do a good job. On the other hand, the FAA controllers have the union and government work rules to protect them. They have to be competent -- but they don't have to be customer-friendly. A further incentive -- the benefit/cost (B/C) ratio for a number of the airports with contract towers hovers close to 1.0, which is the break-even point. If the traffic numbers go down, and the B/C goes below 1.0, the airport has to pay the difference. In Albany's case, while the FAA controllers were there, the airport received a two-year letter notifying us that the B/C was below 1.0 and if it didn't go up, the tower would have to close (this was before the FAA instituted the cost-sharing program). After the contract controllers came on board, the numbers started to rise, we saw an increase in activity, and the B/C went back up over 1.0. Was it entirely due to the friendlier attitudes of the contract controllers? They certainly played a major role, if the comments from my fellow pilots and EAA members were any indication. There's a heck of a difference between an abrupt "Contact Center, xxx.x," and "Contact center, xxx.x, y'all come back now, y'hear?" I can hear the anvil chorus now -- "That's anecdotal evidence, don't judge all FAA controllers and contract controllers by what you experienced at one airport." True enough. However, almost all of the other airport directors I've talked to (and I've talked to a BUNCH of them) have had very favorable experiences with the contract controllers. And if the contract controllers were unsafe, why would the FAA stick its neck out by giving them passing grades on their evaluations? I know that the Albany contract controllers did just fine in their evaluations -- it didn't appear to me that the Feds fudged the evaluations or cut any slack to the contract folks, and that's as it should be. If there is a problem with the program, it's in the staffing (as has been pointed out by NATCA). The FAA does indeed need to make the contractors toe the line to meet staffing standards, and we (the airports) will help them monitor the contractors if they give us half a chance. When we asked the Feds to give us the necessary information to do just that, they said they couldn't, as that information was part of each contractor's bid, and giving it out would compromise the confidentiality of their bids. But they did say they would look for ways to help us keep tabs on the contractors' staffing and adherence to the contract. In summary: I went from being a hard-nosed skeptic to an eager believer on the subject of contracting Level 1 towers. I don't know enough about contracting out anything above that level, I'll leave that debate to those who have a dog in that fight. And I'll be happy to listen to arguments against the contract towers. But if those arguments focus don't focus heavily on the safety and customer service aspects, it'll be tough to get me to change my mind, based on my experience and the comments I've heard from other airport folks.

AVweb Auctions Well I really liked your new AVweb Auction site until just the other day ... when my wife discovered it. Although an avid pilot, she has not been too interested in the Internet until she was peeking over my shoulder a few days ago watching me review all the neat stuff for sale. So thanks a lot, AVweb! My wife will now be the finest-outfitted pilot at FFZ. Meanwhile, I'm still flying with my ten-year-old headset, and I may not be able to afford avgas much longer. Guess I'll be lookin' for that second job soon. Seriously, it's great! Keep it up. AVweb responds... If push comes to shove, Curt, you can always try auctioning off that old headset.

FAA Crackdown on Duty Time Limits For several months there have been rumors floating about the industry saying that the FAA would soon be changing the Part 121 & Part 135 duty time and flight time limits, or at least more closely monitoring and enforcing compliance with existing limits. Has there been any definitive announcement of exactly what, when, and how this is going to happen? If so, I trust that AVweb News will be among the first to let us know. AVweb responds... Jim, it's not just rumor. We reported some time ago that Administrator Garvey had gone on record as saying that the FAA was going to start holding commercial operators' feet to the fire with regard to compliance with duty time and flight time limits. So far, we've not heard of any notable certificate actions or civil penalties, but if we do, we'll certainly let you know in AVweb News. --Mike Busch, Editor-in-Chief |

Qantas Accident History Regarding your "QANTAS DECISION PAR FOR THE COURSE" story and the comment that "Qantas has never lost an aircraft and isn't about to let this bogey be the first" ... The truth is that Qantas has had over 60 aircraft accidents since WW2 including at least 15 where the aircraft was a total loss, five with fatalities and at least four with no survivors. My source? Wings to the World -- the story of Qantas from 1945 to 1966 by Sir Hudson Fysh. The authors credentials are excellent. Not only was he one of the founders of QF but Chairman of the Board (CEO) for many years until his retirement in 1966. Appendix 8 is titled Accidents to Qantas aircraft 1946-66 Excluding accidents to light aircraft (the capital E is in the official title). This lists most of the heavy aircraft accidents however the text and photographs include several more including one with no survivors. One should remember that although QF has not had a fatal since January 1970 it must be remembered that QF is a very small airline -- just 44 aircraft before the merger with Australian about 5 years ago. While United has had four fatal accidents since 1970 it has operated over 15 million flights in that period giving it a fatal accident rate of less than 1 per 3.75 million flights. QF has operated less than 1.1 million flights in the same period. Assuming the same rate of operations this means QF needs just one fatal before September 2068 to have a worse fatal accident rate than United. (The math is 3.75 / 1.1 x 29 plus 1970 = 2068.86.) A review of the Bureau of Air Safety Investigation incident reports over the past couple of years shows Qantas shows up far too often -- especially in near mid-air incidents and several near CFIT's recently. AVweb responds... Okay, then, how about if we said, "Qantas has never lost a jet"? (Boy, you just can't get away with anything around here, can you?) --Mike Busch, Editor-in-Chief |

Recycle Your Transponder? Can you tell me what is meant by "recycling your transponder"? Do you turn it off, turn it to standby, or what? AVweb responds... Funny you should ask, Charles. "Recyle your transponder" is one of those universally-used items of controller phraseology whose meaning nobody really knows, and is nowhere defined so far as I can determine. When a controller asks you to recycle your transponder, what he's really saying is, "I'm not receiving your transponder properly, so if there's anything you can do at your end to solve the problem, please do it." When I'm asked to recycle my transponder, I turn my transponder to STBY, reset each of the four code digits (to make sure that the code is entered correctly and the code switches are making good contact), and then return the transponder to "ALT" (Mode A/C). But that's just me. I bet if you asked 100 pilots, you'd get 98 different answers. And if you asked most non-pilot controllers how to recycle a transponder, you'd just get a blank stare. --Mike Busch, Editor-in-Chief |

Passive vs. Active Headsets As a student and low-budget pilot, renting small planes to fly with, it would be nice to have my own headset. Sometimes the ones in the planes I rent are really awful. So it would be very interesting to read a test of good quality passive headsets in AVweb. After all, the passive ones are quite a bit cheaper than active ones. And as Mike Busch stated in his review of the latest LightSPEED active headset, most active headsets do not improve the silencing capabilities that much in active headsets compared to passive ones, at least not in headsets up to $400. I figure, many guys like me rather want passive quality headsets, than low end active ones. They will probably serve us longer and take the beating of being transported in a bag, being moved from one rental plane to another. Now, I havenīt personally ever had the opportunity to try out an active headset. Iīve been thinking of one thing though. Isnīt there a risk with the REALLY GOOD active headsets, that you do not get good enough acoustic feedback from the engine sound? Personally I like to listen to the engine to be sure it is running the way it should. AVweb responds... I did not suggest that active headsets "do not improve the silencing capabilities that much" compared to passive headsets. Quite the opposite: I don't believe that any pilot who has flown with a decent active headset (even an inexpensive one like the under-$300 LightSPEED 15K) would ever be satisfied going back to a passive headset. As to whether active headsets attenuate engine sounds to the point of creating a safety hazard, the answer is absolutely not. To the contrary, an active headset makes it far easier to hear abnormal sounds of any kind. Active noise cancellation attenuates the extremely low-frequency sounds of exhaust and prop pulses, making it far easier to hear other sounds that would otherwise be masked. With active headsets selling in the under-$300 range, I feel that it's hard to justify the purchase of a passive headset any more. --Mike Busch, Editor-in-Chief |

TCM VAR Crankshafts Prices I am overhauling my IO520BA. As per the AD, I have to install a new VAR crankshaft. Unfortunately, because of the recent AD on the crankshafts, there is a 90-day waiting period. This is not the problem. It appears as though Continental has increased the price of their crankshaft from $2,600 to $5,000 dollars. I realize that they set their price at $2,600 to make the necessary change not hurt so bad. However, even with the shortage, is there any way to get them to reduce the price of a new crank back to the $2,600 dollar range? Note, I am not complaining about the new crankshaft. I just don't like to feel that the shortage entitles them to stick it to us. AVweb responds... So far, we've been unable to confirm whether or not TCM has increased the price of these crankshafts. We'll continue to follow up on this issue and report our findings in AVweb News. --Mike Busch, Editor-in-Chief |

Fruits and Vegetables Your choice of fruit in the headline "NATA Squeezes an FAA Lemon" struck me as curious. Given that you quote NATA vice-president Andrew Cebula, and that "cebula" is Polish for "onion," perhaps you might have considered something along the lines of "Repair Stations in a Pickle." Brings tears to your eyes, doesn't it?

EAA and Ultralight Exemptions There are a lot of rules and regulations in aviation. There are way too many. But there are never enough, because situations change. Once you have a rule, it is easy for people to see that there must be exceptions or the rules will tend to make matters worse. Consider Part 103, the Ultralight Regs. The original idea was simple and philosophically sound: You can, under 103, do many things with no regulation, but only if you fly a single place aircraft and put no one else at risk. The last part is addressed by limiting operations to uninhabited areas. Over time, enterprising people turned the UL into something close to a small airplane. They weren't hang-gliders, and the opportunities to 'teach yourself' were getting into the realm of pure lunacy. It would be a little like going out and renting a 152 to teach yourself. If I wanted to teach myself, I'd certainly rather rent than own. But, the fundamental reality of Part 103 remained that of a single place airplane. The resolution came by coaxing the FAA to adopt certain training exemptions to Part 103. Now there are Ultralight Trainers with two seats, plus some additional fuel and weight. There are UL instructors who can haul around a student who, we are told, is not a 'passenger'. EAA faces a somewhat similar problem. Most experimentals are 'different' from the Cessnas that people train in and rent or own. In some cases, the high performance end, the differences can be significant-- risky. There may be certificated aircraft that are similar, but as you combine elements like high performance and tailwheel, you may not get 'close enough'. You may not get the person to do enough training, anyway. Obvious solution: if you want to buy a high performance experimental, why not train in the same model? Because aircraft with that category of airworthiness certificate are not supposed to be used for commercial purposes. For the most part, this limitation makes sense, given the limited purpose that cert provides. If you want training you may still find dealers, manufacturers, or other owners who will help without 'compensation', at least directly. But clearly, letting people use private aircraft, experimentals, for training, would be easier if you could pay them. It might work, may work, but it probably will be messy. The UL exemption for two place immediately created a lot of flight instructors and a lot of 'trainers'. It seems obvious that there have been abuses. The FAA has seethed. Aside from this, the exemption process creates a lot of inequities and difficulties. Two people could build exactly the same aircraft, a two place. One could register it as a homebuilt experimental. This airplane would have an airworthiness cert. The other could register it as a UL trainer, in which case he wouldn't deal with the FAA. Rather, he would go to one of the UL orgs and get an exemption, which he would carry around. Because there are two paths, several differences are possible along the way. The homebuilder has to actually do the building. The UL 'instructor' does not. He can have a dealer or the kid next door build it. In a year, both the owners might decide to sell their aircraft. Assuming the construction was similar, these aircraft are physically the same. But one will have an airworthiness certificate, so any certificated pilot might fly it. The other will qualify for an exemption as a two place UL, but only for someone with an instructor rating, a UL instructor. If the aircraft with an airworthiness cert was sold to a UL instructor, that instructor would not be able to instruct in that aircraft because it had that piece of paper attached to it. He can't have a UL if the aircraft has an airworthiness certificate, though he might choose to un-certificate it and get the exemption. It would be difficult to go from an exempted trainer to a homebuilt experimental, under the regs. The UL training programs have been quite successful. No one is arguing that. The only question is whether the process of regulation through exemption created rules that did not fit in terribly well with other rules. Anyone who studies the history of UL's will find that many of the regs that really affect the sport are actually exemptions. The primary UL org, the US Ultralight Association, has been quite adept in advancing the sport through exemptions. Given the high level of competition and tension between USUA and EAA, it is interesting to see EAA moving down their sister orgs path. USUA basically maxed out the exemption process, by trying to pile exemptions on top of each other. The Malone petition attempted to expand the privileges of those who trained under the training exemption, by giving the students another exemption for larger, or two place, aircraft. The FAA said "No". In part, this led to the formation of an ARAC committee to produce a new set of regs. That is embodied in Sport Pilot, a simplified airman certificate. Sport Pilot is a very hard sell because the exemption process and the abuses, have made people impatient with the cumbersome process of making 'real' regs. The exemption can be instant gratification. The exemption process prevents nasty comprehensive examinations of the regs. It protects what the orgs have, while offering a chance for more. Some regs may be over TBO. In terms of EAA's request for an exemption to allow commercial use of experimentals for 'type' training, it certainly sounds good on the surface. But you do have to wonder how people may try to abuse this. What's going to prevent 'regular' training from taking place in experimentals? If experimentals are acceptable for one type of training, why not for another, anyway? The FAA may end up appearing to say "Well, they're not safe enough to train in, unless not training in them is more unsafe." Which begs the question: "ARE they safe to train in, and under what circumstances?" EAA has almost complete control of the experimental aircraft scene. They have been heavily involved with the FAA. They also have a clear agenda -- high performance. EAA should certainly have to defend its position, at least relative to other interests. It is far from clear that the exemption process allows this to happen. If EAA is granted an exemption, there may be abuses and there may be requests for more exemptions. The issue that EAA is addressing really suggests that where they have taken the sport has outstripped the original regs. The regulator should ask if this solution is a 'Band-aid'. EAA wants to push for high performance. That probably suggests other issues, in addition to flight training, deserve a second look. Is the aircraft certification adequate for homebuilt turbines? Flight training is part of 'safety' and that makes it a good issue, tactically. The tendency has been to try to expand the exemptions, away from the easily justified, into areas where it would be 'convenient'. But the 'exempted' use can be very hard to define. It also can create identical aircraft with different sets of paper attached to them, and pilots with different kinds of certifications, medical requirements, etc, doing exactly the same thing. If the exemption process is sloppy, that creates other hazards. The only time the regs really matter is when things go very wrong and the legal liability is piling up. At this point, the lawyers and insurance companies will certainly become familiar with the letter of the law or regulation. If the regulations are not comprehensive, if they don't reflect the evolution of the sport, it is the little guy who will pay, but maybe only in that extreme case. You can go to many airports and see the heavily regulated GA aircraft with regular airworthiness certificates. Next to them are the far less heavily regulated experimentals. Next to them may be completely unregulated UL's. There certainly are tensions here, and there isn't a lot of middle ground. The FAA hasn't devoted many resources to the non-commercial side of aviation. It's easy to see the abuses and the problem areas. The FAA probably needs a regulatory process that is more flexible than regular rulemaking, without using the 'emergency' exemption process. You have to hope that the regulators and the leaders are taking a fairly long term view of things. The 'exemption' process has a history of being a short term solution that left problems in its wake, at least as regards Part 103 and Ultralights. |

FAA Airman Database Why has it been such a long time since you updated AVweb's airman database? AVweb responds... As of May 1998, the FAA Chief Counsel ruled that the FAA could no longer make the airman database available as they had for decades before, saying that doing so violated the Privacy Act. The FAA budget reauthorization bill currently in conference committee on Capitol Hill is expected to contain language that directs the FAA to resume making this information available, with appropriate "opt-out" safeguards designed to protect the privacy of airmen who do not want their address made public. We are hopeful that the FAA will start making airman data available once again after the first of the year.

C(cold)-130 In your newswire article on the C-130 that landed to retrieve Jerri Nielsen you stated:
A reference that I have gives the ceiling of the C-130 as 41,000'. I'm not sure if your "58 degrees" above is Celsius or Fahrenheit, but a standard temperature and lapse rate would put the temperature at 41,000' at -64 degrees C (-84.5 degrees F). Today's actual temperature over Indianapolis at 41,000' is -51 degrees C (-59 degrees F). Why would the hydraulic fluid "become sluggish or fail" on the ground at "58 degrees" but not fail in the air at much lower standard temperatures? As you point out, the engines were running. AVweb responds... Damn good question, Greg. Our story was based on a NASA press release, and we took the accuracy of the information for granted. We'll try to find an answer. --Mike Busch, Editor-in-Chief |

AirSport Altitude Alerters AVweb continuously advertises the AirSport Altitude Alerter as the only "low cost" device which reads your transponder's Mode C. Although I'm not a special fan of Electronics International, they have a device I've installed in my plane called the ASC-5 Super Clock. It reads Mode C, OAT, and has timers and a clock. It computes density altitude and can display degrees F or C and time in Zulu and local. It alarms at preset intervals, at an expired time and at climb, cruise and descent altitudes. I paid somewhat under $500 for it. I think your repeating AirSport's claim is misleading. AVweb responds... Frank, I'm very familiar with both the AirSport alerters and the Electronics International unit you have in your airplane. In my judgment, the advertising claims for the AirSport are accurate. Let me explain why. Your EI ASC-5 (like most low-cost altitude alerters) is hard-wired to the output of your altitude digitizer, just as your transponder is. In contrast, the AirSport alerters actually have a 1090 MHz receiver which receives and decodes the transmissions of your transponder in response to ATCRBS interrogations. To illustrate the difference: If you turn your transponder to standby, your EI ASC-5 will continue to display the pressure altitude output by your encoder. It has no idea whether or not your transponder is transmitting to ATC. On the other hand, the AirSport encoder will stop reporting altitude and display a message indicating that your transponder is not transmitting. Most other altitude alterters (and your EI ASC-5) have to be hard-wired into the aircraft avionics system. The AirSport is completely independent of the aircraft wiring, and requires no connection whatsoever, making it ideal for renter-pilots. --Mike Busch, Editor-in-Chief |

ASDI As Poor Man's TCAS? Couldn't I use FE Personal Edition as "quasi radar" in the airplane itself, if I find a way to connect a laptop to a data cable and that to a cell phone and dial in to an internet service provider, and then use FE? Do cell phones work up there? How bad is the update cycle really? You mention up to four minutes. Is it really that bad regularly? AVweb responds... Nice try, Andreas. That thought occurred to me, too. But there are a couple of problems that make the idea infeasible. Airborne use of cellphones is barred by the FCC, who can slap you with a big fine and imprisonment for using a cellphone aloft. Modern digital (PCS) phones don't seem to work worth a darn at altitude, anyway. Even if that weren't a problem, the FAA updates most ASDI aircraft positions only once every four minutes, which is an eternity if you're trying to use it for collision avoidance. This isn't a throughput limit, either. Even in the middle of the night, when there's hardly any traffic, the FAA only updates each aircraft about every four minutes in most areas. To add insult to injury, the ASDI feed does not include VFR aircraft. A collision avoidance solution using ATC-provided traffic position data would certainly be vastly cheaper than TCAS. However, the present ASDI feed is simply not suitable for such an application, even if we had a cost-effective method of uplinking it to aircraft. It doesn't include non-IFR aircraft, and the update rate is simply way too slow. The FAA didn't design ASD for this purpose, and clearly does not want the ASDI feed to be used in such a fashion. --Mike Busch, Editor-in-Chief |

Cellphone Use In Aircraft May Not Be Dangerous The letters and comments on use of cellphones in aircraft have made the point very well: The prohibition comes from the FCC, not FAA, and is due to the way the cellular system works. A cellphone is supposed to hit a nearby site with a stronger signal, whereupon that site uses its control channel to alter the phone's transmit power to a level that will not cause unnecessary interference with other cellular sites. But from altitude the phone hits too many sites, the control channels cannot cope, thus the prohibition. Fair enough, there are technical reasons not to use a cellphone aloft. But does a cellphone ENDANGER the operation of the aircraft? What about a GPS, or a laptop, or a CD player? That is a very different problem involving FAA rather than FCC. In my opinion, if an aircraft system can be upset by a cellphone, that aircraft system can be upset by a great many signal sources and is of very questionable safety in the first place. You don't have to be an electrical engineer to understand the relationship. Things with tiny batteries can only produce tiny signals. Things with bigger batteries can produce more. And things with big thick power lines coming in can produce a LOT more! If an aircraft system responds to a one-watt cellphone, think what it might do with a million watt TV station. What about all those high powered RF induction heaters and EDM machines and electroplaters and other electrical processes being used in the industrial area under the approach? Today our world is full of signal sources. Most of them are far more powerful than a little cellphone, and many are less regulated. If that Gameboy in coach class is a hazard to flight, the only sane answer is to ground that aircraft until better systems are installed. And if better systems are not available (which in most cases they are not), then we had better be asking FAA some serious questions. Safety of flight is far too important to trust it to some kid playing with his toy. On the other hand, if the FAA has been doing it's job properly and the certified aircraft systems are safe, then FAA ought to have faith in them and quit telling everyone to turn off their gadgets below 10,000 feet.

Carbon Monoxide Detectors A brief note on my experience with the AIM SAS-696D carbon monoxide detector recommended by Mike Busch in his AVweb review article. My flight instructor brought his detector to the airport to demo it in my Cessna 150. We took off, climbed, cruised, turned cabin heat and air off and on, and landed. All of this with a detector reading of zero. At this point, I was beginning to question the utility of the detector. As we taxied out behind another aircraft for a second takeoff, the reading rose to 15. We departed behind the preceding aircraft and the reading went to 25. As we turned to a heading different from the lead aircraft, the reading slowly decreased to zero and remained there for the remainder of our flight. The sensitivity to CO entering my cockpit from another aircraft convinced me to buy my own unit for the plane and two more for my family. Thanks for recommending a GREAT product. AVweb responds... Thanks for your feedback, John. --Mike Busch, Editor-in-Chief |

Gondola INCIDENT? Your newsletter is a great service to the aviation community, but qualifying the event of the gondola as an "incident" means you do not consider the death of many civilians as a tragedy. I hope this was a mistyped word. AVweb responds... We certainly didn't intend to convey a lack of sympathy for the gondola victims. I'm a pilot (as are the rest of the members of the AVweb staff) and I assure you that I don't take accident reports lightly. Rather, in this case, we used the word only in its first and most elemental sense -- something that happened. Because we've reported thoroughly on this issue since the beginning, we felt our readers probably already had a sense of the scope of what was, indeed, a tragedy, without our elaborating the point. Additionally, space restrictions in AVflash require us to be rather spare with our words sometimes.

Lift Doesn't Suck I would like to make it clear that I do not know Roger Long, have never met him, and I don't know anything about him. However, I was disturbed when I read his article. He may have gotten interested in this kind of theory independently, but my friend Gale Craig has been working on Newtonian lift theory for many many years. He finally published a book in 1995 called "Newtonian Aerodynamics Fundamentals" ISBN 0-9646806-0-2. Since that time, work suspiciously similar to his has appeared in several places. One author even published an article with material lifted directly from Gale's book! I am not saying that this has happened in this case, but I do think it bears investigation. You can get in touch with Gale at gcraig@iquest.net. I hate to be the bearer of this kind of comment, and I realize that you had no way of knowing about this in advance. But, I do like to see credit where credit is due. AVweb responds... Let me be very clear, there is NOTHING, original in my article and I do not claim to have discovered anything. I felt pretty clever for coming up with the wave analogy of circulation as I have not seen it any of the sources I have read. It is such an exact description of the nature of the motion however, that I would be stunned to learn that no one has used it before. I had not heard of Mr. Craig's book prior to Mr. Rice's post in the comments section. It sounds like one I would enjoy reading. If it is an accurate explanation of the processes of aerodynamic lift, it must contain many conceptual similarities to my article for we are describing things that take place in the same physical universe. The idea that there is something called "Newtonian Lift," which could be the subject of squabbles over its discovery, I find a bit absurd. Many readers seem to have missed the between-the-lines point of my article. Things which appear to be the subject of "either / or" controversy are often, in fact, different aspects of the same underlying principle. I'm going to belabor this a bit in the next segment. Lift is a process that takes place according to the physical characteristics of the universe. Descriptions which enable us to predict and understand how these characteristics will determine the nature of discrete events were developed by Newton, Bernoulli, Kutta, and many others. These are all partial descriptions of the same underlying reality. I claim only to have taken the discussions and descriptions of others and summarized and presented them in a way that made them accessible and entertaining to AVweb readers. Many wrote saying that the article enabled them to understand lift for the first time. They did not need AVweb or my article to do that. They could have combed the internet, read books, pondered, and figured it out for themselves. Instead, they got it from a brief article here. That is the only service we intended to provide and I am pleased that it appears to have succeeded for so many. --Roger Long, Author of Lift Doesn't Suck |

Flying Real-World Weather I enjoyed your Mike Busch's article in AVweb titled Flying Real-World Weather. I began wx-flying in 1972(?) when I got my multi in a Beech D-18 and the owner promptly sent me off on a trip to N.Y. or Chicago (escapes me now). I didn't like the weather forecast -- tried to back out of the trip and he said, "Fine, Joe'll take it" -- I went. My boss continually admonished me that "it's never as bad as they say." He wasn't always right, but for the most part I've found that to be the case, just as Busch said. I don't fly the night cargo runs any longer, I fly my well-equipped 1968 Cessna 180 some 250-300 hours per year. Like Busch, I don't have to cancel many trips because of weather -- I say "many" because I do cancel occasionally when there are just too many storms, too much ice (or freezing levels too close to terra firma), etc. And, I don't fly through much bad weather because it just ain't there most of the time! Anyway, I really enjoyed the article and forwarded it on to several of my students.
AVweb responds... Thanks, Don! --Mike Busch, Editor-in-Chief |

Take The Aviation Trust Fund Off-Budget? AOPA and others have been calling on Congress to take the aviation trust fund "off-budget" so its monies can be used for aviation instead of making the government books look good. This sound great, but there is a bad side-effect. If the fund is taken off-budget the FAA can also spend it as it wishes without accountability to anyone. Won't happen? Don't be too sure! The FAA has a long history of spending money in strange and unwanted ways. Can you imagine the attraction billions of loose dollars would hold to an agency thirsting for funds? Thus we have an interesting dilemma: keep the fund as it is, protected by budget procedures,and watch it do nothing, or take it off budget and wonder where it went. The problem is that the FAA isn't doing its job to get the trust fund dollars to worthwhile projects. If Congress can move the fund off-budget it can also force the FAA to do the job it's supposed to do. If the process is too complex, it can be simplified. Before we give away the fund we should make sure its manager is worthy. AVweb responds... Interesting perspective, Richard. Definitely food for thought. --Mike Busch, Editor-in-Chief |

Airport Expansion As the continuous flow of BS comes out of every "liberal" politician, America sinks deeper and deeper into the quick-sand of socialism with its accompanying long lines and congestion caused only by the lack of proper government services. Our airports, roads, and bridges crumbling. They are not crumbling because Americans do not pay enough of their hard earned dollars in taxes to fix them. They are crumbling because the politicians would rather use those tax dollars for buying the votes of the people who "want what someone else has." Proper government services are being displaced by social programs that simply transfer money from one group and hand it over to another group in trade for their vote at the next election. The average American family today pays $15,400 in Federal taxes, and fully half of that is "transferred" to other families instead of being used to provide adequate proper government services for all American families. Americans have become a large flock of sheep that are being herded down the wrong path by politicians who "need" their jobs, instead of politicians who are asked to serve by their piers. They get $145,000 a year, $800,000 to run their offices, and a 2.3 million lifetime retirement after serving two terms. They promise more and more to whatever special interest group will listen and vote for them. And they deliver more and more with more and more transfer payments. If your neighbor cannot come into your home at night and steal money off of your dresser because he thinks he needs it more than you, then why can a politician come into your home through your tax return and take the money and give it to your neighbor because he thinks the neighbor needs it more than you do? If campaign finance reform gets by the Supreme Court, it will be over for America as we knew it. Airports that do not expand should be restricted to a set number of travelers and aircraft that can be safely served! If the public hates airports in their back yard, then let them ride the busses or trains or drive on the bumpy superhighways. Having operated both Lear and Citation jets in and out of every busy major U.S. airport, I can honestly say that I have never seen a crowded airport situation that would not be alleviated by MORE RUNWAYS, MORE TERMINALS AND MORE PARKING, and the proper maintenance of all of the above. AVweb responds... Be careful what you wish for, Ed. If airports that do not expand are restricted to a set number of travelers and aircraft, who do you suppose will be restricted more severely: GA or air carriers? --Mike Busch, Editor-in-Chief |

Richards-Gebaur Memorial Airport I'm not a pilot, but have loved aviation all my life, and was in the USAF during the Korean War. I'm deeply involved with the "Save Richards-Gebaur Memorial Airport" movement. As you may know, the city of Kansas City. Missouri has entered into a sweetheart deal with Kansas City Southern railroad to close RG and convert it into a rail/ truck/ freight hub so as to cash in on NAFTA! They want to lay rails on our 8700 foot runway, which will destroy the airport!! There have been a number of secretive, closed-door deals made between these two entities, and closing dates have been announced several times. So far, we've held them off. We even made them bring it to a public vote, but they set it up so the people least affected could vote on the rail hub. We lost by a mere 3000 votes. Thanks to the good offices of the AOPA, the FAA has taken another look at it. We may be like Chumps playing Stud Poker, but we're still fighting them. At this point KC declares they will close RG on 12/31/99. We're not against the rail hub concept, we just don't want it at RG. Kansas City Southern railroad owns five other rail yards in KC, and they've stated they don't need RG. But KC wants to dump RG because they don't want it to compete with two other airports; one which is 60 miles away from RG and the other, nearly 20 miles away. We would gratefully accept any assistance anyone would wish to bestow upon us. We want to keep RG open for the sake of General Aviation in South Kansas City. The business is there, and we can get it if we can keep RG open. |

Cessna 152 Safe For IFR? I have two safety-related questions: 1. I am considering searching for and purchasing a used 152 (172 is too expensive at the moment) and certifying it for IFR flight. This could be accomplished on most 152's simply by doing the required checks and calibrations, since they already have gyros and one VOR. I called a local avionics shop (Priester Aviation at PWK) who said it would cost $5000-7000 to put in a 2'nd nav/com/gs, marker beacon and DME...perhaps used. I have noticed that most 152s are flown VFR only. Is this because they are not safe IFR aircraft, or because they are too slow and don't carry enough weight for most pilots needs? My mission is primarily local, solo VFR flights with 200-500 mile IFR trips in reasonable weather every few months. 2. There are many articles in AVweb on the value of FlightSafety and other recurrent training. For single pilot IFR in a low-performance, simple aircraft such as a 152 or 172 with no autopilot, is FlightSafety type training appropriate, or am I safe with an every-three-months instrument proficiency check from a CFII? AVweb responds... There is no reason a 152 would not be a safe aircraft to fly IFR, provided you are careful to stay out of icing conditions and weather capable of producing strong up- and downdrafts. If you're thinking of spending $5000 to $7000 to add a second nav/com/gs and DME, it might be worth considering installing an approach-certified GPS/COM instead. The cost of FlightSafety training is probably prohibitive and somewhat overkill for a simple aircraft like the C152. However, annual sim training using a simple simulator like an AST-300 or even a PCATD would be an excellent supplement to your semiannual Instrument Proficiency Checks. A skilled sim instructor can pack as much training value into one hour of sim time as you'd get in three or four hours of in-airplane training. --Mike Busch, Editor-in-Chief |

Unionization of FAA Headquarters Last week you published an "On The Fly" notice that "NATCA submitted petitions to become the exclusive bargaining unit for an additional 1,400 non-management FAA employees... " What you failed to include in this notice was that AFSCME (American Federation of State County and Municipal Employees) also submitted petitions to become the exclusive bargaining unit. What makes this real interesting is that AFSCME had over 400 votes from the Air Traffic (ATS) community while NATCA had only 20. Hmmm... This leads to a lot of questions. Isn't it just a little strange that a non aviation union can gain a solid foothold in the FAA so easily? Why didn't NATCA get the 400 votes? Is there something wrong with NATCA's approach?????? Why don't you run an article on why FAA employees feel the need to organize now? An insider's take is that FAA employees are feeling very threatened by the new Core Compensation program. This may result in many employees bailing out of the FAA because they can see serious storm clouds ahead... AVweb responds... Robin, seems to me that the reason FAA employees feel the need to organize now is obvious: The agency has put a moratorium on pay increases affecting all non-union employees. As we reported some time ago in AVweb news, this has even caused the FAA lawyers to start making noises about becoming unionized. --Mike Busch, Editor-in-Chief |

USAF Termination of T-3A Program The T-3A has been grounded by the USAF since '97. The news is that the AF decided that it will never come back. They made the current stopgap civilian training program permanent and expanded it to 50 hours with a private pilot's license. That's horrible news. It essentially means that cadets at the USAF Academy and in many ROTC units will learn about flying from CFIs rather than military pilots. The CFIs know flying, of course, but have no way to answer cadet questions on what they may be getting into and CFIs can't be military roll models. Between a quarter and a third of the pilot qualified cadets initially turn down pilot training -- partially because they have bad rumors on what a pilot's life is like.

Cellphone Use In Aircraft May Not Be Dangerous I can't speak to the RTCA study results, and I certainly can't dispute the claims of Mr. Sheehan. I can pass along my own experiences, however, so I will. I fly right seat in a Citation in corporate service. Both the Captain and I have found that when cellphones are activated (i.e., ring, place a call, etc.) both in flight and on the ground, they set up a powerful interference with the headset. The amount of interference is dependent on the distance of the phone to the radios, but in a smaller jet, the noise created in the headset is definitely between noticeable and ungodly loud. Pagers do this to a lesser extent. You can hear the same effect by sitting in front of your computer speakers and activating your cellphone Case in point: we were on approach to VNY, talking to SOCAL Approach, looking for traffic when someone's cellphone rang. Both of us heard this shrieking/buzzing sound in our headsets (worse than your worst case of frequency heterodyning), prompting us to remove them until it stopped. If that doesn't count as a distraction, I'm not sure what does. You may be sure that we instruct passengers to deactivate their cellphones and pagers prior to taxi now. |

ATC Delays The FAA's solution to ATC delays is akin to the fox guarding the hen house. As one who plies the nation's airways every day of my working life, (I am a Boeing 737 First Officer for a major US airline) I can tell you that the FAA is the problem, not the solution. As I see it, there are three problems: 1. FAA Air Traffic Control management is playing political games; deliberate slow downs and inefficient flow of air traffic to justify increased funding and additional personnel. This is not just my idea. I have confirmed this with line ATC controllers. With absolutely clear weather I have been given 30-40 minute holding patterns when arriving at major hub airports. 2. This Administration is also playing political games. By causing delays they are attempting to justify additional "user fees" to bolster the budget requests. They want to charge the airlines a fee for each radio transmission. They want to charge general aviation pilots a fee for weather briefings, flight plans, and ATC services. But user fees are already being paid. A percentage of each airline ticket, and a percentage of each gallon of gasoline purchased by general aviation users, goes into the Aviation Trust Fund. There are billions of dollars in that fund right now. But they can't be spent to modernize the ATC system because when they are spent they are accounted for on the federal budget. This is just another attempt by the Administration to covertly raise taxes. 3. FAA management attempts to fly the airplanes for the pilots. Re. the article's paragraph, "Give the FAA's air traffic command center in Herndon, Va, greater authority over rerouting planes during weather problems and other events that slow air traffic." ATC admits that their weather radar is not as good as on-board radar on the aircraft. But when weather moves over a route, ATC attempts reroutes, rather than allowing pilots the latitude of their own diversions around or through weather. This unnecessarily increases congestion and delays throughout the system. I offer two solutions: 1. The GAO or NASA, not the FAA or Dept. of Transportation, should study the nation's air traffic system and make recommendations. It really is broken, and is in need of fixing, but the FAA cannot be trusted to be other than self serving. 2. I encourage all citizens, especially those who travel by air frequently and experience delays, to write their Congressman. Encourage Congress to support pending legislation to remove the Aviation Trust Fund from the federal budget. Free up these dollars from the political maneuvering of the Administration. Believe me, the airlines are doing their best to safely get their customers to their destinations on time. The problem is with the FAA. |

USAF Termination of T-3A Program As a former T3A instructor pilot, I think there is quite a story (read SCANDAL) on the grounding of this program. All internal USAF documents conclude there is nothing fundamentally wrong with the airplane. The Test Flight Center at Edwards did extensive testing on unmodified aircraft. That report praised the aircraft as is. One of many Broad Area Reviews is available on the USAFA web site, and gives a lengthy history of Flight Screening, the three accidents (and how the primary cause was instructor pilot inexperience, not the aircraft), and recommendations to solve existing problems. The more dramatic of which was to turn the Academy flying over to civilian IP's. The engine stoppages included a majority on the ground after trying to start a cold engine, with only a handful of in-flight stoppages, most of which occur during a spin entry with low airspeed and yaw on a lightweight propeller. Most of this information is public record. The IP corps at Hondo had utmost confidence in the aircraft and its mission and continue to be numbed by this latest turn of events. My speculation is to focus on GEN Mike Ryan (COSAF). He refuses to talk openly about his reasons. With men like this in power, it's no wonder we can't fight a war below 15,000 feet. It's easy to understand that this was not his program, but to set back pilot training below achievable levels is not in the best interest of the USAF or the country. It might however, be in the best interest of Mike Ryan. Sending SUPT-bound pilot-trainees to local flight schools has been done ad nauseum in the past, yet the current people in charge of the USAF fail to look at their own history--quite a stragic blunder if this is indicative of their myopia. Their praise of this current flight training program is sickening at best. When I instructed, we received all types of background trainees, from zero-timers (which the program was designed to handle) to commercial and instructor types. For me , I would prefer a zero-timer to a low time Private Pilot. Being able to fly straight and level meant very little, and that Private Pilot was as likely to get airsick as anyone else. I feel for the T37 IP's, who for the last two years have not had students with any clue of military flying. No wonder the attrition rate has soared, as it has on downstream, including advanced training in F15 Eagles. At maximum capacity with no attrition, the USAF cannot meet its requirements. Why in the world would someone want to sabotage the future of the USAF? Maybe to save their retirement, or to promote UAV's? The answers do not come easily, but I would like some real answers.

Cellphone Use In Aircraft May Not Be Dangerous This is more of an FCC issue than an FAA issue. However, as a Captain of a regional airliner, I would MUCH rather have all cell phone use prohibited if I'm shooting an approach down to minimums, Thank you very much!!!

What Happened to Regional Aircraft? As a First Officer for a "major" regional airline it is very disappointing to see the recent shift in our industry. This shift is one which has nearly eliminated the Regional Aircraft from the scene of many mid-sized Commercial Airports. This is very apparent here in the northeast where airports like Tweed New Haven, Bridgeport, Worcester, and to some degree Binghampton Airports have seen air service dramatically reduced. To me, it seems the larger airports are getting an excess of service while the airports that need and can support it miss the boat. For the record, New Haven saw 250,000 passengers through its airline terminal when the airport was at its peak in the early 90's.Many airports have proven they can support moderate levels of air service. This to me does not indicate lack of ridership. Regional aircraft like the ATR and Dash 8 were built to bring major airliner amenities to midsized communities, unfortunately they have not been doing this lately. Would Like to hear your thoughts. |

Cellphone Use In Aircraft May Not Be Dangerous In his original article in the Wall Street Journal, Jon Auerbach's explanation of why one shouldn't use a cell phone in flight wasn't all that clear. Not surprisingly, NBC news picked up on it and misreported the whole story. Here's the rest of the story: The concept of cellular telephony assumes that the range your cellular telephone can transmit is very limited. If you're standing on the ground, you will not be able to send a signal much past the nearest six or seven cells. These cells aren't all that large, ranging in size from maybe a square mile to maybe 50 square miles in sparse rural areas... Once you have a cell or two between you and another site, the radio channels can be reused. All this falls apart the moment you are more than a few hundred feet in the air. As anyone who has tuned in Unicom knows, even at 1000 AGL, you'll hear other aircraft several hundred miles away. So what happens? A cellular telephone used in flight would saturate the one channel it is on for several hundred miles in every direction. THAT is why you shouldn't use one in flight. The problem is on the ground with the cellular telephone companies -- not in the air. That is why the FCC wrote the regulation regarding the use of a cellphone in flight. It has nothing to do with protecting the aircraft and everything to do with protecting the cellular telephone companies on the ground. So if anyone chooses to use a cellular telephone in flight, just remember this: You'd better have a bona fide emergency or you'll face a cellular telephone bill you'll never forget! AVweb responds... Don't be so sure about that phone bill, Jake. The WSJ article stated that although the FCC prohibition against in-flight cellphone use is routinely violated on a daily basis, no one has ever been prosecuted in the U.S. for such a violation (although there have been prosecutions for in-flight cell use in the U.K. and Europe). --Mike Busch, Editor-in-Chief |

EVAC-U8 Smoke Hood I just ordered two of the EVAC-U8 smoke hoods recommended by Mike Busch in his review article. I thought you might be interested in knowing why. Having just survived the UK's worst train crash in 40 years and having to escape from a coach filling with acrid smoke from surrounding burning coaches, this seems like a small price to pay. At least 40 people died.
AVweb responds... Thanks for sharing that, David. Glad to hear you're okay! --Mike Busch, Editor-in-Chief |
