Put your aviation knowledge to the test with these interactive quizzes.

Quiz #75 -- Aerodrome Operations

You can successfully fly hundreds of miles across burning sands, frozen tamarack, and deadly L.A. freeways, but all that Zen-like aero-bliss can turn to grief if you don't understand the operating rules in the airport environment. Have fun navigating the following scenarios.

Quiz #74 -- Hold, Circle, and Yield Right-of-Way

Flight opens the entire world to your imagination, so imagine yourself in the IFR-meets-VFR real world where you have to know what the other pilots are up to.

Quiz #73 -- IFR Charts And Procedures For All Pilots

Rumor has it that some pilots fly inside clouds. Yikes! How can they see the interstate highways? VFR pilots should have at least a passing acquaintance with IFR procedures if only to know where IFR traffic might appear. All instrument-rated flyers could use the occasional brush-up on instrument terms and procedures.

Quiz #72 -- Grab Those VFR Sectional Charts And Fly

FAR 91.103 says that you need "all available information" before launching on any flight. Yeah, right. Where's a PIC supposed to glean all that stuff? Surprisingly, much of what you need -- IFR or VFR -- is on the lowly VFR sectional chart. But you need to decode a few things ...

Quiz #71 -- Special Use Airspace

Temporary Flight Restrictions (TFRs) have become permanent, roving annoyances to pilots. Other Special Use Airspace (SUA) restrictions have vexed aviators for decades. Test your knowledge of off-limits airspace.

Quiz #70 -- Mommy, Where Do Controllers Come From?

The art and science of air traffic control (ATC) began life in humble surroundings without exerting much control. Let's peak behind the FAA's historical curtain to see who pulled the early levers of aviation power.

Quiz #69 -- Talk The Talk

Whether you're talking on a busy air traffic control (ATC) frequency or some sleepy uncontrolled airport's CTAF (Common Traffic Advisory Frequency), how you sound determines how others will treat you. When the phraseology is flying fast do you sing like a 747 captain or squawk like Donald Duck? See how you'd treat these snatches of aviation verbiage.

Quiz #68 -- Additional Ratings and Endorsements

Some pilot privileges require a written exam and a grueling checkride administered by a grumpy examiner. Others are gained through additional training from a friendly CFI and a low-anxiety sign-off. Know the difference?

Quiz #67 -- Is Your Aircraft Airworthy Of You?

Whether you own or rent, before going aloft it's important for the pilot in command to calculate just how many pounds of paperwork it takes to make the aircraft airworthy. From annual inspection dates to transponder certification rules there's a boatload of regs to apply. See how many you can recall.

Quiz #66 -- Just How Current Are You?

While sorting your laundry, a pilot certificate slips from your Dockers' pocket. "Nice pants," you think and then notice your name on the certificate. You decide to go flying, but before rolling the Turbo-Ercoupe out of the hangar, you should preflight your pilot paperwork.

Quiz #65 -- A Touch of Class Airspace Review

Your flying is truly a class act, so you should have no trouble dissecting and labeling the various classes of airspace. What can get sticky are all the nit-picking regulations that apply inside this alphabet jungle. Note: When international differences apply, the answers in this test presume the flight is within U.S. airspace.

Quiz #64 --So You Want to Get an Instrument Rating

Whenever there's a low overcast or reduced visibility at the local airport and CAVU a few miles away, the non-instrument-rated pilots often sit around the pilots' lounge and talk about this and that while waiting for the weather to improve. But in the back of each pilot's mind there's a thought that begins with, "If I had an instrument rating ..." What is it that keeps pilots from getting instrument rated? Is it the lack of time, money, confidence, knowledge about the privileges and responsibilities of the instrument rating or the training required? This quiz encompasses those privileges, responsibilities and training requirements for obtaining and utilizing an instrument rating in the United States. All questions assume that the pilot has an airplane single engine land rating on a private or commercial pilot certificate issued by the FAA.

Quiz #63 --Aviation Weather Products

Most pilots are familiar with the Aviation Routine Weather Report (METAR) and the Aviation Terminal Forecast (TAF) products of the National Weather Service (NWS). There are many other aviation weather products available to pilots, who must obtain "all available information" for any flight (according to FAR 91.103). The purpose of this quiz is to refresh pilots' knowledge regarding those weather products, including the official designators (METAR, TAF, etc.), location of the originating sources, and the content of the products. Most of the information for this quiz can be found in FAA publication AC 00-45E, Aviation Weather Services.

Quiz #62 --Special IFR

Pilots who fly under Instrument Flight Rules in the United States are expected to know and to follow the IFR regulations and procedures as written in the Federal Aviation Regulations (FAR) and the Aeronautical Information Manual (AIM). Some of the procedures are used only on relatively rare occasion in certain areas of the country or only at a small number of airports, so it's quite possible for a pilot to fly for years and accumulate thousands of flying hours under IFR and never have to deal with these procedures, while pilots in other places use them on a weekly basis. This quiz is designed to test your knowledge of some of these lesser-known (and hence "special") IFR procedures.

Quiz #61 --Very High Frequency Omni Range

VOR navigation has been around for a long time, and it's not likely to go away for quite some time. Although LORAN and GPS navigation have both threatened to make VOR navigation obsolete, that's very unlikely to happen in the near future. Knowledge of how the VOR system works (including both ground and airborne equipment) is essential for both VFR and IFR pilots. This quiz will refresh and test your knowledge regarding this important navigational tool.

Quiz #60 -- National Transportation Safety Board, Part 830

Most pilots will never be involved in an aircraft accident. Nevertheless, it's important for pilots to know their legal responsibilities if they are involved in an aircraft accident or certain incidents in the United States, or anywhere if a U.S.-registered aircraft is involved. NTSB Part 830 specifies what those responsibilities are, and AVweb's Irv Siegel has a quiz is designed to test your knowledge and refresh your memory regarding this information.

Quiz #59 -- The Price Is Right!

Pilots are inundated with numbers -- airspeeds, fuel flows, radio frequencies, takeoff and landing distances -- but to most of us, the numbers that matter most are the ones preceded by dollar signs. Do you know what it costs to rent an airplane, to buy a gallon of 100LL, to renew a medical certificate, or to lease a tee-hangar? Have some price-guessing fun with Irv Siegel's latest interactive quiz.

Quiz #58 -- More Pilot/Controller Glossary

Our Quiz #50, "Pilot/Controller Glossary," was one of our most popular, and many readers asked for more. Well, here you are! Once again, this quiz is based on the Pilot/Controller Glossary (in the FAA's AIM), whose purpose is to define and explain the terminology used by pilots and controllers when communicating on ATC frequencies. You're invited to test and to extend your knowledge of that terminology.

Quiz #57 -- Flight Instructor Practical Test

The FAA has just published a new Practical Test Standard (PTS) for the Flight Instructor Airplane certificate. The CFI-A checkride has a justly deserved reputation as one of the toughest in aviation. Whether you're already a CFI, a pilot who aspires to become a CFI, or just curious about what a flight instructor practical test is all about, Irv Siegel's latest interactive quiz will give you a preview.

Quiz #56 -- Pilot Proficiency Awards Program

The Federal Aviation Administration has established a Pilot Proficiency Award Program to recognize pilots who participate in recurrent proficiency training. Advisory Circular AC 61-91H details the requirements for this program, and its benefits for participating pilots. Brush up your knowledge of this important subject by taking Irv Siegel's latest interactive quiz.

Quiz #55 -- Cleared For The Approach

The ATC instruction "cleared for the approach" allows a pilot flying under IFR to descend and land according to procedures that must be adhered to if the pilot is to conclude the flight safely. Although most of these procedures are straightforward, there are a number of "gotchas" that can trap the unwary pilot. Check your understanding of these procedures by taking Irv Siegel's latest interactive quiz.

Quiz #54 -- Acronyms, Abbreviations and Contractions

Pilots are often confused by the numerous acronyms, abbreviations, and contractions that are found in weather reports and forecasts, regulations, NOTAMs, advisory circulars, etc. You’re probably familiar with the most common of these shorthand notations, but there are others that are less frequently seen but still important to anyone concerned with the safety of flight. Irv Siegel’s latest interactive quiz will test your knowledge of these acronyms, abbreviations and contractions -- some common and others less common but important.

Quiz #53 -- Density Altitude

Every pilot knows that aircraft takeoff and landing performance varies with field elevation, temperature, humidity, altimeter setting, runway slope, wind velocity, wind shear, turbulence, etc. Some of these factors are consolidated into the quantifiable term "density altitude," which then can be used to help predict aircraft performance (or lack thereof). A solid knowledge of density altitude -- what it is, how it's determined, and the effects that it has on aircraft performance -- is essential for all pilots. Solidify yours by taking Irv Siegel's latest interactive quiz.

Quiz #52 -- Rules of Thumb

Rules of thumb help to cut pilot workload by substituting a simple rule for what could be a complex calculation. Irv Siegel’s latest quiz is based on a number of such very useful rules. You should be able to answer these questions without resorting to your whiz-wheel, electronic calculator, computers, or even pencil and paper ... and if you can't now, the quiz answers will teach you how.

Quiz #51 -- Up, Up, and Away!

Balloon flying predates powered airplane flying by over two centuries. Some consider it sport flying at its purest. Knowledge of wind and weather, regulations, and proper flying technique are every bit as important for balloon pilots as it is for pilots of other types of aircraft. Brush up your ballooning knowledge by taking Irv Siegel's latest interactive quiz.

Quiz #50 -- Pilot/Controller Glossary

For clear and unambiguous communications between pilots and controllers, it's vital that there be agreement about the meaning of words. In the Aeronautical Information Manual, the FAA has published a Pilot/Controller Glossary that defines and explains the terminology used by pilots and controllers when communicating on ATC frequencies. See if your knowledge of this lingo is up to snuff by taking Irv Siegel's latest interactive quiz.

Quiz #49 -- Basic Aerodynamics

Knowledge of basic aerodynamics is necessary for anybody wishing to obtain a pilot certificate. As the years go by, many pilots fail to refresh their knowledge of this subject, or to increase it beyond the simple explanations of lift, weight, thrust, and drag. Assess your aerodynamic knowledge by trying your hand at Irv Siegel's latest online quiz.

Quiz #48 -- Basic Attitude Instrument Flight

Two different approaches to attitude instrument flying are "control and performance" and "primary and supporting." Many CFIIs favor one of these methods over the other, with the result that many pilots learn only one method. Knowledge of both methods gives a pilot more confidence while flying on the gauges, as each method reinforces the other. Irv Siegel's latest online quiz deals with the basics of both methods.

Quiz #47 -- Security Control of Air Traffic

We all hope that the terrifying and tragic events of September 11, 2001, will never be repeated, and that any future attempted terrorist attacks will be prevented from being carried out. To this end, pilots must be well versed in ATC security procedures that apply when penetrating an ADIZ, when intercepted, and in the event of a national emergency. This is the subject of Irv Siegel's latest online quiz.

Quiz #46 -- Aviation Facts and Myths

In the musical "The King And I," the King says, "In my head are many facts of which I wish I was more certain I was sure. Is a puzzlement." Similarly, in aviation there are many "facts" that we think we know, but that turn out to be myths. See how you do separating myth from fact in Irv Siegel's latest online quiz.

Quiz #45 -- The FAA's New Instrument Flying Handbook

The FAA recently published a brand new version of its "Instrument Flying Handbook" with a brand new identifying number: FAA-H-8083-15. This new edition differs substantially from its predecessor (AC61-27C), and features up-to-date illustrations and information about all aspects of instrument flight, including GPS and other recent avionics advances. It's a "must read" for every instrument pilot and instrument student. Irv Siegel's latest interactive quiz offers a taste of what it has to offer.

Quiz #44 -- Becoming A Commercial Pilot

Obtaining a private pilot certificate is a challenging and rewarding experience. Many pilots then go on to obtain an instrument rating, thereby making their pilot certificates much more useful. But, is there reason to go after the commercial pilot certificate if one does not have a career in aviation in mind? For many pilots, the answer is a resounding "Yes!" Certainly, the training involved in obtaining that certificate will make any pilot sharper and more proficient, and Irv Siegel's latest interactive quiz is a good place to start.

Quiz #43 -- Name That Aircraft!

How well do you know the different types of airplanes that you see in the sky? Given a detailed description off an aircraft -- wingspan, cruising speed, number of engines, aerodynamic configuration, etc. -- can you figure out the aircraft type? If so, then you should do well on Irv Siegel's latest interactive quiz, which tests your ability to match the descriptions and parameters of different aircraft with their names.

Quiz #42 -- Aviation History

Most AVweb Brainteasers have focused on pilot knowledge that's important for safe, efficient, and legal operation of aircraft. This one is a bit different. Knowledge of aviation history isn't necessary for a pilot to safely, efficiently, and legally fly in today's airspace, but a knowledge of the contributions of aviators in years gone by is necessary for us to truly appreciate our ability to take to the skies in the 21st century. Our debt to our predecessors can only be paid if we continue their quest for knowledge and flying experience.

Quiz #41 -- Medical Facts for Pilots

The Civil Aeromedical Institute (CAMI) is the FAA organization responsible for medical certification, research and education. The CAMI Web site features a series of "Medical Facts For Pilots" brochures covering subjects like alcohol, altitude sickness, OTC medications, pilot vision, seat belts, smoke toxicity, and human factors. These are the basis for Irv Siegel's latest interactive quiz. Try it ... you'll learn something!

Quiz #40 -- Safety Guide for Private Aircraft Owners

The FAA offers many useful publications for the aviation community, but some of them are little known and seldom read. One of these -- FAA publication FAA-P-8740-4A, "Safety Guide for Private Aircraft Owners" -- is the basis of this month's interactive quiz by Irv Siegel. Test your knowledge on a wide range of subjects important to GA pilots: fuel and oil, spark plug fouling, tire pressures, carbon monoxide, propeller nicks, maintenance test flights, and more.<;br>

Quiz #39 -- Aviation Safety Reporting Program

Best known to pilots for its get-out-of-jail-free provisions, the FAA Aviation Safety Reporting Program (ASRP) is designed to encourage the free and unrestricted reporting of safety-related information by users of the National Airspace System (NAS). The ASRP utilizes the National Aeronautics and Space Administration (NASA) as a third party to receive aviation safety reports from users and de-identify those reports to protect submitters from FAA prosecution. For pilots to use the ASRP effectively, it's necessary for them to understand exactly how the program works. This quiz will test your knowledge of the ASRP, and will enable you to fill in any gaps in your knowledge regarding the program.

Quiz #38 -- VFR Cross-Country

Most airplanes are designed for traveling from airport to airport, transporting people (and sometimes baggage and packages) from point A to point B. In such cross-country flying, a pilot's goal should be to make each flight safe and efficient and pleasurable, so that every passenger is eager to fly again on a future trip. Irv Siegel's latest interactive quiz is designed to make pilots think about some of the many aspects of a VFR cross-country flight in the United States and how they would handle each of the situations described.

Quiz #37 -- ILS Components

When the ceiling is low and the visibility is poor and the wind is howling, pilots need all the help they can get in order to navigate to the runway and make a successful landing. The most common precision instrument approach is the Instrument Landing System, and instrument students spend many hours practicing and honing their skills at flying a stable and accurate ILS approach. Keeping the needles centered is a pilot's first priority, but it's also important to have a good working knowledge of the entire ILS system, and how each of its components contributes to the pilot's positional awareness. Irv Siegel's latest quiz will test your knowledge of those components and the tolerances involved in the design and execution of an ILS approach.

Quiz #36 -- VFR Weather Minimums

Okay gang, it's back to basics with Irv Siegel's latest interactive quiz. In the United States (as well as just about every ICAO country), weather minimums for VFR flight vary according to the type of airspace, height above the ground, height above mean sea level, and whether it's daytime or night. Most of us learned these weather minimums when we were student pilots, but in the intervening years our knowledge may have gotten rusty, and in some cases the regulations may have changed. Take this quiz and refresh your knowledge of the weather minimums required to fly under visual flight rules.

Quiz #35 -- Terminal Instrument Procedures (TERPS)

Instrument departure and arrival procedures in the U.S. are designed in accordance with FAA Order 8260.3B, titled "United States Standard for Terminal Procedures" and affectionately nicknamed "TERPS." Pilots who are familiar with the criteria used to design instrument procedures are less likely to make critical mistakes when executing them. Irv Siegel's latest interactive quiz puts your TERPS knowledge to the test.

Quiz #34 -- Cessna 150

Many pilots have learned to fly in the venerable Cessna 150 and its successor, the 152. The 150 remains a favorite for flight schools all over the world, and is the focus of Irv Siegel's latest interactive quiz. For those pilots who have owned, operated, or learned to fly in one of these aircraft, this should be a relatively easy exercise. For others, it's an opportunity to learn about one of the most popular training aircraft in the world.

Quiz #33 -- Knowledge Test Questions

Four times a year, the FAA makes changes to its question banks for virtually every knowledge test. Irv Siegel's Brainteaser for this month consists of new and changed questions recently added to the Commercial Pilot, Instrument Pilot, and Airline Transport Pilot test question bank. Irv has chosen the 15 new questions that he considers most relevant to actual flight in the real world ... AND he's furnished the answers to these questions, which the FAA does NOT do.

Quiz #32 -- Frequency Change Approved

In the early days of aviation, pilots didn't have to contend with radio communication and navigation. Nowadays, though, knowledge of what frequencies to expect will lead to a more enjoyable aviating experience. (Who among us has not tried to put a VOR frequency in a communications transceiver, or vice versa?) Try this frequency quiz by Irv Siegel, and test your knowledge regarding frequency assignments.

Quiz #31 -- Visiting Las Vegas

Las Vegas, Nev., is a favorite destination for general aviation and air carriers alike. Hemmed in by high terrain and gigantic military restricted complexes, the airspace can get very busy and the controllers very unforgiving of pilot goofs. There's a lot of critical information packed into the Terminal Area Chart and the Airport Facility Directory, and Irv Siegel's latest interactive quiz will test your ability to dig out that information. (Hint: It's harder than you think.)

Quiz #30 -- Specialty Takeoffs and Landings

How long has it been since you had to do a soft field takeoff, or a slip to a landing over an obstacle? Other than for practical exams and perhaps for the occasional flight review, most pilots rarely perform anything but normal departures and arrivals. Irv Siegel's latest interactive quiz is designed to refresh your knowledge and get you ready to go out and practice some of these specialty takeoffs and landings.

Quiz #29 -- Pressurization

As pilots move up to bigger and faster aircraft, there is a natural desire to fly at higher and higher altitudes. At first, breathing supplemental oxygen is satisfactory, but many pilots find that costly and inconvenient (as do their passengers), not to mention that breathing even pure oxygen isn't enough at very high altitudes. It is then that pilots turn to pressurized aircraft. Pressurization enables us to fly at high enough altitudes to maximize fuel efficiency, get above most inclement weather, and take advantage of strong tailwinds, all without having to be tethered to an oxygen mask. Irv Siegel’s latest interactive quiz deals with aspects of pressurization that are important to any pilot who is thinking of stepping up to a pressurized aircraft.

Quiz #28 -- Slow Flight and Stalls

It takes knowledge, talent, and practice to be able to fly an aircraft at the edge of its performance envelope, especially at the lower airspeed limits. Pilots learn some of these maneuvers in preparation for a private, commercial, or flight instructor practical test, but unless they are practiced on a regular basis, knowledge decays and skill atrophies, often to the point where the benefits of the original training are all but lost. Irv Siegel's latest interactive quiz will help you gauge how much you remember about this stuff, and perhaps serve as a reminder that we all need to get out and practice it from time to time in order to maintain our basic pilot skills.

Quiz #27 -- Becoming a Flight Instructor

Did you ever have the urge to teach others to fly? Did you hold back from doing it because you thought that it was too difficult or costly to become a certificated flight instructor? While it's true that there's a whole new set of skills required for teaching others to fly, the main requirement is that you be able to communicate effectively with other people. Irv Siegel's latest online quiz may help you decide whether CFI-dom is for you.

Quiz #26 -- METAR, Revisited

The FAA recently released a new update of its "Aviation Weather Services" advisory circular (AC 00-45E). It's not yet in print, but can be downloaded from the FAA's Flight Standards Web site at http://www.faa.gov/avr/afs/afs400/. Since this newly-revised AC discusses how to interpret and use coded weather reports, it seemed to AVweb's quizmaster Irv Siegel like a good time to revisit the topic of decoding METARs, which many pilots find to be the most cryptic of those reports. Have a shot at Irv's latest interactive quiz and see whether you need a brush-up on your cryptographic skills.

Quiz #25 -- Becoming An Aircraft Owner

Every renter-pilot harbors a secret (or perhaps not-so-secret) desire to become an aircraft owner. The difficulties encountered in renting aircraft -- aircraft being returned late by previous renter, not topped off with fuel, equipment not working, flat spots on tires, chewing gum wrappers and dirty styrofoam cups left in seatback pockets, etc. -- will be relagated to the distant past when you own your own aircraft. But, like most things in life, there's a tradeoff. Becoming an aircraft owner brings on a whole new set of responsibilities, and these are the focus of Irv Siegel's latest interactive quiz.

Quiz #24 -- Cold-Weather Flying

Cold-weather flying requires a specialized set of pilot skills and knowledge in order to be accomplished safely. Just as you wouldn't drive your car in severe winter weather without the proper preparation, the same is true for flying an aircraft under such conditions. Try your hand at Irv Siegel's latest interactive quiz and see if you're ready to tackle the winter flying season.

Quiz #23 -- Speeds

Pilots are obsessed (or at least they should be) with the need for speed -- not necessarily the most speed, but the appropriate speed. For virtually every aspect of flight, there's a particular speed that's optimum. Going faster or slower than the optimum speed may be inefficient, unsafe, or even deadly. Irv Siegel's latest interactive quiz poses a variety of situations wherein the pilot has to choose the correct speed at which to operate or on which to base certain calculations. Are you up to speed?

Quiz #22 -- Emergencies

Flying is easy when everything goes as planned. It's how we react when something unexpected happens that separates great pilots from the not-so-great. What would you do if your engine started losing power? If your oil pressure suddenly dropped to zero? If you found yourself low on fuel? If you lost an engine in a twin? If you inadvertantly entered IMC while flying VFR at night? Irv Siegel's latest interactive quiz challenges you to think about how you'd handle these and other emergency situations.

Quiz #21 -- Operation at Non-Towered Airports

Non-pilots often believe that a non-towered airport is inherently unsafe, and many pilots who do most of their flying at airports with operating control towers are uncomfortable when flying in or out of non-towered fields. Even pilots who have extensive experience operating at non-towered airports have picked up bad habits over the years. Regardless of your experience at non-towered airports, Irv Siegel's latest interactive quiz is sure to get you thinking about good operating practices at such airports.

Quiz #20 -- Night Flying

In the United States and many other parts of the world, autumn is a lovely season for flying. The foliage is changing color, creating spectacular scenery, and the weather is generally pleasant. But autumn also brings dwindling daylight hours and more hours of darkness. A flight that ended in daylight during summer might now mean a landing after dark. In case you're a little rusty on the finer points of flying at night, this interactive quiz should provide an educational brush-up.

Quiz #19 -- Airman Medical Certification

You passed your last aviation medical exam with flying colors. But now, your family physician tells you that you've got a medical problem of some kind. Perhaps your blood pressure is higher than it should be, or your blood sugar is a bit elevated, or you passed a kidney stone. How does this affect your FAA medical certificate? Irv Siegel's interactive quiz covers these and other medical certification questions that every airman should be able to answer. Can you?

Quiz #18 -- Operating at Tower-Controlled Airports

Whenever you fly into or out of an airport with an operating control tower, your every move and transmission is under the FAA microscope. Better know the rules, or you risk getting that dreaded request to "phone the tower." Pretty confident you know your stuff? Try taking this interactive quiz and find out for sure!

Quiz #17 -- FAA Compliance and Enforcement Policy

Whether you're a pilot, a mechanic, an airline executive or another sort of certificate holder governed by the Federal Aviation Regulations, at some point you'll probably come in contact with a man in a white shirt and skinny tie, wearing a blue nametag and a benign smile that says "I'm here to help." In case you were wondering, he's an FAA inspector and his actions are governed by the FAA's very complex Compliance and Enforcement Policy. How much do you know the rules that he plays by? Take this quiz and find out. Bet you'll be surprised at what you learn!

Quiz #16 -- Pilot Weather Reports (PIREPs)

Forecasts are fine and dandy, but the only really reliable information we have to go on about weather hazards like icing, turbulence and windshear are the PIREPs we get from pilots who flew there before us. Do you file PIREPs as often as you should? Do you even know the correct procedures? Take this quiz and find out.

Quiz #15 -- Aeronautical Lighting

Flying at night is one of the most enjoyable aspects of aviation...but do you know the meaning of all those colored and flashing lights down there? Clean the cobwebs off your mouse and find out.

Quiz #14 -- FAR Part 61

On August 4th, 1997, a massive rewrite of Part 61 of the Federal Aviation Regulations went into effect, governing the certification of pilots, flight instructors and ground instructors. All U.S. pilots need to be up-to-speed on these regs, and CFI had better know them by heart. But for you non-CFIs, this quiz is open-book: we provide links to the text of the new rules. Okay, class, let's see if you've been paying attention.

Quiz #13 -- Maintenance Regulations

This quiz focuses on FAR Part 43, the rules and regs affecting aircraft maintenance. Yes, pilots and particularly aircraft owners are supposed to know this stuff. But do you?

Quiz #12 -- Basic Regulations

Many of our Brainteasers have focused heavily on IFR-related topics, and we've had many requests for quizzes that would be more appropriate for non-instrument rated Private and Student pilots. So this time, we'll take a look at some of the most basic FARs from Part 61 (pilot certification) and Part 91 (flight rules) that every pilot should know. Let's see how much you've forgotten since your last BFR oral. (Instrument pilots, ATPs and CFIs will find this quiz challenging, too.)

Quiz #11 -- Terrestrial Navaids

With all the emphasis on satellite-based navigation these days, discussions of those 1950's technology groundbound anachronisms -- VOR, DME and ILS -- may seem passe. But since we're going to be living with them for at least another decade, let's see how much you remember about these soon-to-be-nostalgic navaids.

Quiz #10 -- Radio Communications

When you key up that transmitter to talk to ATC or FSS, do you sound like a pro...or a "lid"? (That's controllerspeak for a pilot who has bad radio procedure.) The use of standard phraseology and proper radio communications techniques is what distinguishes the professional-sounding pilot. So let's see just how well you know how to "talk the talk."

Quiz #9 -- Holding Procedures

From our Not-So-Useful-Information-But-You-Oughta-Know-This-Anyway file, here's an interactive quiz about IFR holding procedures. The problem with holding is that most of us don't do enough of it to stay current on the procedures. But sooner or later, if yoy fly much real-world IFR, you'll get a hold or two. This quiz appears in abbreviated form in the August 1996 issue of IFR magazine.

Quiz #8 -- METAR

Starting July 1st, 1996, those old familiar SAs and FTs were replaced by strange-looking mumbo-jumbo called METARs and TAFs. This quiz will give you a pretty good idea of whether or not you've mastered the transition to METAR-format reports.

Quiz #7 -- Airspeed Indicators

The February 1996 crash of a 757 off the Dominican coast appreas to have been caused by a faulty airspeed indicator. In this quiz, which appears in abbreviated form in the May 1996 issue of IFR magazine;, we take a look at ASIs and find out how well you understand these most taken-for-granted of cockpit instruments.

Quiz #6 -- Class D Airspace

In this quiz, which appears in abbreviated form in the April 1996 issue of IFR magazine, we'll take a look at Class D airspace, those odd little circles that surround most towered airports. Let's see how well you understand what they mean.

Quiz #5 -- Airport Signs

One of the most significant changes at U.S. airports in recent years has been the new system of standardized signs. They can be tremendously helpful to pilots at unfamiliar airports and in low-visibility conditions...but only if you have a good understanding of what the new signs mean. Do you?

Quiz #4 -- Logging Time

Whether you're a neophyte student or grizzled old IFR pro, you need to know how to answer questions concerning logging of flight time. In this quiz, IFR magazine editor Paul Bertorelli tests your understanding of some of the basic concepts and legalities of logging.

Quiz #3 -- Transponders

How well do you know the rules and requirements for transponders? A number of these rules have changed in recent years...have you kept up? Take a stab at answering these questions from the November 1995 issue of IFR.

Quiz #2 -- Procedures

IFR flying involves more than just keeping the needles centered. It also requires judgment tempered by a thorough knowledge of the FARs and accepted procedures. We dare you to take a whack at this month's questions from IFR magazine editor Paul Bertorelli.

Quiz #1 -- BWI ILS 15R

Match wits with IFR magazine editor Paul Bertorelli as he puts your approach plate reading skills to the test. Paul is infamous for his tough and tricky questions, some of which just don't have pat answers. Not for the faint of heart. This month's challenge: the ILS 15R at Baltimore-Washington International.
