Diesel wasn't a slam dunk in 1928 and for some of the same reasons, it still isn't.

2) Cirrus' New Turbo: Baffling - (Jun 23 2010)

Cirrus owners are normally gleeful about new models. Not this time.

3) Analyst Sees 8900 New Bizjets By 2020 - (Feb 16 2010)

Business aviation analyst Brian Foley has taken a cue from the judging protocols of some sports competitions in determining that, overall, business jet sales will grow at 2.7 percent over the next 10 years. Foley tossed out the results of bizav's best year in recent memory (2008) and one of it's worst (2009) to come up with figures he thinks will stand up and actually mean something for those making plans for the next decade. "2009 was too unsettled and 2008 was a clear anomaly, an unsustainable peak," Foley said. "Our same numbers would yield a minus growth -2.6 percent if measured against 2008, but that's not really useful information." Foley predicts 8900 business jets worth $170 billion will be built between now and 2020. Foley has also tried to forecast bizjet fuel consumption and, if he's correct, there will be a significant increase in the use of private aviation.

4) TCM'S Turbo And Fuel Initiative - (Jul 26 2009)

When Teledyne Continental said it wanted to prove that high-performance engines could operate on unleaded fuel a few months back, it generated some doubting glances. But at AirVenture on Sunday it proved it was serious by flying into Oshkosh a turbocharged Cirrus SR22 tankered with what will eventually become 94UL aviation fuel. Think of 94UL as just like regular avgas, minus the lead. It's not certified yet nor is the airplane approved to use it, so when Continental lead engineer Keith Chatten gave us a brief demo in the airplane Sunday, we got a look at a test ship. Because 94UL is still a boutique fuel and not available for distribution, our flight trial was on 100LL. The fuel does meet ASTM specs, however.

5) TCM Tackles the Fuel Problem - (Apr 1 2009)

For nearly three decades we've been writing stories about the difficult struggle to find an octane enhancer as good as lead, and now here comes TCM to say, well, never mind. It reminds me of that classic headline about World War I: "Archduke Found Alive; War a Mistake."

6) How's Your Turbo-Normalized Cirrus SR22 Working Out? - (Nov 23 2008)

Our sister publication, Aviation Consumer, would like to know. The magazine is conducting a survey of owners on their experiences running the SR22's engine lean of peak. If you'd like to participate, contact the editor directly at avconsumer@comcast.net.

Kitplanes Editor-in-Chief Marc Cook checks in with JPI vice president Larry Elbert. As it turns out, the company has a lot going on, especially for those of you running lean of peak. This podcast is brought to you by Bose Corporation's Aviation Headset X™.

8) Why Don't You Have an Engine Monitor? - (Sep 19 2008)

Why Don't You Have an Engine Monitor: In the era of $6 and higher gas, there's no reason not to have one of these devices. It will help with leaning and provide all-important engine maintenance cues. Read all about monitors in this article from Light Plane Maintenance.

9) EGT and CHT Interpretation - (Sep 18 2008)

We go beyond the basics in this article on getting the most out of your digital engine-monitor system.

10) Here Are the Details: Lycoming's New FADEC - (Aug 1 2008)

Lycoming showed AirVenture 2008 that it's bullish on the light aircraft market by unveiling a new variant of the popular O-540 series, the TEO-540-A, a 350-horspower engine with a full authority digital engine control, the second such certified system for piston engines to hit the market. Lycoming's Mike Kraft told AVweb that the new engine will appear first in the piston version of the Lancair Evolution but the company has its eyes on the certified market with an introduction next year. What's special here? Fuel is provided by an automotive timed pulse design rather than a manifold/air mass fuel injection system and each cylinder has its own closed-loop power control. Unique to the TEO-540 is automotive-style knock sensing for each cylinder which should help the engine adjust to what Lycoming sees as an inevitable decline in the availability of high-octane aviation gasoline.

11) The Savvy Aviator #59: EGT, CHT and Leaning - (Jul 3 2008)

Why does proper leaning procedure seem to be such a confusing subject for pilots when it's so darn easy?

12) Recalling the Big One: Not WW II, The Great Leaning War - (Jun 4 2008)

Here's an amazing number: Merely by operating engines lean of peak, aircraft owners are saving themselves more than $30 million a year. That's a big number. Will Lycoming ever embrace the idea?

13) Leading Edge #17: Having a Say in Fuel Costs - (Apr 28 2008)

With skyrocketing fuel costs, pilots are flying less or sometimes not at all. AVweb's Thomas P. Turner has good fuel-sipping suggestions that won't compromise safety.

14) The Savvy Aviator #56: Before You Yank That Jug ... - (Apr 10 2008)

Your aircraft is undergoing its annual inspection, and your IA tells you that a cylinder has weak compression and has to come off. Here are some things to consider before you tell him to go ahead.

15) The Pilot's Lounge #123: A Special Airplane From Special People - (Feb 25 2008)

It's a tragedy when a pilot dies. But AVweb's Rick Durden helped turn a tragedy into an amazing gift from a grieving family.

16) Are You Wasting Avgas? - (Jan 13 2008)

Probably. But at $5 a gallon, you might want to consider an even dozen ways to reduce fuel-related costs of flying.

17) NBAA 2007: Evolving Toward an Uncertain Future - (Sep 28 2007)

As this is written, the final day of 2007's National Business Aviation Association (NBAA) Annual Meeting and convention is well underway. Tired but smiling men and women in business attire are dragging stuffed luggage throughout Atlanta's Georgia World Congress Center (GWCC), tying up loose ends and making final passes through the exhibit floor. Last-minute errands are being run, airline boarding passes gathered up and the fortunate are filing flight plans. Elsewhere, vendors and exhibitors are counting coup, toting up the products they've sold.

If your turbocharged engine runs fine down low but gets real rough up high, the problem is usually ignition-related.

19) Pelican's Perch #84: Don't Set Mixture with CHT - (Apr 3 2007)

Some pilots think the ''new wave'' in engine management is not to use EGT to set the mixture but instead to keep the CHTs under some generic maximum. Their engines won't last very long.
