Visser Spot On

I think Ben Visser was spot on in his Sept. 7 piece, The definition of insanity, when he cites the old 80/20 rule regarding 100LL use. I believe it is indeed 20% of the GA fleet, the Navajos, the Barons, the Cessna 400 series, etc., that are burning 80% of the 100LL produced. But I also believe it’s this high end of the GA fleet that is being replaced by the Caravans, the TBM-850s, the PC-12s, etc., not to mention the coming VLJs.

Success of Edge speaks for itself

In the story Wonder Woman: Patty Wagstaff Commands the Skies in the July 20 issue, writer J. Douglas Hinton asked: “We’ve noticed that some of the better known aerobatic pilots, such as Kirby Chambliss, have switched to the Edge and others, the French CAP. What’s your take on that?” Wagstaff replied: “Every airplane is a compromise. The Edge is lighter than my Extra 300, but it doesn’t have as good a roll rate. I can roll 420° per second. The other thing is a few Edges and CAPs have come apart. I just feel more comfortable in my Extra with “G” limits of plus and minus 10. It’s built like a tank but fortunately doesn’t fly like one!”

The Largest OSH Formation?

Meg Godlewski’s article in the Aug. 24 issue, Formation flight honors Van’s RVs, quoted Stu McCurdy as stating that the 35 ship RV formation flown this year was the largest ever at Oshkosh. He is not even close to correct! In 1999, the T-34 Association put up a 61-ship formation, and I am quite sure that the T-6 community has often exceeded the 35 ship RV “big one.” The picture (right) was shot through my windscreen while I was leading one of the middle elements in the 1999 Oshkosh T-34 formation. Runway 36 is visible over the nose as we made one of our arrival (from Sturgeon Bay) passes.

The same old song and dance

After receiving a sample copy of GAN, I subscribed. I have not read many aviation journals until yours arrived. My aviation career spanned more than 40 years as a captain, DPE, FBO, etc., etc. Alas, my medical is history. So I now cruise around in the cockpit of a 1953 MG.

What are financial paybacks to flight data monitoring

In the Sept, 7 issue of GAN, Meg Godlewski’s article on Flight Data Monitoring (FDM) for general aviation (Can a GA “black box” prevent accidents?) does a nice job of covering the subject. I’m the source of the “don’t call it a black box” inset, and I would like to add one more paragraph on the value proposition for the general aviation owner/pilot.

Something I can use right away

An issue or so back, Ask Paul responded to a question about a TCM O-470 (Did additive cause engine problems? Aug. 10 issue). He suggested replacing all the oil cooler hoses. Unless 470s, 520s and 550s have an add-on remote cooler, they don’t use hoses. The coolers mount directly to the engine. Supposedly, after World War II, Continental saw hoses as being prone to failure, so they mounted the coolers directly to the cases. However, I’ve seen more TCM OCs or mounting plates fail than I have hoses on Lycomings.
