I'm working on my reply to the ADS-B NPRM and have a question which, for the life of me, I can't figure out how to answer. It seems so simple but the usual rocks I look under don't have any data for it:
What percentage of piston powered aircraft are turbocharged?
(I'm actually looking for the percentage of the fleet that can routinely operate in the flight levels, but figure this is a close enough surrogate. And, yes, this is a current events question. <g>)
If anyone has sources or ideas I'd be most appreciative.
Regards,
Joe

Have you looked on the FAA site where the administrators fact book is? They quite often have a lot of stats broken down there. Didn't look to see if they had turbo pistons registered in the US though..

I didn't even know the administrator had a factbook! Thanks. I've looked there now, some interesting stuff. But not what I'm looking for.

I don't think that many turbocharged pistons operate at flight levels. Probably well under 1% of the overall fleet. The dual requirements of an IFR flight plan and having to breath O2 or pressurization makes is a big hassle for many owners. Add onto that the anemic climb performance of most turbocharged singles.
As a data point, even in my 340 (pressurized) I probably flew less than 10% of the time in the flight levels. With my TR182 (turbocharged 182) I only once flew above 18,000.

Back in my T210 days, I maybe spent 15-20 hours in the Flight Levels, out of 1,500 or so in the aircraft. I always thought that the airplane was much happier at 12-14,000 and so was I!

Thanks, John. They really need to update that. 4-year old avionics data? Now there's a stagnant market! Sheesh.

I called A.O.P.A. HQ and talked with a very knowledgable (veteran) there, and he said, "We don't maintain a subset of our database for this particular subject-division (obviously)... and said that your (our) best bet was with an inquiry to the FAA at OKC. He said, further, that a low relative number of "turbo A/C" would probably reside (affirmatively) in the main question [as was framed]."
Best, John
