I recall reading that General Yeager was able to withstand operating at 20,000' without oxygen. Nearly all of the pilots in the Great War could. Only some of the German aircraft had oxygen systems, and I've not heard of any Allied aircraft that did. Ceiling on the S.P.A.D. was 6,000 meters, according to Nordhoff and Hall.

I must have missed OSH that year. I would really like to see the AN225 and
have always liked the *biggest* anything. Anyway, you might show this: http://www.metal-club.org/12-Cylinder.html to your mechanic for his new boat.

Jay, you could put your Pathfinder (full fuel, four 200lb people and baggage), AND the Mighty Grape, AND your motel inside and bring the lot to OSH where you could probably get a lot more for your aviation suites. Yeah, I saw that monster a few years ago -- I think at OSH? It was parked nose-to-nose with our own C-5 Galaxy -- quite a sight! -- Jay Honeck Iowa City, IA Pathfinder N56993 www.AlexisParkInn.com "Your Aviation Destination" |

wrote in Message-Id: .net: I suspect that the 182's shorter landing performance has more to do with its better flaps and consequent lower approach speed than with ground effect. The PA28's flaps are considerably closer to the pavement than the Cessna's. That might increase ground effect. I agree, that a heaver load at a higher speed is a significant contributor to the PA28's longer landing run also. Perhaps there are errors in the specifications posted: john smith wrote in Message-Id: : keeping in mind that these are 1974 models...
