A few months ago I tried to see how high I could go. My plane is a
C172 with 180hp Airplains conversion. Just my wife and me aboard. I
was still climbing at 15,750 msl, but quit since I then needed to
descend at a reasonable rate to land. Nice cool day here in
southcentral Montana. I was still getting a reliable 200'/min climb.

When you gonna get a real hangar and stop letting Corporate Air leave
your plane out all day?
