high altitude single engine
Hi all,
me and my wife are thinking to buy a single engine airplane. We are looking to the SR-22 or the cessna 400. I was looking at their websites and both claim altitudes well above 10.000 ft. I would like to know? Are these airplane presurized in some way? or they really just on oxygen bottles? I will ask this question to them but I would like to hear from you the real story.
