Experience
200 hours jet or 20,000 hours jet. safe or unsafe.
In my opinion, you are only the top gun of the airline world when you are competant enough to aileron role a cessna 152 at 100 knots.......YES, THAT'S RIGHT 100 KNOTS!!!!
Raw power from that 105 or 130 (RR engine) that can excite and terrify at the same time.
The 152 - A man's machine, not for the faint of heart or the medically confused.
