I was just thinking about the way I first flew the different SEP types I have flown.
C150/C152 PPL in it.
PA28-180 - 2 of us went to FSO with an instructor to pick up our FAA tickets and did our bi-annual on the way there and on the way back.
PA28 slab wing trimmer on the roof. Got in and flew it.
C172- check out next time I went back to the US for hour building 45mins.
robin- got in and flew it
Katana- 1 hour in the circuit with a bloke on his FIC for his mutual. With instructions to screw with his head which I did.
Garda Horizon- maint trip with owner when the wx was pants.
PA38- 3 circuits then sent on my way for a ferry to swap aircraft for a star annual. Did some stalls and a spin or two over the vale of York on my way.
Arrow- got in and flew it.
And there were another three or 4 permit types which was just a chat with the owner before flying them somewhere.
So as such I have never done a formal differences training on any SEP type. And never scared myself either on any of them.
Never flown a MEP as PIC.
