I am sorry if my comment seemed arrogant but it is a fact. A current SEP pilot should be able to fly any other similar SEP with little effort.
As certified aircraft they all fly inside a similar envelope and a current pilot should not have a problem learning the subtle differences in a very short period of time. I have just this minute come back from being checked out in a PA32.
Checkout was:
Standard landing, short field landing, flapless landing.
Stall, clean, and turning with gear out and final config.
Speeds and power settings were talked through as we went along and were pretty much standard. Gear up back to 25/25 cruise 23/23, lean. I worked out where the fuel pumps, emergency gear release and landing lights etc were and what all the buttons did from being a CURRENT SEP/MEP pilot.
All in all we were brakes to brakes 30 minutes. It really is not rocket science.
