I see my posting was not clear. My story tried to illustrate that a "cockpit checkout" is not well defined, and in the case of that specific CFIG, was completely misunderstood. For a useful checkout, a non-CFI pilot who is well acquainted with the model can probably do a better job than a CFI who is not.

When I got my first glider, which was an HP-14, single-seater with flaps and no spoilers, I got checked out by a CFIG in a *Cessna*, which was appropriate, since that allowed dual practice with flaps. I was also used to flying the Cessna at that time, so could demonstrate knowledge and proficiency in the use of flaps. I wonder if a powered plane (with a suitably rated CFIG) could be used for dual training for the motorglider endorsement, if a 2-seat motorglider is not available?
