I was given an endorsement for "high performance"
...but it was in a 200HP RG, and December 1991
Some years later getting checked out for rental ...and I can't remember if it was for the 182 or 172RG (don't remember which, maybe it was both times). When they signed me off ok to rent I asked for the proper endorsement (HP for the 182, or complex for the RG) but the instructor argued I didn't need it. Even got the chief instructor involved. I was surprised they wouldn't do it. Even if it was a duplicate, so what? At that point in time I'd logged a fair little bit of complex time, multi dual, even signed off to solo the complex muti engine...but don't think I had any real >200HP high performance at that point....and probably logged dual/PIC but no solo PIC complex time.
I did ultimately go on to log time in the 230HP 182, "solo PIC"....
& I have complex time in several types
....but this still bugs me
I think it was complicated for a few reasons
early on my log book listed "complex" time but didn't have a column for High performance
& in hind site looking back either me or the instructor might not necessarily know how many HP was in some airplane years ago at some other flight school....
now with the internet we can look these things up with so much more certainty, and we can also dissect these nuanced regulations so much more easily now.... such as 200HP or greater than 200HP
my 2 cents.... get the endorsement if you have the opportunity. It's fun to collect ratings, types, endorsements, etc...
