It does happen though, does it not?

Nope! In a GA airplane operating from a "hot-high' airport, you
simply don't have rated T.O. power available. In a jet transport,
you simply move the thrust levers forward some more to make-up for
the "hot-high" conditions. In the 50's era Navy jets that I flew,
full throttle was T.O. thrust, but then, they never flew from "hot-
high" airports, and if they did, they could not develope the engine's
rated T.O. thrust.
