And what about "shock cooling"? I flew a jump plane years ago, and the

always limited decent speeds and forbided complete throttle off operation.

can't remember for sure, but I think he insisted a max of 85 mph and 12"
or
so.

I've talked to sail plane tow pilots, and they climb at max power for
several minutes, and then close the throttle and dive for the ground at
Vne. If shock cooling was a real problem, they'd be losing a jug every
day.



I don't doubt it Paul. I always wondered how valid it was, expecially since
we were using a 182 with cowl flaps. But it sure delayed our decents.
