Dad babied his cherished Skylane. He never let me fly it solo. (He did endorse my log book for ‘high performance’ aircraft.) One thing he made certain of was not to ‘shock cool’ the engine. That is, he didn’t want the engine temperature to come down to quickly and result in a stuck valve or cracked cylinder.
The Wikipedia article says there is controversy about shock cooling, and many consider it a myth. It’s been a quarter century since I flew the 182, and I don’t remember the descent procedure to prevent shock cooling (if it exists). I remember slow reduction of the throttle, carb heat on, and cowl flaps closed.
Can someone remind me of the procedures?
(And no, I’m not going to rent a Skylane. If I were, I’d receive instruction at the time. )
