摘要

Long before I became a pilot, I read something somewhere about the extreme : dangers of shock cooling a piston aircraft engine. The article didn't spec-ify which engines. It tossed a large, wet blanket over every Lycoming and Continental ever made. The idea of cylinders cracking on a steep descent with all that cold air passing over them captured my imagination. It wasn't until years later that the myth was finally debunked. Think of how many thousands of times a student pilot chops the power in a trainer and comes down at idle for a simulated engine out. That's not to say shock cooling isn't an issue for some engines, but it isn't for the vast majority of the aircraft we fly. What began as a precautionary procedure for a small number of high-performance engines has needlessly trickled down to populate the Zeitgeist.
