And can someone tell me if you do full shut downs on piston engine airplanes in the winter? And if so has anyone come up with a minimum temperature where you think this would be prudent?
I am with you in wanting to shut engines down as rarely as legally possible.
However, in answer to your last question it is not avoidable on CofA renewal and therefore I did do so last week in the bitter cold (-4 on the ground, -10 at shutdown altitude.)
Is your concern that the engine will get very cold rather quickly, hence the risk of cracks, or that the oil will get rather thick rather quickly and possibly not flow adequately in the CSU?
or maybe something else I hadn't thought of?
