Shock cooling has been done to death in every pilot forum, airport bar, aviation magazine, Usenet, engine manufacturer's literature
Oh ok, I won't ask then
I've been reading up on this for a while now but, as you say, I can't find any definative information. I just want to know the best action to carry out when the EDM starts flashing at me. Ignore it? keep power on to help stem the cooling? use a shallower descent?
Where did Lycoming get the -50 figure from? Why does the EDM display the CLD so prominently? Is it a gimic? Too many questions.
With regard to glider tugs, I believe our pilots carry out a high power descent and approach to be kinder to the pistons.
