The RAF used to teach turnback, one of the reasons they stopped teaching it is because more ppl were injured practicing (with a good engine) Than needed to attempt it for real.
If most RAF pilots fail even with a good engine, then attempting to do it with no engine should be a last resort.
Of course the best thing to do is PPPPPPP. PLAN for it, self brief before TO then you will have most of the information at hand when it happens.
I have posted this before.
I was chatting with an old bold pilot and the subject of EFATO came up. "It said it must come as a shock when the engine fails". His reply " No I always expect it to fail, in fact it comes as a nice suprise when the damn things stay running".
I suspect he self brifed for engine failure before every TO. He was a Mosquito pilot in WW11 in his early 20s.
