A precautionary landing under power is really little different to any other landing under power albeit a slow short field approach where the big differenceEs comes into determining wind,landing area length , surface quality, slope, obstructions visible and invisible, visibility cloud base and so many other factors to a standard landing that you could almost put a great chunk of training over to that alone.
I agree. I suppose the question is whether the height you need to determine those factors is
less than you would need to execute a 180 into better weather?
