A lot of talk about GA, most can do this OK from normal GA height, it is when you do this from height it catches people out - try it in the sim with a level off at 2,000' and given the GA at 1600' or even worse 2,100', it will catch many out who think they know how to do it!
foxmouth, agree - so it needs to be specifically taught and practised on a regular basis then, as I'm sure you know.
