Firstly, if I'm teaching/examining steep turns I'll damn well make sure a HASELL/HELL check is done, normally by myself.
Funny about all these strange and sometimes quite hilarious mnemonics- most of which I have never heard of; although to some it is fun inventing new ones. We are required to demonstrate steep turns in the instrument rating test in a Boeing 737 full flight simulator. Does that means we must do a HASELL check first? I am sure our Examiners would laugh you out of the simulator. Incidentally, pray what exactly is a HASELL check?
One check taught to me by a young and inexperienced instructor who invented it, was a short final check in a Cessna 150. It was PPUFF checks on final. It stood for Prop Pitch Control not applicable. Power Poles (Now that is a case for TEM!). Undercarriage Fixed therefore not applicable. Flaps. Feathered Friends. (TEM, again which included which way to turn/descend/climb) if a bird come s your way
