I'm teaching people to fly heavy jet transport aircraft. The rudder is powerful, but the aircraft has much inertia. This tends to lead to over-controlling by newer pilots in the early stages. A lot of training happens in the sim with poor visibility conditions. I can explain all of this in long flowing sentences, then sum it up with "squeeze and freeze" as a handy reminder.
"Aviate, navigate, communicate" will always be a firm favourite.
TangoAlphaD, I like it.
