A friend of mine's IFR instructor showed him something I've never heard of.
He rolled in 2 - 3 turns of nose up trim on our 172, pushed on a rudder
pedal, and went into a nice level steep turn without touching the yoke. I'm
not sure if this is practice for proper turn entry or a way of entering an
emergency turn partial panel without the danger of over banking.

Can anyone shed further light on this maneuver?
