My first instructor, who got me through my instrument rating back in the day, taught a simple mnemonic to remember for unusual attitude recovery. You’re in a TRAP:
T hrottle
R udder
A ileron
P itch
It has worked well for me. But after reading a recent IFR Magazine I realize it needs help. First, you need to push to unload. But PTRAP isn’t as catchy.
As for the rudder, IFR has this great disambiguation: Step on the sky, or Put your Foot in the sky. Even if the sky is just the blue part of the artificial horizon.
