1. Unloading the wing (stop pulling or trimming back thereby reducing the AOA to a low value well below the stalling angle) only then
2. Use rudder to get the ball roughly centre after which use aileron to level the wings
Agree with Note 1 but a bit concerned about Note 2 (using rudder to centre the skid ball during a UA recovery) The Boeing 737 FCTM recommends unloading while
simultaneously using up to full aileron to level the wings.
After all, the act of unloading gives immediate better aileron control. Using rudder to centre the skid ball in a jet transport gives a strong yawing moment which is not desirable since is leads to a roll.
According to the 737 FCTM the only time you would consider applying rudder is if a very nose high, rapidly decreasing speed situation has occurred. The FCTM states:
"A nose high, high angle of bank upset requires deliberate flight control inputs. A large bank angle is helpful in reducing excessively high pitch attitudes. The pilot must apply nose-down elevator and adjust the bank angle to achieve the desired rate of pitch reduction while considering energy management.
Once the pitch attitude has been reduced to the desired level, it is necessary only to reduce the bank angle, ensure that sufficient airspeed has been achieved, and return to level flight.
If full roll control application is not satisfactory, it may be even necessary to apply some rudder in the direction of the desired roll. Only a small amount of rudder is needed. Too much rudder applied too quickly or held too long may result in loss of lateral and directional control or structural failure.'
I wouldn't be too keen on risking structural failure if the rudder was mis-used during the attempted recovery. Using the rudder to place the skid ball roughly central, before using aileron, might be chancing your arm.
Then again it may all depend on the aircraft type.
