Boeing definitely recommends unloading the wings in nose high attitude upset, great technique, however, probably not in a low altitude GA in the soup.
Think about it. The pilot has stuffed up big time if during a go-around in IMC he has failed to prevent or recover from a dangerously high nose attitude accompanied by rapid airspeed bleeding back to onset of stick shaker. What are his options under these circumstances?
1. Watch the aircraft stall since his current control movements have failed to stop the speed bleed and in a few seconds he and his passengers are dead.
2. Take only some of the Boeing FCTM advice and roll the aircraft to drop the nose to permit speed gain; disregard the advice to unload to better aid recovery and instead pull back on the stick to prevent height loss near the ground.
3 Take the full Boeing FCTM advice which includes unloading the wings during the roll manoeuvre regardless of proximity of nearby terrain and hope you have acted soon enough.
Your choice. I sure know which option I would choose.
