Excellent discussion.
From my Jet Provost instructor days I can remember preaching that it could be a dangerous practice to increase the AOB when turning finals to regain the extended centre line, after flying through it for some reason, when the airspeed is low.
Because of the dihedral on the JP, the down going wing would have the AOA increased and despite the negating aileron effect at reducing the AOA on that portion of the wing in front of the aileron and the washout, the rest of the low wing could stall.
Full power, unload and when out of the buffet roll the wings level and start the climb as gently as the distance from you and the ground will allow.
Even in a steady rate turn I think the lower wing have the AOA increased due to the sideslip and hence having a greater reason to stall first? Which is possibly the worst case scenario.
Demonstrating this effect at height often lead into an incipient spin and great fun.......and a salutary lesson applicable to every type of aircraft.
