At the critical angle the aerofoil (wing) is stalled.
Just before the critical angle I have maxLift. For a given weight = maxLift, I'm still flying level.
Now this maxLift is = 1/2 rho S V^2 Cl
Increase my weight by 20% gives me weight > maxLift.
Brings me to the conclusion that unless I increase IAS (1/2 rho V^2) I will not be able to maintain level flight. I'd say as a pilot I would call this a stall? Bearing in mind I have no power left to increase my IAS.
Yank the stick backwards and you are beyond the critical angle and the aerofoil (wing) is stalled.
So from this I will try to answer the original question...
Well maybe not, there is still a missing link somwehre
Ball in your court gentlemen, time to dig mechanics of flight
