I agree with PJ2 and others that going to 5 degrees pitch is not what one would expect a seasoned pilot to do, and is not the right thing to do in the circumstances. Depending on how quickly the airplane is rotated to 5 degrees pitch, the AoA would probably temporarily exceed the stall warning threshold of about 4 degrees, and in any case the 'stabilized' AoA in still air would move closer to the stall than with 2.5 degrees pitch. On the other hand I believe, based on 'gut feeling' rather than a numerical analysis, that if CLB power had been set and attitude had increased to
but not exceeded 5 degrees pitch, that the airplane would not have stalled.
