higher angle of attack which translates to a higher stall speed
Does it?
My understanding is that a change in stall speed is affected by a change in weight (and therefore G loading) with all other things (configuration) being equal. If you have a wing at a higher angle of attack, it might be
closer to stalling in terms of slowing down faster, and perhaps likely to stall before the other wing is things are not symetrical, but not at a higher speed.
Correct me if I'm wrong, but the stall speed for a 1.5 G wings level pull up, during which we will presume that both wings stalled at the same time, will be the same speed as a stall in a turn (climbing dscending not a factor) at 1.5G. Just in the 1.5G turn there is a possiblity of the outer wing stallling before the inner - yet at the same speed as the pullup.
If the wings do not stall together, the first wing to stall, will define the stall as having happened, and the speed can be observed.
Happily, my experiences testing for 23.203 Accelerated turning stalls, in single and multi types up to Cheyenne, King Air and Twin Otter have never shown me a wing drop of any concern for the 30 degree bank turn requirement. Slight increase in speeds, but only attributed to the spightly increased G.
