Hi CB,
I beg to differ from that statement, without wishing to start an argument. IIRC, stall speed is a function of:
Agreed, but you have changed the context of the statement by trying to capture the variable of the stall speed. What I am saying is that the stall speed may change for environmental, weight, wing loading,what have you, reasons. But the stall still only starts at the critical alpha.
Basically, for any wing configuration (flap, slat, etc setting) there is only one cirical alpha. The aircraft will only be in a stalled condition if that AoA is exceeded regardless of the speed (EAS) it maybe travelling at.
Icing is unquantifiable. Yes, it will change the wing shape (configuration) and add weight so both the stall speed and the critical alpha will almost certainly change for the worse. For any given situation that is all we know. But, even under those circunstances, this wing will still only start the stall at the critical alpha (whatever it maybe) regardless of speed.
