Hello,
That was not really my question or maybe I do not understand your answer
Why having chosen to set the maneuver speed from 2 different references:
stick shaker below 20 000ft
Low speed buffet above 20 000ft.
I know that below 20 000 ft, I have 1.3g available before stick shaker and in consequence some extra margin before reaching the stall speed.
Why did not we keep the stick shaker as a the reference for altitude higher than 20 000ft?
Do you mean that the stall speed below and above 20000 ft does not take the same parameters into acoount?
