Default Stalls - Angle of Attack versus Vstall

"Andrew Sarangan" wrote in message

If the normal stall speed is 50 knots, you can make it stall at 100
knots if you pull some positive g's, or you can make it stall at 25
knots if you pull some negative g's. On the same token, you can stall
the airplane at higher or lower airspeeds depending on the aircraft
weight.


Minor nit:

Replace "some negative g's" with "less than 1g". Or "between -1 and +1 g",
if you want to get really particular.

Most wings aren't symmetrical, so it's not strictly correct to mirror the
positive and negative g numbers, but it would be more correct than the above
to say that the stall speed depends on the absolute value of the load
factor, with absolute values above 1.0 increasing the stall speed above the
published 1g number, and absolute values below 1.0 decreasing the stall
speed below the published 1g number.
