Factors Affecting Stall Speed

QUOTE]I know that the stall speeds vary due to altitude, gross weight, configuration and bank angle and the only way an airplane can stall is by exceeding the CLmax angle-of-attack. [/QUOTE]


I'm suprised noone addressed this, but I'm sure that the stall speed doesn't change with altitude. I have all my books packed away, but if you look in the Trevor Thom Private and Commercial book it will say the same thing. It will also be addressed in most multi-engine books.

The TAS of the stall will change with altitude but not the IAS or CAS. Is that what you ment? Or did you mean out of ground effect?

Correct

ksu_aviator,

You're correct. For practical purposes, the stall IAS remains the same at all altitudes. The IAS varies slightly due to airflow changes in airplane attitude, configuration and proximity to the ground (ground effect). This variation is called position error and each airplane flight manual has correction charts to obtain CAS. Thanks for keeping everyone straight on this. Fly safe.
