As altitude increases, the indicated airspeed at which a given airplane stalls in a particular configuration will
A
decrease as the true airspeed decreases.
B
decrease as the true airspeed increases.
C
remain the same regardless of altitude.✓ Correct Answer
Explanation
A wing stalls at a given angle of attack, and the airspeed indicator measures dynamic pressure, which is what determines lift. So for the same weight and configuration the indicated stall speed stays essentially the same at any altitude, while the true airspeed at the stall increases with altitude.
