How many knots above stall speed does the stick shaker activate?

The stick shaker activates when the aircraft is operating at a speed that is 5 to 10 knots above the stall speed. This range is designed to provide an adequate safety margin for the pilot to recognize an impending stall and take corrective measures. The activation of the stick shaker serves as an important alert mechanism, signaling the pilot that the aircraft is approaching a critical angle of attack where the risk of stalling increases.

Understanding the stall speed and the corresponding activation of the stick shaker is crucial for safe flight operations. It helps pilots to develop timely responses to prevent an actual stall situation. By being aware that the shaker activates at this specific speed range, pilots can better monitor their airspeed and maintain safe flight conditions.
