How many knots above stall speed is the stick shaker activated?

The stick shaker is designed to provide a clear warning to the pilot that the aircraft is approaching a stall condition. It activates when the aircraft is flying at a speed that is 5 to 10 knots above the stall speed. This range is critical because it alerts the pilot in advance of reaching the stall point, allowing for timely action to recover from a potential stall, such as reducing the angle of attack or increasing airspeed. The stick shaker serves as an important safety feature that enhances situational awareness during flight operations, particularly during critical phases such as landing or takeoff where the risk of a stall might be heightened. Therefore, the correct answer reflects the operational parameters set for the stick shaker in relation to stall speed.
