When does the stick shaker activate in relation to a stall?

The stick shaker activates as a warning system designed to alert pilots of an impending stall condition. It typically engages when the aircraft is approaching a critical angle of attack, which is approximately 5-10 knots prior to reaching the actual stall speed. This pre-stall warning provides pilots with crucial time to respond and take corrective action to regain control and avoid entering a stall.

The choice stating 5-10 knots prior to stall is accurate because it aligns with the operational parameters for many aircraft, allowing for a safe threshold to recognize the stall risk. Understanding the timing of the stick shaker activation is essential for effective stall recognition and recovery techniques in flight training and operational procedures.
