How is stick shaker activation related to stall warnings?

The choice that activation occurs 5-10 knots prior to stall is correct, as the stick shaker is designed to provide a timely warning to pilots that they are approaching a stall condition. It serves as a proactive safety measure to alert the pilot that the aircraft is nearing its critical angle of attack, where an aerodynamic stall could occur.

By activating a few knots before the stall, the stick shaker allows pilots to take corrective action, such as reducing the angle of attack or increasing power, to avert entering a stall. This advance warning is crucial, as it enhances pilot awareness and provides an opportunity for the crew to respond appropriately and maintain control of the aircraft.

Understanding this relationship is essential for maintaining safety and effective flight operation, as stall warnings like the stick shaker play a vital role in preventing loss of control incidents.
