During the AOA test, at what degrees AOA does the stick shaker activate?

The stick shaker is a critical safety feature that provides tactile feedback to the pilot, indicating that the aircraft is approaching a stall condition. The activation of the stick shaker is typically calibrated to activate within a specific range of Angle of Attack (AOA) values.

In this case, the correct response indicates that the stick shaker activates at AOAs of 0.4 to 0.5 and again at 0.7. This range is designed to alert the pilot to reduce the pitch and avoid entering a stall. The stick shaker serves as an early warning system, allowing the pilot time to respond and recover from an impending stall.

The chosen answer reflects an understanding of the importance of the AOA in flight safety, ensuring that pilots maintain awareness of the aircraft's aerodynamic limits. Recognizing and responding to the stick shaker can enhance pilot decision-making and aircraft control during critical flight phases.
