What happens when the stall warning system activates?

When the stall warning system activates, it provides an alert that the aircraft is approaching a stall condition. This system is critical for flight safety as it alerts the pilot to an impending stall, which occurs when the aircraft exceeds its critical angle of attack, leading to a loss of lift.

The stall warning is typically signaled through an audible alarm and/or a visual indicator. These alerts enable the pilot to take corrective action, such as reducing the angle of attack or adding power, to prevent the stall from occurring. Understanding this response is essential for pilots to maintain control of the aircraft and make timely decisions to ensure safety.

The other options do not relate to the function of the stall warning system. For instance, activating the landing gear or increasing engine power automatically are not actions associated with the stall warning; instead, they address different operational parts of the aircraft. Similarly, a successful takeoff is not connected to stall warnings but rather relates to the aircraft achieving safe flight after leaving the runway.
