What is the purpose of the stall warning system in the Warrior PA-28A?

The stall warning system in the Warrior PA-28A is specifically designed to alert the pilot of an impending stall, which is crucial for maintaining safe flight. When the aircraft approaches the critical angle of attack, where airflow over the wings begins to separate and lift diminishes, the stall warning system activates. This helps the pilot to take corrective action—such as reducing the angle of attack or adding power—to prevent the stall from occurring.

Understanding that stalls can lead to loss of control, the stall warning system plays a vital role in flight safety by providing timely warnings. This system allows pilots to be proactive rather than reactive, thus enhancing their ability to manage the aircraft effectively during critical phases of flight, especially during takeoff and landing.

The other options, while relating to aircraft systems, do not serve the specific purpose of stall detection and prevention, which is the primary function of the stall warning system.
