What is the stall warning system in the Pilatus PC-12 NG designed to do?

The stall warning system in the Pilatus PC-12 NG is specifically designed to alert the pilot to an impending stall condition. This system plays a critical role in flight safety by providing timely alerts when the aircraft is approaching a stall, which occurs when the angle of attack exceeds a certain threshold that disrupts the smooth airflow over the wings. By warning the pilot of this condition, the stall warning system allows for timely corrective actions to be taken, such as reducing the angle of attack or increasing power, thus preventing an actual stall from occurring.

This focus on stall prevention is crucial because stalling can lead to loss of control if not addressed promptly. Unlike other systems in the aircraft, which monitor engine performance, fuel levels, or cockpit lighting, the stall warning system is uniquely tailored to enhance pilot awareness of aerodynamic limits, making it essential for safe operation during various phases of flight.
