What is the purpose of the stall warning system?

The stall warning system is specifically designed to alert the pilot as the aircraft approaches a stall condition. A stall occurs when the airflow over the wings is disrupted, leading to a loss of lift and control. This warning system provides early indication, often through audio or visual signals, allowing the pilot to take corrective action before the stall actually occurs. It is an essential safety feature that helps prevent loss of control during flight, particularly during critical phases such as takeoff and landing when the aircraft is more likely to approach stall conditions. Other options, such as indicating an upcoming descent, providing navigation updates, or measuring fuel levels, do not relate to the primary function of the stall warning system, which is focused solely on preventing stalls to enhance flight safety.
