What is the stall speed of an aircraft?

The stall speed of an aircraft is defined as the minimum speed at which it can maintain level flight. At or below this speed, the wings of the aircraft cannot generate sufficient lift to counteract the weight of the aircraft, leading to a stall condition. Understanding stall speed is critical for pilots, as it informs them of the speed they must maintain to ensure safe flight and avoid unintentional loss of lift, which could result in a stall.

This concept is essential during takeoff, landing, and maneuvers, as flying below stall speed increases the risk of losing control. Pilots must be aware of their aircraft's stall speed under various conditions, including weight and configuration, to ensure safe operation and effective handling of the aircraft.
