Stall speed is the minimum speed at which an aircraft can maintain level flight. Below this speed, the wings cannot generate enough lift to support the weight of the aircraft, leading to a loss of control. Stall speed varies based on factors such as aircraft weight, wing design, and configuration (like flaps). Pilots must be aware of stall speed to ensure safe flying. During maneuvers, such as turns or climbs, the stall speed can increase. Understanding and recognizing stall speed helps pilots avoid dangerous situations, ensuring a safer flying experience for everyone on board.
