Which flight condition is affected by wing washout?

Wing washout refers to the intentional reduction of wing angle of incidence from the root to the tip of the wing. This design feature plays a significant role in enhancing low-speed stability. When an aircraft is flying at lower speeds, the wing experiences stall phenomena, which can lead to loss of control if not properly managed. By incorporating washout, the root of the wing stalls before the tip. This design helps preserve aileron effectiveness and directional control, allowing the pilot to maintain better control of the aircraft during low-speed maneuvers.

In terms of the other flight conditions, while wing washout can have some influence on aerodynamic efficiency and load factors, its primary purpose revolves around enhancing stability, particularly at low speeds. This feature serves to improve the overall safety of the aircraft during phases of flight where stall margins are critical, such as takeoff and landing. Therefore, the significance of wing washout in relation to low-speed stability is crucial for safe aircraft operation.
