The white arc on the airspeed indicator represents the flap operating range of the aircraft. This range indicates the speeds at which the aircraft can safely deploy flaps, allowing for better control and reduced stall speed during slower flight configurations. Knowing this range is crucial for pilots as it helps in determining the appropriate airspeeds for landing and takeoff when flaps are being utilized. Operating within this range ensures safe handling characteristics and compliance with the aircraft's aerodynamic limits while using flaps.
