Final answer:
The flap operating range is depicted by a white arc on the Airspeed Indicator (ASI), extending from the minimum speed with flaps extended (Vs0) to the maximum flap extended speed (Vfe).
Step-by-step explanation:
The flap operating range on the Airspeed Indicator (ASI) in aviation is typically depicted by a white arc. This white arc starts at the lower limit, the minimum speed with flaps extended (Vs0), and extends to the upper limit, which is the maximum flap extended speed (Vfe). When operating an aircraft, it is crucial not to exceed the Vfe as doing so could cause damage to the aircraft's flaps. Pilots must be aware of the correct speeds indicated on their ASI and operate the flaps within this range during takeoff, landing, and specific in-flight maneuvers.
