What is the speed range indicated by the white arc on the airspeed indicator?

• A. 60-120 KIAS
• B. 35-85 KIAS
• C. 40-111 KIAS
• D. 111-149 KIAS

Answer: (B)

The white arc on the airspeed indicator represents the flap operating range for the aircraft. This range is important because it indicates the speeds at which you can safely extend or retract the flaps. For the Cessna 152, the white arc typically spans from approximately 35 knots indicated airspeed (KIAS) to 85 KIAS. This range allows pilots to make confident altitude adjustments and flap deployments without risking aircraft control or performance issues. Knowing this range helps with proper approach and landing techniques, ensuring that the aircraft is flown effectively within the limits defined by the manufacturer.
