Which color identifies the power-off stalling speed with wing flaps and landing gear in the landing configuration?

The power-off stalling speed with wing flaps and landing gear in the landing configuration is identified by the lower limit of the white arc on the airspeed indicator. The white arc represents the airspeed range for flap operation, indicating safe speeds when the flaps are deployed.

Specifically, the lower limit of this arc marks the stall speed in a landing configuration, which is crucial for pilots to know when approaching for landing. At this point, the aircraft is at its lowest controllable speed with flaps extended, making this information vital for safe landings. Understanding the white arc and its significance helps pilots manage airspeed during critical phases of flight, particularly when preparing to land.
