What is the minimum safe airspeed in the yellow arc?

• A. 100 KIAS
• B. 111 KIAS
• C. 120 KIAS
• D. 130 KIAS

Answer: (B)

The minimum safe airspeed in the yellow arc, which represents the cautionary range on the airspeed indicator, is indeed 111 KIAS. This airspeed is crucial as it provides a buffer above stall speed and indicates that the aircraft is operating in a range where normal handling can be maintained, but caution is advised due to potential turbulence or loss of control. Operating within the yellow arc means that the pilot needs to be aware of their surroundings and the aircraft's performance, as flying at this speed could lead to undesirable flight characteristics if not managed correctly. It acts as a threshold where the pilot must pay extra attention, especially in the presence of environmental factors such as wind or weather conditions that could affect aircraft performance. The other choices present airspeeds that exceed the cautionary range but do not define the minimum safe airspeed effectively for operations in the yellow arc. The designated airspeed of 111 KIAS thus serves as a critical reference for safe maneuvering and awareness in varying flight conditions.
