What is the maximum flap extended speed (Vfe) in KIAS?

The maximum flap extended speed (Vfe) represents the maximum airspeed at which the flaps can be safely deployed without risking structural damage or compromising the aircraft's performance. In the context of this question, the correct answer of 111 KIAS corresponds to the specific aircraft model being referenced, which typically has its Vfe specified in the Pilot's Operating Handbook (POH).

This speed is crucial during different phases of flight, particularly during approach and landing, where flaps are utilized to increase lift at lower airspeeds. Knowing Vfe helps pilots avoid exceeding this limit, which can lead to flap damage or increased drag and stall risk in case of a go-around or if additional lift is required.

The other values provided do not represent the correct Vfe limit for the specific aircraft in question. Each aircraft has its own unique operating limitations outlined in the POH, which includes Vfe among other critical speeds. It's essential for pilots to know these limits to ensure safety during flight operations.
