Vso speed is defined as?

• A. Maneuvering speed
• B. Maximum operating limit speed
• C. Approach speed
• D. Aircraft stalling speed

Answer: (D)

Vso is the stall speed in the landing configuration. This means the minimum steady speed at which the airplane can fly with the landing gear down and flaps in the landing position before the wing stalls. Flaps extended increase lift, allowing the aircraft to maintain level flight at a lower speed, so the stall speed in this configuration is specific to landing. This is crucial during approach and landing because flying below this speed risks an imminent stall with the gear and flaps extended. Other options describe different speeds—maneuvering speed relates to structural limits during control input, maximum operating speed to the high end of the speed envelope, approach speed is a practical landing speed but not a formal V-speed, and a general stall speed would refer to clean configuration rather than landing configuration.
