What is the airspeed defined as Vso?

• A. Stall speed in landing configuration
• B. Operating speed during departure
• C. Vortex safety operating speed
• D. Speed above stall during takeoff

Answer: (A)

The airspeed defined as Vso refers specifically to the stall speed of an aircraft when it is in the landing configuration. This configuration typically includes settings such as flaps extended and landing gear down, which affect the aerodynamic properties of the aircraft. Vso is a crucial parameter for pilots as it indicates the lowest speed at which the aircraft can be controlled during landing. Understanding Vso helps ensure safety by alerting pilots to the stall threshold under landing conditions. The other options describe different speeds that are important in aviation but are not accurately characterized by Vso. For instance, the operating speed during departure is not focused on stall characteristics but rather on safe takeoff and climb performance, which is typically associated with a different airspeed designation. Vortex safety operating speed refers more to the operational limitations regarding wake turbulence rather than stall conditions. Lastly, the speed above stall during takeoff does not capture the essence of Vso, as Vso is specifically the stall speed in landing configuration rather than any speed exceeding stall.
