Which symbol represents the minimum steady-flight speed or stalling speed in the landing configuration?

The symbol representing the minimum steady-flight speed or stalling speed in the landing configuration is Vso. This speed is defined as the stall speed in the landing configuration, which includes flaps and landing gear being extended. It is crucial for pilots and dispatchers to know this speed as it indicates the slowest speed at which the aircraft can safely be flown, ensuring smooth control and avoiding an aerodynamic stall while landing.

Understanding Vso is important, as it dictates the lower limit of the airspeed range for safe landing operations. Pilots must maintain airspeed above this value to ensure adequate control and performance during approach and landing phases. The other symbols, being related to different flight scenarios or configurations, do not specifically represent the stall speed with flaps extended in the landing configuration as Vso does.

In summary, Vso specifically addresses the critical aspect of stalling speed during landing, giving it its unique significance in flight operations.
