What is Vso in aviation terms?

Vso is a crucial term in aviation that refers to the stall speed in a specified configuration, typically when the aircraft is in landing configuration, which includes full flaps and gear down. This stall speed is often expressed in knots and is essential for pilots to understand because it indicates the minimum speed at which the aircraft can safely fly without stalling. Knowing Vso helps pilots manage their airspeed during critical phases of flight, particularly during approach and landing.

The value of 49 knots represents the stall speed for specific aircraft models when configured for landing. This speed will vary based on the aircraft's design and weight, making it unique to each aircraft. Therefore, recognizing Vso as a specific value and understanding its significance in safe flight operations is essential for successful piloting.
