What is the stall speed in the landing configuration (Vs)?

The stall speed in the landing configuration, commonly referred to as Vs, represents the minimum airspeed at which an aircraft can maintain controlled flight without stalling in that specific configuration. In the case of many aircraft, the landing configuration typically includes deployment of flaps and possibly other modifications to the aircraft's aerodynamic shape. This configuration lowers the stall speed, allowing for safer landings at lower speeds.

For the aircraft in question, 91 knots is specified as the stall speed in the landing configuration. This figure is crucial for pilots to know, as it influences approach and landing strategies. Ensuring that the aircraft is above this speed during critical phases of flight helps maintain adequate control and prevents loss of lift that can occur when the aircraft operates below this speed. Knowing the correct stall speed allows pilots to make informed decisions during approach, ensuring safety and compliance with operational standards.
