What is Vref and how is it typically related to stall speed?

Vref is the reference landing speed you aim for during the final approach and landing. It’s tied to the stall speed in the landing configuration, with a typical target of about 1.3 times Vs (the stall speed with landing configuration). This margin above stall helps ensure you remain controllable in the approach, even with gusts, configuration changes, or needing to maneuver to land. As the airplane’s weight increases, stall speed goes up, so Vref increases accordingly to maintain that same safety buffer. In practice, pilots may add a gust factor to Vref to account for wind. This speed is not related to climb performance or maximum cruising speeds.
