reference speed


reference speed
The target speed by airline pilots on short finals. This is referred to as VREF + 5, VREF + 10, or VREF + 15 on various stages of the approach. VREF is factored on the stalling speed (1.3 × VSO ) and so varies with aircraft weight. VSO stands for stalling speed with the undercarriage and the flaps down.
