Multiple Choice

Vapp is chosen to maintain stabilized approach with margins relative to Vref. Which statement is true?

The speed used on final approach is set with a safety margin above the reference stall speed to ensure a stable, energy-appropriate descent. Vref provides the reference for stall margins in the landing configuration, and Vapp is the actual approach speed chosen to keep the approach stabilized while maintaining adequate margins above Vref. This margin accounts for gusts, configuration changes, weight, altitude, and pilot inputs, so the speed isn’t simply equal to Vref or a fixed multiplier. That’s why the best statement is that Vapp is chosen to maintain a stabilized approach with appropriate margins relative to Vref.
