Flaps/slats maximum extended speed is described as Vfe next-10kt. Which option matches this value?

Flaps/slats maximum extended speed is described as Vfe next-10kt. Which option matches this value?

• A. Vfe next-10kt
• B. Vmo
• C. Vne
• D. Vref

Answer: (A)

The key idea is the speed limit for configurations with high-lift devices (flaps/slats) extended. Vfe is the maximum speed with those devices out. The notation “Vfe next-10kt” means you add a 10-knot buffer to that limit, giving the true maximum permissible speed when flaps/slats are extended. This limit is lower than the aircraft’s clean-air speeds like Vmo or Vne and is not related to Vref, which is an approach reference speed. So the value described as Vfe next-10kt is the correct match.
