If the EMER FLAP switch is set to DEPLOY above the flap limit airspeed of 230 kts, what happens to the flaps/slats?

• A. They deploy normally
• B. They will not deploy
• C. They deploy partially
• D. They retract

Answer: (B)

The system protects you by enforcing a flap limit airspeed. When the EMER FLAP switch is set to DEPLOY, the flaps/slats are allowed to extend only up to the defined limit speed. If you’re above 230 knots, the control logic prevents deployment to avoid excessive aerodynamic loads or potential damage. So at speeds above the limit, they won’t move—they stay in their current position. To use emergency flaps, you must slow to at or below the limit, then DEPLOY will extend them as needed.
