What does EMER FLAP do?

What does EMER FLAP do?

• A. Extends flaps to 10 degrees
• B. Extends slats to 25 degrees and flaps to 30 degrees
• C. Disables the flap system
• D. Overrides the flap control lever and causes the slats to fully extend and flaps to move to 20 degrees

Answer: (D)

In emergency flap mode, the system takes control away from the pilots’ normal flap lever and uses a dedicated emergency pathway to guarantee high-lift deployment. This mode is designed to ensure you have enough lift at low speed even if the regular flap system has failed or is unresponsive. The result is a preset configuration that provides maximum lift without relying on normal controls. Specifically, EMER FLAP overrides the flap control lever and causes the leading-edge slats to extend fully and the trailing-edge flaps to move to a fixed position, typically around 20 degrees. This preset configuration is chosen to maximize lift for a safe approach and landing when quick, assured deployment is needed. Other options don’t match this behavior: some describe only partial or incorrect degrees for flaps or slats, or suggest disabling the flap system entirely. EMER FLAP is about forcing a reliable, high-lift state by overriding normal controls and moving to a defined slat-fully-extended and flap-20-degree configuration.
