EMER FLAP action results in which configuration?

• A. Extends flaps to 0 degrees
• B. Slats retract fully
• C. Slats fully extend and flaps to move to 20 degrees
• D. Overrides the flap control lever only

Answer: (C)

EMER FLAP deployment is designed to maximize lift when normal systems may be unavailable. It uses the emergency hydraulic system to position the high‑lift devices to a preset, high‑lift state: the slats are fully extended and the flaps move to 20 degrees. This configuration increases wing camber and lift at low speed, helping with safe approach and landing under degraded conditions. The other ideas don’t provide the needed high‑lift configuration—0 degrees would not extend the surface, retracting the slats would reduce lift, and simply overriding the flap lever doesn’t specify the actual surfaces’ positions in emergency mode.
