EFC stands for which term?

• A. Electronic Flight Console
• B. Engine Fuel Control
• C. Expect-Further-Clearance
• D. External Flight Communications

Answer: (C)

Expect Further Clearance is used in ATC communications to tell you that you should await the next instruction from ATC rather than taking any further action on your own. It comes into play when you’re holding, taxiing, or approaching a point where you’ll need additional clearance to continue your route. The pilot should maintain the current clearance, altitude, and position until ATC issues the next clearance. This term sets the expectation that another instruction will follow, rather than granting immediate permission to proceed along the full flight plan.

The other terms refer to things outside this ATC instruction: one is a cockpit display/console component, another is an engine subsystem, and the last is not a standard aviation term for communications.
