Definition
A time issued by Air Traffic Control telling a pilot when they can expect to receive an onward clearance — most commonly an Expect Further Clearance (EFC) time given when an aircraft is held at a fix or assigned a holding pattern. The pilot must be prepared to leave the holding fix at that time, and the EFC time also serves as the time at which the pilot will depart the holding fix in the event of two-way radio communications failure.
Plain English
A time ATC gives you so you know when to expect your next instruction. If you lose radio contact, you use that time to leave the hold and continue on your route.
Context Anchor
Common in instrument flying when a controller or published procedure tells a pilot what clearance may come next, especially for altitude, route, or approach changes.
Derivation
Expect comes from a Latin word meaning “to look out for” or “wait for.” Clearance comes from the idea of making a path clear or giving permission. Together, the phrase points to waiting for permission, not already having it.
Why Pilots Care
Treating an expect as an actual clearance can cause altitude or route deviations and loss of separation.
Grounding Statement
When you hear expect clearance, picture staying with your current instructions while getting ready for a possible next instruction.
Intuition Check
Do not hear expect clearance as “you are cleared.” It means plan for a later approval; only an actual clearance or direct instruction lets you act.
Example Sentence 1
Center instructed the pilot to hold east of the fix and gave an expect further clearance time of 1845.
Example Sentence 2
The pilot held the assigned altitude while waiting for the expected clearance to be issued.
