Definition
A NOTAM contraction used in coded notices to indicate matters relating to staff communications — that is, communications systems or services used by aviation personnel on the ground rather than by aircraft in flight.
Plain English
A short code (CCCC) that appears in NOTAMs to flag that the notice is about communication systems used by ground staff at an airport or facility.
Context Anchor
Seen in FAA abbreviation lists and may appear in NOTAM-related material.
Why Pilots Care
NOTAMs are written in heavily abbreviated code. Recognizing CCCC lets a pilot quickly tell that the notice concerns ground staff communications rather than something that directly affects flight, so they can judge its relevance to the planned operation.
Intuition Check
Do not read CCCC as a radio frequency or a pilot communication procedure. In this context, it is simply shorthand for staff communications.
Example Sentence 1
While reading the day's NOTAMs, the pilot saw CCCC in a notice and recognized it as referring to staff communications at the airport.
Example Sentence 2
Pilots checked the CCCC board before departure to see any staff notes on runway conditions.
