ARFF Radio Call Signs

AIM ¶ 6-5-2 — ARFF Radio Call Signs

AIM 6-5-2: Learn the preferred ARFF Incident Commander radio call sign format used with flight crews and ATCT during airport emergencies.

In Plain English

AIM 6-5-2 establishes the preferred radio call sign for the Aircraft Rescue and Fire Fighting (ARFF) Incident Commander (IC) when talking with the flight crew and the FAA Air Traffic Control Tower (ATCT) during an airport emergency.

The standard format is:

"(Location/Facility) Command"

Examples given in the AIM:

LAX Command
Washington Command

Why this matters operationally:

It gives flight crews and controllers an instantly recognizable identifier for the on-scene fire/rescue boss during a high-stress event.
It separates ARFF coordination traffic from normal ATC call signs, reducing confusion on shared frequencies.
As a pilot, knowing this convention helps you quickly understand who is directing ground rescue efforts and to whom you should pass critical information (souls on board, fuel remaining, hazards, evacuation status).

Note that the AIM is informational guidance, not a regulation — but this call sign convention is the recommended standard across U.S. airports.
