Equipment codes

An equipment code describes the transponder and/or navigation capability of aircraft. The equipment code is usually designated as a one-character suffix to the aircraft type in block 3 of the FAA flight plan form. Air traffic controllers (ATC) issue clearances based on filed suffixes, therefore it is important for pilots to use the appropriate suffix. For example, if a desired route requires GPS, then the pilot should file /G, even if the aircraft also qualifies for other suffixes. Pilots are recommended to file the maximum capability of their aircraft in the equipment suffix.
