Aircraft Equipment Suffix

JO 7110.65BB, Change 3, effective July 9, 2026 · Official text on faa.gov

  1. The aircraft equipment suffix identifying communication, navigation and surveillance (CNS) capability is generated by automation using the equipment codes of the ICAO flight plan. To change a suffix, the CNS equipment codes must be modified, allowing automation to translate them into the proper suffix. If using unsupported automation platforms (OFDPS and FDP2000), verbally coordinate changes with adjacent supported facilities.
  2. ERAM and ATOP are best suited for making changes to the equipment codes in an ICAO flight plan. For FDIO entries, if uncertain of the proper format to correctly amend an equipment code, verbally coordinate the change with the appropriate en route facility.
  3. For VFR operations, indicate the aircraft's transponder and navigation capabilities by adding the appropriate symbol, preceded by a slant (See TBL 2-3-10).
  4. GNSS-equipped aircraft:
    1. Have an equipment suffix of /G, /L, /S, or /V.
    2. May be determined by executing an ICAO flight plan readout and verifying a filed “G” in the ICAO equipment list.
    3. May be determined by verifying with the pilot that the aircraft is GNSS-equipped.
  5. When forwarding this information, state the aircraft type followed by the word “slant” and the appropriate phonetic letter equivalent of the suffix.
