  • 2-3-8. AIRCRAFT EQUIPMENT SUFFIX

    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.

      NOTE: Directly changing the equipment suffix with a symbol preceded by a slant instead of amending the aircraft equipment codes may unintentionally alter or delete other equipment codes.

    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.
      • EXAMPLE
      • “Cessna Three-ten slant Tango.”
      • “A-Ten slant November.”
      • “F-Sixteen slant Papa.”
      • “Seven-sixty-seven slant Golf.”

      /H and /O are intended for ATC use only. These suffixes are not published in the Aeronautical Information Manual.
