This section provides guidance on information required by FAA for automatic assignment of RNAV Standard Instrument Departures (SID), RNAV Standard Terminal Arrival Routes (STAR) and/or RNAV Point-to-Point (PTP).  There are currently two (2) types of RNAV capability used in the domestic U.S:

• RNAV 1 and/or RNAV 2 capability per Advisory Circular (AC) 90-100A, U.S. Terminal and En Route Area Navigation (RNAV) Operations, is required for assignment of RNAV SIDs and STARs (RNAV 1) and en route RNAV 2.
• Point to Point (PTP) capability per AC 90-45A, Approval of Area Navigation Systems for Use in the U.S. National Airspace System, is required for assignment of RNAV PTP routes.

Users must file in accordance with (IAW) FAA Form 7233-4 for automatic assignment of RNAV SIDs, STARs and/or PTP in U.S. domestic airspace and include additional information per the below guidance:

If you are RNAV 1 and/or RNAV 2 capable

• Item 10, Equipment – In addition to identifying all available and serviceable communication, navigation, approach aid and surveillance equipment carried on your aircraft, insert the character “Z”.
• Item 18, Other Information – Insert “NAV/RNV” followed by the appropriate RNAV accuracy value(s) per the following:

• To be assigned an RNAV 1 SID, insert the characters “D1”.
• To be assigned an RNAV 1 STAR, insert the characters “A1”.
• To be assigned en route extensions and/or RNAV PTP, insert the characters “E2”.
• To prevent assignment of an RNAV route or procedure, insert a numeric value of “0” for the segment of the flight. Alternatively, you may simply remove the segment of the flight indicator and numeric value from the character string.

Examples: NAV/RNVD1 or NAV/RNVD1E0A0 (Same meaning)
NAV/RNVA1 or NAV/RNVD0E0A1 (Same meaning)                                    
NAV/RNVE2 or NAV/RNVD0E2A0 (Same meaning)
NAV/RNVD1A1 or NAV/RNVD1E0A1 (Same meaning)
NAV/RNVD1E2A1

If you are RNAV PTP capable but not RNAV 1 and/or RNAV 2 capable

• Item 10, Equipment – In addition to identifying all available and serviceable communication, navigation, approach aid and surveillance equipment carried on your aircraft, insert the character “Z”.
• Item 18, Other Information – Insert “RMK/PTP” and “NAV/RNVE99”

Example:  RMK/PTP NAV/RNVE99

Special Notes:

• The following variations will be accepted in ERAS for automatic assignment of RNAV routes:
• One or more spaces may follow "NAV/".

Example:  NAV/  RNVD1A1

• The “D”, “E” and “A” characters may appear in any order following “NAV/RNV”

Examples:  NAV/RNVD1A1E2
NAV/RNVA1D1E2

• Additional items required by other automation systems may be filed after NAV/, in any order:

Examples:  NAV/RNP10 RNVD1E2A1
NAV/RNVD1E2A1 RNP4
NAV/RNAV1 RNAV5 RNVD1E2A1

• If the Item 18 entries following “NAV/” do not follow the above instructions, the flight plan will be accepted by ERAS but you will not be automatically assigned RNAV.  Common errors include:
• Putting spaces between RNV, D1, A1 and/or E2 – no spaces are allowed between the segments.
• Filing “RNAV” instead of “RNV” – RNAV is not acceptable in the U.S. domestic string after “NAV/”
