What?! More codes? Yep, that is correct. New codes can be used when filing your flight plan to indicate advanced Nav capabilities that can\u2019t be described without them.<\/p>\n

\n

What are the new codes?<\/h2>\n

As published in the FAA AIM, Appendix 4, Table 4-4.<\/p>\n\n\n\n\n\n\n\n\n\n\n

RNP 2 Oceanic\/Remote<\/td>\nM2<\/td>\nFlight is authorized for RNP 2 oceanic\/remote operations.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
\n

Where do the new codes apply?<\/h2>\n

At this point, the new codes only apply to the FAA (United States). This is because no other Air Navigation Service Provider (ANSP) has documented\/released their plans to the public as the FAA has. Work is ongoing in the ICAO ATMRPP to publish the scheme and agreed codes which are coordinated between ICAO panels and various working papers.<\/p>\n

\n

What codes can I put into my aircraft\u2019s profile?<\/h2>\n

As the location for these codes is Item 18 NAV\/ field, and the NAV\/ field is just a free text field, you can put these codes in your profile today. However, keep in mind that, as of right now, there is no ANSP that is utilizing these codes.<\/p>\n

As of 06-FEB-2023, the FAA has advised they plan to implement the Z1 code into their systems sometime after 30-MAR-2023. Additionally, the FAA states\u00a0Operators planning to use the STAYY SID in ZLA to have their flight plan entries ready by March 2023.<\/em><\/p>\n

\n

Should I still be using \u201cRNVD1E2A1\u201d in my flight plan?<\/h2>\n

No. The FAA AIM and AIP have removed this information from their publications. The FAA systems will still accept and process the RNVD1E2A1 coding, but remember that doing this will override your PBN codes. This means if you have RNP1 PBN codes (O1\/O2\/O3\/O4) in your profile, the FAA will downgrade you to just RNAV1 capabilities and no RNP1 capabilities because the RNVD1E2A1 only describes RNAV capabilities. So for RNAV2 (Q, T, and Y routes), RNAV1 (RNAV SIDs and STARs), and RNP1 (RNP SIDs and STARs), it is sufficient to include the corresponding codes in PBN\/.<\/p>\n

\n

If I already have RNP2 in Item 18 NAV\/ of my current profile, do I need to replace it with M1 and\/or M2?<\/h2>\n

There are currently no known operations that require the M1 and M2 codes. If your profile currently includes \u201cRNP2\u201d in Item 18 NAV\/ field, then leave \u201cRNP2\u201d in there, but if you do have the necessary capability\/approval (see Flight Plan Codes vs. Required Operational Authorizations<\/a>), then you can include M1 and\/or M2 in the NAV\/ field as well. A few ANSPs require RNP2 to operate on certain airways\/airspace and have yet to officially change over to using the new M1\/M2 codes. Continue to use \u201cRNP2\u201d until published requirements change in these countries:<\/p>\n
