2016 NAT Document #007

New Year, New Documentation

A new version of the North Atlantic Operations & Airspace Manual, NAT Document #007 has been released by the NAT Systems Planning Group. Here's a link to download a PDF copy, NAT#007, 2016

New Type of NAT Airspace Label

On 04 February 2016, the that airspace formerly known as the “North Atlantic Minimum Navigational Specifications Airspace”, MNPSA will add the BODO Oceanic FIR and will now designated as the “North Atlantic High Level Airspace” NAT HLA (FL285-420 inclusive). This re-designation excludes the BOTA and SOTA areas of the Shanwick OCA.

Check Your MNPS Approval for NAT HLA Acceptance

For MNPS approvals issued before January 2013, the State of Registry will have to verify that the lateral navigation capability of approved aircraft MNPS Approvals based on the “6.3 NM” non-PBN standard. I'm not sure what this means in terms of LOA and OpSpec reviews yet.

For MNPS approvals issued between JAN 2013 and JAN 2015, approvals MAY have been based PBN specifications, RNP-10 or RNP-4. The State of registry will need to verify an operator’s lateral navigation capability to PBN specifications, RNP-10 or RNP-4.

For Approvals issued after January 2015 the navigation system accuracy requirements for NAT MNPSA/HLA operation should only have be based on the PBN specifications, RNP-10 or RNP-4

MNPS Approvals based on the “6.3 NM” non-PBN standard will no longer be accepted beyond January 2020.

Interesting to Note

The NAT SPG stayed with the position ETA description of “3 Minutes or more”. I think they should of used “Greater than 2 Minutes” for clarity sake and commonality with FAA/ICAO definitions.


  • 1. If your MNPS approval is based on INS only, you may have a problem
  • 2. After 2020 all NAT HLA approvals will need to be RNP(RNVAV)-10 or better
  • 3. “3 Minutes or more” still means the same as “Greater than 2 Minutes”
  • 4. Mach Number Technique  means “+/- zero” speed assignment in the NAT
  • 5. The NAT remains the busiest and most regulated airspace… to remain “Safe”
