  2. NAT MNPS to PBN Transition Current MNPS regulations: • Contained in 14CFR Part 91Includes “standard deviation… less than 6.3 NM (11.7 km)” criteria Change to ICAO Doc 7030 • “NAT Supp” Ch 4 (Amendment 9, April/2014) 4.1.1.5.1.5 From 1 January 2015 the means of compliance for demonstrating performance to 4.1.1.5.1.2 a) above shall be in accordance with the RNAV 10 or RNP 4 navigation specifications as detailed in the Performance-based Navigation (PBN) Manual (Doc 9613).

  3. NAT NMPS to PBN Task Force • The NAT’s “MNPS to PBN Task Force” changes NAT IMG Decision 45/2 –  Re-naming of the NAT MNPSA • That the ICAO Regional Director, Europe and North Atlantic, advise States and international organizations that the airspace currently designated as the North Atlantic Minimum Navigation Performance Specifications Airspace (NAT MNPSA) be re-named as the North Atlantic High Level Airspace (NAT HLA) as of 4 February 2016.

  4. Way Forward • The FAA will maintain an authorization for the NAT via OpSpec, MSpec or LOA, just as it does today • OSWG Industry to work with FAA on language • (Related) The FAA will monitor and evaluate: • Possible (global?) changes to Communications and Surveillance requirements (PBCS) (June PBCS Conference) • Progress of the NAT Reduced Lateral Separation Minima (RLat SM) Trial, set to begin in November/ 2015
