Current MNPS regulations:

Change to ICAO Doc 7030
“NAT Supp” Ch 4 (Amendment 9, April/2014)
From 1 January 2015 the means of compliance for demonstrating performance to 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” is coordinating changes
Task Force includes IATA, IBAC, IFALPA, ANSPs and State Regulators
Task Force to Report Progress at IMG/45 (November, 2014), then Implementation Plan to IMG/46 (May, 2015)
ICAO NAT Groups Discussing Policy on Area-Specific Authorization for NAT

4. Way Forward
The FAA will maintain an authorization for the NAT via OpSpec, MSpec or LOA, just as it does today
OSWG Industry is asked to appoint one or two representatives to address the forthcoming changes to the templates
(Related) The FAA will monitor and evaluate:
Possible (global?) changes to Communications and Surveillance requirements (PBCS)
Possible implementation of “High Level Airspace”
