Guidance concerning Air Navigation in and above the NAT MNPSA CHAPTER 4Flights Planning on Random Route Segments in a Generally Eastbound or Westbound Direction at/or Southof 70°N4.2.6 The requested Mach Number and flight level should be specified at either the last domesticreporting point prior to oceanic airspace entry or the OCA boundary.4.2.7 The route of flight should be specified in terms of the following significant points, withestimates included in Item 18 of the flight plan:a) the last domestic reporting point prior to the oceanic entry point;b) the OCA boundary entry point (only required by the Gander, Shanwick, New York andSanta Maria OACs);c) significant points formed by the intersection of half or whole degrees of latitude, withmeridians spaced at intervals of ten degrees of longitude from the Zero degree E/W(Greenwich) Meridian to longitude 70°W;d) the OCA boundary exit point (only required by the Gander, Shanwick, New York and SantaMaria OACs); ande) the first domestic reporting point after ocean exit.4.2.8 Each point at which a change of Mach Number or flight level is requested must be specifiedand followed in each case by the next significant point.Flights Planning on a Generally Eastbound or Westbound Direction on Random Route Segments North of70°N4.2.9 Flight planning requirements for flights in this category are identical to those listed forflights on random route segments at/or south of 70°N except that a route should be specified in terms ofsignificant points formed by the intersection of parallels of latitude expressed in degrees and minutes withmeridians normally spaced at intervals of 20° from the Zero degree E/W (Greenwich ) Meridian to longitude60°W, using the longitudes 000W, 020W, 040W and 060W.Flights Planning on Random Routes in a Generally Northbound or Southbound DirectionNote : The ICAO Regional Supplementary Procedures for the NAT Region (Doc.7030) state thatflights operating between North America and Europe shall generally be considered as operating ina predominantly east-west direction. However, flights planned between these two continents via theNorth Pole shall be considered as operating in a predominantly north-south direction.4.2.10 Flight planning requirements for flights in this category are identical to those listed forflights operating on random route segments at/or south of 70°N except that the route should be specified interms of significant points formed by the intersection of whole degrees of longitude with specified parallelsof latitude which are spaced at 5° intervals from 20°N to 90°N.Flights Planning to Enter or Leave the NAT Region via the European or North American Regions4.2.11 To provide for the safe and efficient management of flights to/from the NAT Region,transition route systems/schemes are established in the NAM and EUR Regions (NARs and NERs,respectively). These schemes detail particular domestic routings associated with each oceanic entry orlandfall point. Flights in this category must be planned in accordance with these schemes and, in particular,OTS flights should comply with the daily published NAR/NER restrictions as specified in the relevant OTSmessage. Canadian Domestic route schemes and the US East Coast Link Routes are also published. FlightsNAT Doc 007 23 Edition 2010
