The North Atlantic Systems Planning Group, NAT SPG has published the newest version of NAT Document #007, North Atlantic Operations And Airspace Manual. This is the “How-To” book for operating in and around the NAT HLA. Here is a link to the download.
There are not many large procedural or philosophical differences from the previous edition issued in July of 2019. The incorporating of the NAT Data Link Mandate is the standout for differences from the previous edition. This seems to touch just about every chapter in this new document. You will find better-defined references and updated sources of Oceanic/Remote along with CNS information for all operators. Of course, there are editorial changes across this new document.
Please keep in mind, this is not a stand-alone single source document. This must be understood with ICAO Annex 2 and 6, Document #4444, #7030 and your individual LOA/OpsSpecs, AFM, QRH and company IOM. There is a helpful list of additional reference material in Attachment #11, FAA’s AC 91-70B and the North Atlantic Regional Resource Guides.
