EGGX Shanwick FIR 2017 Operational Changes – Oceanic

Because Shanwick is the only true Oceanic FIR in the NAT region, we’ll use this page for NAT changes, including CZQX/Gander, BIRD/Iceland, ENOB/Bodo, LPPO/Santa Maria, and KZNY/New York East.

Feb 15th, 2017 In the first six weeks of 2017 there have been some important changes on the NAT/North Atlantic. These are published in the latest edition of NAT Doc 007, January 2017.

  • TCAS 7.1: From January 1st, 2017, TCAS 7.1 is required throughout the entire NAT region.
  • Cruising Level: Effective 2017, you no longer need to file an ICAO standard cruising level in NAT airspace.
  • Gross Nav Error:  is now defined as greater than 10nm (used to be 25nm)
  • Contingency Procedure: Published January 2017, a new turn-back (180) procedure is introduced – turn back to parallel previous track by 15nm.
  • Datalink Mandate Exemptions: Announced January 2017, new exemptions for Phase 2B of the Datalink mandate, which will start on December 7, 2017 (FL350-390). Exempt: Tango Routes, airspace north of 80N, and New York OCA.

Feb 15th, 2017: FSB published the full NAT Crossing Guide “My first North Atlantic Flight is tomorrow“.

  1. I cannot find a source reference for the “Contingency Procedure: Published January 2017, a new turn-back (180) procedure is introduced – turn back to parallel previous track by 15nm.” Are you able to provide a link? Thx

  2. Hi David, yep, the source is the new NAT Doc 007 –

    Page 17: “Modifications to the Contingency Procedures, to take account of possible turn-backs when operating in RLatSM airspace, are included in Chapter 13.”

    13.3.5 Before commencing any diversion across the flow of adjacent traffic or before initiating any turn-back (180°), aircraft should, while subsequently maintaining a same direction 15 NM offset track , expedite climb above or descent below the vast majority of NAT traffic (i.e. to a level above FL410 or below FL280), and then maintain a flight level which differs from those normally used: by 1000 ft if above FL410, or by 500 ft if below FL410. However, if the pilot is unable or unwilling to carry out a major climb or descent, then any diversion or turn-back manoeuvre should be carried out at a level 500 ft different from those in use within the NAT HLA, until a new ATC clearance is obtained.

  3. Do you have a link to the V.2017? All I can find is V.2016-1. Thanks!

  4. I have a question related to what Dave H brought up. I found the same section (13.3.5) that FSB included in their reply to Dave H. I understand that it is relevant to RLatSM because it recommends an offset of only 15nm, but it is not specific to a turn-back as it specifies “…while subsequently maintaining a same direction 15 NM offset track…”. So if I am reading it correctly, it is suggesting that you continue in the same direction, but offset 15nm, and then descend/climb as appropriate before making any turn across the OTS or making a turn-back. Am I understanding this correctly?
