NAT Expanded data link mandate

It’s time for everyone’s favourite topic – DATA LINK MANDATE! New things are happening on December 7th. Don’t worry, we’ll help.

Right Now, if you’re using the NAT tracks, between FL350-390, you’re mandated to use data link services. Simply put, you must be equipped with CPDLC and ADS-C (FANS 1/A ready and able).

On December 7th 2017, the data link mandate will expand to the entire ICAO NAT Region between FL350-390, with a few exceptions. We’ve got the image below showing you the area. White routes are exempt, as well as the grey border areas (we like the Big Fish).

-Everything north of 80°North
-New York Oceanic East FIR (was previously all of NY Oceanic)
-Routes T9, T213, T13, T16, T25. (see: The Tango Routes)
-The Blue Spruce Routes (white lines)
-Areas that currently have radar, multilateration (is this a word?) and/or ADS-B. (the grey areas)
Note: If any of the NAT Tracks go into the grey areas, you won’t be exempt while on the tracks.

Be ready, January 30th, 2020, all of the NAT ICAO Region will have the Data Link Mandate, above FL290, including the Tango Routes as well as those little grey areas.

To figure out where you are welcome on the NAT, depending on what equipment and training you have, check out our quick and dirty guide here.
