How To Incorporate North Atlantic Tracks (and others) Into Your Flight Plan

Great tutorial @DiamondGaming4! Does SimBrief use the tracks or does it make it’s own?

Thank you!

I’m not sure. A great person to ask would be @Chris_S :)


@Cbro4 Shanwick assigns different tracks daily so I just grab the list every day to make sure. Random routing can also be used but of course you’ll be assigned a flight level either above or below the tracks.

Same thing for PACOTS.


This is so amazing thank you

Yes, Simbrief uses NATs. :)

Scroll down to the Route section!


After about an hour and a half of research, eyerolling, hair pulling and reading long monotone FAA regulations, I’m pleased to reveal how to find your “entry route”.

For the amount of research I put into it, I was pretty upset to find that it’s as simple as going to and making a few changes to the map. Without further ado, here’s how:

First, (as stated before) go to From there, go to Layers>Nav>North Atlantic Tracks, and check the boxes. The tracks should appear on the map for that given day. Each track should have one or two routes heading to it. It should look something like this:

Each of these branches towards a given track. If you zoom in close enough, you’ll find waypoints on the end of each route. For example, at the beginning of the routes heading to NATs “U” and “T”, the waypoint is “CEFOU.”

From CEFOU, the routes branch to either TUDEP or ALLRY, which are the entry waypoints for T and U. So, in your flight plan, all you do is put your domestic waypoints, then (assuming we’re taking U), put waypoints CEFOU and ALLRY, add the coordinates inbetween, and finish your flight plan with the exit waypoints and the other domestic routes on the other side of the Atlantic.

This will be put in the actual thread. I hope this helps some of you improve realism in your flights!


Correct me if I’m wrong but CEFOU stays the same, however U, and T will change everyday depending on weather?

They both change day to day. The entry route and track change based on what Gander and Shanwick decide.

After they waypoints are changed do they still use the same name?

Yes. The names are Zulu (southernmost), Yankee, X-Ray, Whiskey, Victor, Uniform, Tango, etc. The only thing that changes are waypoints.

For example, when I made this post the waypoints for Zulu were

TUDEP 52/50 53/40 53/30 53/20 MALOT GISTI

Today they are

43/50 46/40 48/30 49/20 BEDRA NERTU

The community is putting out some great tutorials today! Thank you so much, I’ll start using this from now on! Much more realistic :)


Thanks for the help. I greatly appreciate it.

Great tutorial I’m going to use it today. Just one question you know the rule of flying at even levels on westerly routes and odd levels on easterly routes does that not apply when using a track as it states above that on the Zulu track the flight levels are from 320 up to 400 using both even and odd levels so can you fly at any level?

I would recommend taking into account the IF flight levels. 99% of the time, you’ll find a matchup with the tracks. For example, today on track S (eastbound), the levels are 320 330 340 350 360 370 380 390 and 400. 330 and 370 are both cruising altitudes for eastbound, so you should use one of those. If the track you want to use does not have any matching levels, I would recommend using the Cruise Altitudes specified in this topic. Hope this helps!

Where do you get this information? Do you just search it up?

For those who love to add realism here are a few tips for flying the tracks.
(RNP 4nm, ADS and CPDLC).

MNPS airspace goes from FL290 to FL410.

Comms, monitor 121.5 and 123.45 at all times. HF SELCAL is used for voice comms and the squwak code for non radar covered airspace is 2000. CPDLC is used for ATC clearances.

If you have to avoid weather and have to deviate from the track centre line by more than 10nm then either climb or descend 500’.

It is normal to use SLOP offset procedures on the NATS tracks, that is to say offset RIGHT of track either 0,1 or 2nm to avoid overflying nearby aircraft at lower levels.

Vertical spacing is NOT in accordance with semi-circular rules instead it is 1000’ both ways.

(Edited to clarify, NATS tracks are either eastbound or westbound. If you look at the print out from the OP at the very top you will see the Eastbound levels, underneath you will see westbound levels NIL. These are the red-eye tracks for the early morning Europe inbound arrivals. You cannot fly the tracks eastbound if the timing dictates the tracks are westbound. Hence all levels are available in one direction in 1000ft steps. E.g. Westbound under semicirculars would be evens, 320,340,360 etc. However, on the tracks you can fly westbound at 330,350,370 etc. Once you exits MNPS airspace and enter regional airspace you will be asked to fly semi circulars by climbing or descending to an even FL. Hope that clarifies it.)

If you have an emergency on the NATS tracks you are to contain height loss until you have offset right of track by 15nm whilst maintain direction of flight. Once at R15, if you can maintain height then adjust your height by +/- 500’ to avoid flying out of the track at a standard track assigned FL, if necessary you can then depart the tracks north or south if a diversion is needed. If you cannot maintain height (engine failure or pressurisation) then descend to below FL290 in the direction of original flight before departing the track structure.

Real world rules. :D


Right here :)
