# How are NATs connected to European Airways?

The North Atlantic Tracks connect Northern Europe to North America. To enter/exit NATs over North America, the North American Routes (NARs) are used.

Questions: What about the European side? What are the rules to enter/exit NATs? What airways must be flown? Can I find the official information written anywhere?

Note: Ideally I would like to find a list of routes (directs?) that suggests the pair of waypoints linking the generic NAT and the european airways system. In the past North Atlantic European Routing Scheme (NERS) was used but nowadays it appears they have been dismissed.

• @mins the question is not duplicate since my question asks for information about the part of airspace connecting the NATs and the european airwways. I am not asking for NATs information where to download it. – Federico Gentile Jan 18 '17 at 9:37

There is no equivalent in Europe to the North Atlantic Routes, you simply file direct from point to point. This is the routing for a flight on Wednesday 18th of January, 2017 (DAL4).

MERIT HFD PUT WITCH ALLEX N263A JOOPY NATS RESNO NATS NETKI NIBOG REMSI UL603 SOGPO UT149 OTSOP T149 LIPMI T150 ROLIS

You see that the route terminates NAT S at NETKI NIBOG REMSI which are directs, until the flight joins the upper airway UL603 at REMSI.

Here is the routing in SkyVector.

And here is the screenshot from the FlightAware flight.

• For some reason SkyVector doesnt like NIBOG. – SentryRaven Jan 18 '17 at 9:38
• Thanks for the answer. Flying directs is something I was expecting. However I believe there must be a list of directs that suggests the pair of waypoints linking the generic NAT and the european airways system no? – Federico Gentile Jan 18 '17 at 9:40
• The flights on the European side are validated through CFMU for routing and slot management, but essentially, you will not have a list but just need to pass the route through CFMU. If CFMU doesnt object due to restrictions, then you are free to file it. AFAIK. – SentryRaven Jan 18 '17 at 9:42
• What is CFMU and AFAIK? I also suppose that only certain waypoints from the european side may be selected for directs to NATs. Otherwise any waypoint would be acceptable no? – Federico Gentile Jan 18 '17 at 9:43
• CFMU and AFAIK --> As Far As I Know – SentryRaven Jan 18 '17 at 9:44
