Quoting Longhornmaniac (Reply 13): I can't vouch for the MD-11, but on the 747 and 737 the tracks are written as mentioned previously:
N45W60
S33W123 |
I use all three versions of the jet PMDG aircraft, PMDG B737NG & B744 in FS9 and B744 & Boeing MD11 in FSX...
Here is a NATrack that was in use on 25th October 2009-11-20

Now with PMDG’s the FMS (flight management system) uses a database with has is a copy of the real world database of all navigation points (VOR/NDB etc) and ‘waypoints’.
Over the Atlantic there are 100’s of waypoints, which are used for NATrack crossings – for example, you can see above after DOGAL (the start of NATrack C for Charlie) you have the navigation point 54/20 – now this in fact is entered into PMDG’s FMS system as 5420N. The next waypoint is 53/30 – which of course is entered as 5330N.
You can see the altitudes available below the NATrack route, in this case FL320 thru FL400 west bound and no altitudes available travelling east bound (this is entered to remind pilots they can’t use this NATrack to fly east bound.
It’s extremely important to use the most up to date NATrack information when flying on line (Vatsim etc) – if you don’t you will get told off my other on line pilots and if ATC is on line or comes on line they will soon kick you off line if you have not entered an active NATrack on your flight plan and you’re not flying it to the letter (or degree)...
I must admit I still plan my flights via ‘FSNavigator’ which I update every month along with all my aircraft FMS with data from Navigraph (http://www.navigraph.com/www/default.asp). Using Navigraph means PMDG’s
SID/STAR information is also upgraded/updated... Navigraph also have an amazing system called ‘Navigraph nDAC 3’ – a programme which allows you to download and upgrade
SID/STAR charts and includes ‘en-route charts’ (those highways in the skies, along with their waypoints/navigational aids and official names). Many people don’t both using the system on FS9 and FSX, which is a real shame as real world airlines do!
