Hello. I’ve been using Charts for many years now. Setting a polar route from PANC (Anchorage) to EGLL (London) I asked Charts to ‘Generate’ a route, which it did. But, the waypoint names would not be accepted by the PMDG 777-200 LR FMC saying ‘Not in Database’. These are the generated points… 74N32..77N18..8094N..8065N..7841N..7426N..7017N..6511N. Not sure how to correct these. Also, when I manually tried to find waypoints for this route, they seemed very sparse. Is that normal for this high altitude zone ?
Many thanks. Your products are brilliant and much appreciated. Bob Reardon
These are shorthand forms for latitude/longitude coordinates. Some of them exist as waypoints in the database, others not.
As you’ve discovered, 8066N and 8064N are in the database but not 8065N – indeed.
That doesn’t make 8065N “invalid” per se, although typically then you would use a non-abbreviated form like 80N065W or N80W065 as I explained earlier. Probably Navigraph Charts should do the same in this case.
If you use Navigraph Chart’s “Export” function, select “PMDG Flightplan”, save the file somewhere and open it in a plain text editor (e.g. Notepad), you will notice Charts automatically converts 8065N to the non-abbreviated form N80W065 in its export.
You could use the exported file as a reference to manually enter your route in the FMS, or you can actually use this file as a “company route” in the PMDG if you save it to the correct folder.
Unfortunately I am not sure exactly what the correct path is as I prefer to import directly from Simbrief, but in theory it should be somewhere like described in the following avsim forum post:
