Does anybody know how to put in coordinates that are very specific? I know how to do simple coordinates for flight across the Atlantic or Pacific that are something like 5540N. Those are easy. But on my currently flight I have the following waypoints 60N120W 55N122W 50N123W You'll notice they are specific 122W and 123W, how are those entered? I've tried just about every format I can think of and still no cigar. I used 60N12, 55N12 and those were close but wrong and took me off course. Anybody know how to enter the more specific coordinates like this?

Try 60N20, 55N22 and 50N23.  They should work (you drop the hundred digit, not the unit digit, for the longitude).

60N12 is N60 W112, which is why you were close but wrong.

Apart from the five character codes, there are two other ways of doing this (though whether they work with the 777 I don't know).

For an exact position down to a tenth of a minute use:

Nddmm.m/Edddmm.m
Sdd.mm.m/Wdddmm.m

So in your example

N5500.0/W12200.0

Or for whole degrees only:

NddWddd
SddEddd

So for your waypoint this should work:

N55W122

In both cases the degrees for E and W must have three digits, so add a leading zero for anything less than 100.
