Has anyone tried to calibrate a custom map in Flight Monitor? In particular a map West of London. The program rejects the longitudes if the more Westerly point is greater than the more Easterly point. I'm in the neighborhood of -118 degrees and the Westerly point is and should be greater in terms of absolute numbers. The program doesn't use negative numbers but uses an S for South of the Equator and I assume a W for West of the Prime Meridian. Here are my inputs:
118 54 47.848 W
118 54 17.564 W
I can see how someone could argue which number is greater but in any case, I can't calibrate it.
