Unfortunately, some of the Navaid's as mentioned within the AIP's are either missing from FS9 or are there but with incorrect frequencies etc...
cue me, flying along wondering why I cannot get a signal... until i notice the frequency is different in the FS9 World Map
Is it actually possible to create missing navaid's and/or edit existing ones to use the correct idents/frequencies/names etc????
