I am trying to build my route by the input of airways and fixes. Although i checked the airway and the fix are there in the FS9, I checked it by viewing the map and it was there and the airway is passing the fix. but the FMGS tells me its invalid entry!
but it can see another airway which routs the same.
From KEA(115.0) it cant read UR19 to VARIX
But it reads R19 to VARIX
-Is there any way to add or edit Airways in FS9 nav database?
