hello
I have downloaded all usa flight numbers from the airnav server from USA1 to USA9999 (no alpha numeric flights if there is any) but removed the flights without routes (leaving 1016), Changed the USA to AWE and saved them to CSV which you can import into into your navdata.db3 using a sql editor. the format is
Flight, Origin, Via , Destination
I obviously cant be held accountable for the accuracy of the data since it is just airnav's usa routes converted to the correct awe.
