" . . . like usuall microsoft incorrectly made KIGX"Huh? With approximately 22,000 airports IMO Williams, Chapel Hills, SC got a pretty fair shake from FS9.
I don't mean to sound insulting but I've never heard of Horace Williams Airport, Chapel Hill, North Carolina, USA.
I went there in FS9 and compared it to Google Earth. Most of KIGX parking bays are laid down with apron cover, all the taxiways are there and the runway has strart locations.
That sounds pretty comphensive to me All that's left for AI traffic is to add some parking places (of the requisite size) and the flighplans. This can be completed using AFCAD2 and TTools.
Hangars can be added using Rwy12 All these programs are FREE and come with complete instructions.
Good Luck and have fun . . .
