FSX – Flight Plan Creator v12.4, using Excel. This Excel workbook will assist in making flight plans for FSX using the program AIFPC.EXE. This is a de-compile/compile program for the TrafficAircraft.bgl file. The Excel spreadsheet has gone thru a number of changes, to make the creation of AI traffic for a particular airport/airports quick and easy. This version corrects the ETD time calculations. Also added some error catching fomulas to the repeat times. By Gary McDonald.
