I've finally figured out how to fly the Concorde in FS9, and am now totally obsessed with it! I use the SSTSIM version which I bought from Flight1 after flying the ProjetMach2 version, which is free. Anyway I was wondering if anyone can aid me in figuring out the best way to flight plan with the INS, since it requires Lat Long for all its coordinates. There are some files on avsim of some concorde INS flight plans, and SSTSIM comes with actual photocopies of the Air France and Speedbird flightplans, including some charter missions. But I'm looking for some help in creating my own runs.
