Hi. Does anyone know if there is a document (similar perhaps to 'AircraftContainerSDKFS2004.doc' for the aircraft.cfg file) that explains all the elements of an FS9 .flt file? I assume there isn't such a thing or I'd have probably come across it by now??On occasions I want to make manual alterations or additions to an existing flight plan. This is usually OK, but can anyone tell me what the values in the lines WpInfo0,WpInfo1,WpInfo2 etc. are (in the section "GPS-Engine")? The penultimate value in each line (a two or three-figure number and a decimal place) represents what exactly for example?Many thanks!Martin

That info you provide looks like it comes from a .flt file, which is a saved flight.That is not a flight plan file, those have .pln extensions.To answer your question, I don't know of any file such as you describe.If you want to manually edit flight plans you would edit the .pln file , not the .flt file.I suspect those entries in the .flt file are FS's way of knowing where you are in a saved flight in relation to that saved flight's flight plan.regards,Joe

Yes, I should have written 'saved flight file', not 'flight plan', you are right. It's the flt plan that I want to edit from time to time (to save having to load up FS9 and the flight itself and save small changes that way) - the pln file is simple and quite short of course.M.
