Flight Plans for Syracuse in FS2004

Other than flying the planes, arguably the most fun thing to do with Microsoft Flight Simulator is to build up the AI traffic files, which use the same simulated aircraft (usually) as what the player can fly. This is a lot like setting up a model trainset, only with planes. The format of the files is really simple, as you can see here, although each traffic .bgl file is made by compiling three text files, for the selected aircraft and airports, and for the flight plans themselves. The most popular compiler is called TTools, and I have it pictured next.
