I've added a new property, /controls/parking-brake (also available through FGControls). For both JSBSim and the YASim C172, this property overrides the toe brakes for the main gear (actually, for YASim, it is just added then clamped).
The 'B' key now toggles the parking brake on and off. There are a couple of 2D panel issues we'll need to address: 1. the brake indicator light no longer works, because it's tied to the nosewheel (which has no brake); and 2. we need to provide some visual cue that the parking brake is set, probably by adding a parking brake instrument at the bottom of the panel (of course, the inability to taxi without full power should be a clue). I'll add an animated parking brake to the C172 3D cockpit when I have a chance, and will also try to remember to add the parking brake to the other YASim aero models unless Andy beats me to it. I haven't tried to add this to LaRCsim/UIUC yet. Perhaps someone who knows that code better could take a shot.
