If you're just running it, then the aircraft files already take care of everything for you. Just use --aircraft=xxx-yasim (where xxx can currently be c172, c310, dc3, a4, harrier, or 747). The only command line argument that will affect the FDM as such is overriding the /sim/fuel-fraction property. The jets, especially, have different performance with different fuel loads. Just use: --prop:/sim/fuel-fraction=0.2 (for example) to get a reasonable "approach" configuration. With the jets, you'll also want the HUD turned on as there aren't any panels yet. I use: --enable-hud and --disable-panel for these guys. There's also a complication with the Harrier. You'll need to map a joystick axis to the /controls/thrust-vector[0] property in order to work the thrust vectoring. A keyboard interface would be possible too, but due to the lack of a panel there's no feedback to the user about what the setting is currently. I use one of the rotary dials on my Saitek X45 (OT note: a *GREAT* joystick, if anyone is interested in recommendations) and it works great. I've been playing/practicing with the Harrier a lot recently. I really should write up a "training guide" or somesuch, for folks just getting into it. The learning curve on the VTOL stuff is nasty and steep, kind of like being a real life test pilot on the things. Loads of fun. I can *almost* reliably land vertically now -- but hovering still eludes me. Once I move away from the location I picked to land on, I have to fly off and re-do the whole approach. Oh, and Gene: I've got an F-15C for you (attached) but I'm not entirely satified with it. What's happened is that the "parasite" drag has to be pushed so low by the solver in order to match the mach 2.5 cruise number that the induced drag (that is, the backwards component of the lift at non-zero AoA) ends up dominating. The aircraft bleeds speed *fast* in a turn, much faster than the A-4, which has a broadly similar wing configuration and loading. I'll need to put in supersonic drag handling before this works really well. But it takes off, lands, and accelerates more or less like the real thing. Andy -- Andrew J.
