Best things in life are free - so is FlightGear! As an instrument rated pilot, I use FlightGear regularly as a procedure trainer. What makes FG outstanding is, that it models not only the regular behaviour of systems but also the system errors. That is gyro drift, compass errors and side lobes on ILS signals to name just a few. Changing weather conditions are very important for me, too. As in real life the wind is usually not a constant number but sometimes vary in speed and direction and may be gusty. The ground relief induces updraft and a very new feature even introduces a simulation of local weather phenomena like thermal lift, local rain showers or frontal systems, based on ground relief and ground cover. Along with a simulation of structural and system icing, "raw data" aka non- autopilot ILS approaches easily result in a 100% pilot load factor.

Re: [Flightgear-devel] FlightGear's Best Features
We actually try to emulate the aircraft's systems (vacuum, pitot, static, electrical, etc.), so failure modes are much more realistic. Instruments update more realistically, with suitable lags and other errors. MSFS X has improved its flight models, but in general, I still find that both JSBSim and YASim models often feel more realistic (JSBSim is better in regular flight, but YASim sometimes does a better job around stall, spin, etc.). Easy to set up for the command line, so you can launch straight into a practice approach without clicking through a bunch of screens (and can randomize things like wind).

[Flightgear-devel] FlightGear's Best Features
Hi All, Today at work I ran into somebody who writes a column on flight simulation for the Dutch aviation magazine "Piloot & Vliegtuig" (Pilot and Aircraft), a magazine for real life pilots. Although he knew about FlightGear, he wasn't very aware of the details of the program. He seemed to be interested in the possibility of writing a column about FlightGear though, so I promised to send him a brief list of unique features of FlightGear that are predominantly of interest of real-life GA pilots, and which can't be found in Microsoft's FSX. In addition, I'll probably give him a tour of our lab's setup, once that one's fully up and running again. Although I have a fair idea what those unique features might be, this might be an excellent opportunity to incorporate some input from real-life pilots. Any suggestions are welcome though.

[Flightgear-devel] landmass geometry shader rewrite
Hi, I hacked on the landmass geometry shader a bit. On my machine I got the frame rate to improve from 14 fps to 52 fps using the ufo at ksfo. This technique may be promising, although it could certainly stand some new textures. Anyone playing with geometry shaders in the terrain (and also models) should follow the example of landmass-g.vert and landmass.geom. Let me know if I broke anything in the graphical appearance, or if any OpenGL problems are introduced.

[Flightgear-devel] Enable headtracking in FlightGear?
Hello FlightGear developers, In the FlightGear forum I stumbled upon a request from users, to enable head tracking in FlightGear (head tracking that is i.e. provided by Freetrack or TrackIR). Until now, I found no evidence that someone has embraced this request, so I would like to jump in... As you may know, the mentioned 'head trackers' have one great disadvantage: they require the user to wear a hat (or something similar) with Infrared LED's attached to it, to enable tracking. Recently I have made a head tracking program, based on the FaceAPI from SeeingMachines, which ONLY requires a simple web cam. By now, we only support the Freetrack-protocol (which is open-source) and are seriously testing it with ArmA 2 (actually, the first attempt gives really promising results). On the FlightGear forum, I found a reference to a program made by Anders Gidenstam (http://www.gidenstam.org/FlightGear/HeadTracking/) in which he states that it is possible to send UDP-packets to FlightGear, with head tracking data in it. I am currently implementing his information in my program (which I call FaceTrackNoIR, by the way) and I think I can start testing the results soon. There is, however, one problem: I have no experience whatsoever with FlightGear. Could someone tell me, in a brief manner, how I can enable FlightGear so that it will listen to my UDP-packets? It would also help, if someone could tell me what data FlightGear expects in the packets... Thanks in advance.
