Would it be a first if FlightGear implemented a real-time AI flocking bird hazard? ;) Dave Martin Anyone got any bird 3-views? ;) LeeE Not exactly a 3-view, but there is a well-done open source game called Scorched3d that has 3D flocking objects amusingly called boids. Boid types are bat, seagull, AH-64, and F-18. Go figure! Each has a 3D mesh and a bitmap skin. These flocking objects have no role other than eye candy, but they are cool. The whole game has lots of great eye candy and fun physics.

For the most part, starting a jet engine is a no-fuss, no-muss proposition. You turn on the power, push the start button, and bring the throttle to the Idle Stop when it shows some small value of RPM. The fuel control takes care of the rest. That's pretty much the case for anything but the first Me 262s/Meteors/YP-80s. Occasionally you might have a fuel booster pump, or separate switch for the ignitors, but that's about it. Unless you want to be logging Hot Starts and Wet Starts, there's nothing horribly inaccurate about just pushing the button or advancing the throttle, and a few seconds later it's idling at 10% thrust. (Somewhere around 35-40% RPM) -- Pete Stickney ___ Flightgear-devel mailing list Flightgear-devel@flightgear.org http://mail.flightgear.org/mailman/listinfo/flightgear-devel 2f585eeea02e2c79d7b1d8c4963bae2d

Digital autopilot. With help from Roy Vegard Ovesen, I have managed to get the Digitrak autopilot working in a minimal way. It will hold the heading you select using the GPS to drive the autopilot. The files are available at http://www.city-gallery.com/vpilot/flightgear/ download the latest version (0.0.3). Let me know what you think.
