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. Best things in life are free - so is FlightGear! As an instrument rated pilot, I use FlightGear

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. This is news to me. Which instrument models the drift ? I thought none did , so I created a

This is news to me. Which instrument models the drift ? I thought none did , so I created a nasal gyro that drifts at 3 degrees/15 minutes for my own use. Apparently I haven't looked close enough at the instrument code . From heading_indicator.cxx: // Next, calculate time-based precession

Don't forget to mention that one of the best features of FlightGear is that it is open source. Complete source code is available to all and we have an open community of developers that anyone can plug into and ask questions. This is less concern perhaps to end users, but still is one of our most

[Flightgear-devel] [PATCH] Improve random object selection

2010-04-23 Thread Stuart Buchanan
Hi All, As you may recall, there was a bug in the random object placement where the model selected in the case of multiple object definitions in material.xml was random, rather than seeded. This was partially fixed before the release by (I think) Erik. I've now got a better patch using the mt
