[Flightgear-devel] New idea for flightgear

2013-06-23 Thread Ashirwada Wijerathna
Dear sir/madam I am a great fan of flightgear. I would like to point out that crashes in flightgear is not simulated. so add simulated crashes in the next flightgear version. -- ASHIRWADA WIJERATHNA -- This SF.net

Hi John: snip I'm wondering if anyone has any suggestions on getting this data into the system so users can start flying over it. snip I maintain a mirror for flightgear. (ftp://ftp.kingmont.com and http://kingmont.com) You might try contacting Curtis and see how you would go about putting

[Flightgear-devel] Positioning Aircraft: accuracy

2013-06-23 Thread D-NXKT
Hello, I noticed that positioning an aircraft at FG startup with --lon= and lat= has only a limited accuracy. It seems that only the first 7 digits are read. This leads to an uncertainty of several meters/feet! For example lon=11.379070 --lat=47.306263 is needed to place our hang glider directly

Hi Tom, How have you checked these values? I've just tried it myself and in the property browser exactly the same values appear. I started FG with --lon=11.379070 --lat=47.306263 --heading=155 --units-meters --on-ground and found me at --lon=11.3791

Hi Ashirwada, this feature is implemented but disabled by default in FG's source code. To enable it, if you really want that (think twice), edit file src/AIModel/AIMultiplayer.cxx and alter the false to true in FGAIMultiplayer::FGAIMultiplayer() : FGAIBase(otMultiplayer, false) This action,

Hmm, everything is fine if I use a different plane. Seems to be a hang glider specific problem. Monitoring the latitude and longitude variabel from the very beginning shows, that both variables have at first indeed the correct values. Then the latitude value suddenly jumps from 47.306263 to

The hang glider is using the UIUC fdm, right? Perhaps that is using a float (6-7 digits of precision) to represent it's initial conditions ... or somewhere in the startup pipeline or the flightgear interface to the uiuc model, the initial lon/lat is stored as a float? On Sun, Jun 23, 2013 at
