Re: [Flightgear-devel] Aircraft start up postion issue.
Hi all! This issue still exists. The YASim FDM places the datum of the aircraft at the end of the runway as startup position, which means that all aircraft with datum=nose start behind the runway. Maybe we should use the CG of the aircraft as reference point or calculate some offset to the existing solution, as some airports are unusable.

Re: [Flightgear-devel] Aircraft start up postion issue.
I guess we should just move the vrp from the nose to the tail of the aircraft. It doesn't matter where the vrp actually is, as long as it aligns with the FDM reference point. It's a pity that this didn't occur to anyone when we were discussing the vrp issue, but then no one's perfect. Adjusting the vrp is really quite trivial to do but can be very time consuming if there are lots of animations to change - the AN-225 model file is 4000+ lines and the SU-37 model file has 3800+ lines :( LeeE On Tuesday 29 April 2008 10:46, Markus Zojer wrote: Hi all!

Cheers, Chris Depending on the aircraft, a work-around might be to start with zero fuel. This should reduce the weight of the aircraft, making it less likely to break the U/C when it drops on to the runway. You can then fuel the aircraft up from the menu. Obviously, a proper fix would be better. LeeE - This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event. There's still time to save $100.

Re: [Flightgear-devel] [patch] Get rid of pthread
- Benoît Laniel a écrit : This is an area where a commit now, test later philosophy could hurt the project because thread related problems can be so nasty to debug. Maybe I should have stated that I didn't know if it was robust. I surely agree with you that this patch should be for testing purpose only. I posted it since I've used it for 2 weeks now and had no problems. Again, I'm no threading expert but I thought some people would be interested by a first draft. Perhaps you could begin by explaining the problem you are going to solve, and why your way is better. -Fred - This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.

I know you are not suggesting this, but this is an issue with something else. Jon - This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.
