Can't hold a vertical climb in the f15 and can only get to mid altitudes in the teens with 747 This is the second time this has been reported, but I can't reproduce it. Your note later on, however, looks like a good clue: does each each engine have a throttleor is it a single command for all four(two)? They are separate properties -- the left engine(s) use /controls/throttle[0], while the right are controlled by /controls/throttle[1]. This is handled in the aircraft XML file. I didn't define four separate controls for the 747 because I was lazy; making that work would require changes to the default control mappings. If your throttle is only jiggling the first property, then that's the bug right there -- you're only getting half the thrust. engine egt is given in degrees centigrade and fuel-flow for turbines is usually given as #/hr (1 gal ~ 6.5 pounds) The current egt property hands you fahrenheit. Fuel flow is in gallons per hour. Especially with the fuel, I'd agree with your choice of units; but nonetheless that's what the standard currently says. Maybe we should go through and audit the FDM outputs for a sane set of baseline units. Engine data is a little screwy. running jbsim for the c310 no data comes across and for yasim-747 the zeroeth values are missing. Not sure i've got this properties thing all figured out yet. Missing? Weird. There were some changes here recently that might be causing this. David was kind enough to give me a heads up about the changes to the YASim code, but I ignored it. :) I'll take a look.

BTW, Alex, will you be at LinuxTag? I'm tempted to have one of the non-European developers as the lead presenter (and then beg assistance with travel) if someone has the time and interest. Good point - I did not want to exclude the non-europeans with my list. I am sure that apart from your own talk you will also enjoy the other talks and the show very much. If we do that, it's important that the presentation topic is one that can be given by a European dev should the travel intent hit a last minute problem. Well, I will certainly be at the fair. Two years ago, when I was there as visitor, it was *very* interesting. Also, while my Linux endavours have further declined lately, I am still very active and interested in open source.

[Flightgear-devel] 0.7.9 release schedule
I really, really, really want to roll out the FlightGear-0.7.9 release soon. I haven't posted an official release time table yet, but I will do that in this message. John Check writes: For sure. Just make sure you guys don't commit any major breakage to CVS this week ;) LWCE/New York is this week and as per John's request, perhaps it would be a good idea to go slow on a lot of major CVS changes to keep from complicating their lives. However, John, no matter what we do, it would be wise to get the latest version running before the show starts and just stick with it, warts and all. Tracking cvs and rebuilding the binary on the booth demo machines in the middle of the show is just asking for trouble, wierd problems, and uh ... it just was working or I don't know why it just did that type moments. Get a recent version working, and then just stick with it. So here is my proposed schedule: Now - Feb 8 (this week and next) is the last chance to submit new features for the 0.7.9 version. Preferably I'd see more bug fixes than features in this time. Feb 9 - Feb 15: Everyone should be building from cvs and the trial tarballs and reporting any bugs, build problems and platform incompatibilies. Try it out on your platform and compiler and send in bug reports sooner rather than later. If you don't, and 0.7.9 has problems on your platform, don't come complaining to me afterwards. :-) Feb 16: Official 0.7.9 release day. Does this schedule sound reasonable? My time is very limited these days, but I will do my best to stick to this timeline. If everyone agrees, I will go ahead and cast it in stone. I will do everything I can to look at and apply everyone's patch submissions in time. Also be aware that David Megginson has cvs write access so you can send reasonable stuff to him as well. Be aware that neither of us blindly commit patch submissions and we evaluate your submission to make sure it fits in the overall scheme of the project. We try to fix things as much as possible if not, and only reject patches as a last resort.

[Flightgear-devel] Httpd port binding bug
I've found a bug in the httpd server, but I'm too timid to propose a
patch to Curt. :-) Here's the deal:
In httpd.hxx we have:
HttpdServer ( int port ) {
open() ;
bind( , port );
listen( 5 );
printf( Httpd server started on port %d\n, port ) ;
}
The problem is that we don't check to see if the bind() actually worked,
so if the port is already taken (or something else goes wrong), we don't
deal with it.
I'm pretty much a dummy when it comes to C++ classes, so I'll leave it
up to someone else to propose a fix. Oh, and this problem exists in the
jpg-httpd server as well. Thanks
