[Flightgear-devel] Mapserver interface
This still is not heaven; but it is outside hell :-) In my desperate attempt to throw some usability at my mapserver I made my first attempts writing some lines of PHP: http://mapserver.flightgear.org/ You're invited to make use of this mapserver if you're uncertain about the landcover data that our Scenery is made of.

[Flightgear-devel] UIUC FDM
In the progress of testing the FG live cd (under qemu), I discovered a rather interesting behavior of the UIUC FDM. (My) qemu by default ram size to be 128mb. When I was trying to run fgfs, it gave me an exception of std::bad_alloc and then terminated. After having some hints from Melchior on what this could mean, followed by a run under gdb, it pointed me to src/FDM/UIUCModel/uiuc_wrapper.cpp line 120, which is simply a global: AIRCRAFT *aircraft_ = new AIRCRAFT; Then we check the size of the AIRCRAFT struct, and it turns out to be about 117mb. I probably don't know enough about UIUC's or in fact any FDMs' internals and so I can't say whether this is a lot of memory for a FDM or not. But having 117mb of memory allocated (or committed) at startup (this is even before main(), btw), regardless of what aircraft/FDM is being used, is probably not a good thing. Codewise, this struct is rather big... Anyway, I imagine someone who knows a bit more about UICI's code could make it new-ing the struct only when it's actually used?

This is a major difficulty that has been discussed several years now - the discussion had started long before SWBD was available. I won't be able to deliver a satisfying response to this question, but at least I might make one point clear: - VMAP0 'landmass' focuses on political boundaries and may not follow the logic that's required by a coastline (see the Toronto examples, that have been posted on this list recently, for the results). - SWBD (SRTM Water Body) shows the state right in the moment when The Shuttle came by and does not contain correction of tidal effects. These tidal effects can be huge in certain areas of tidelands ... ;-) - GSHHS should be considered to be our most accurate source of _coastline_ data but fails significantly on certain lakes (see the Toronto area as well). The problem with using GSHHS for coastlines is that chances are high that VMAP0 rivers don't end at the real coastline but instead stay inside the 'landmass' area. This had been the reason why Curt took 'landmass' for the resent Scenery release and this is as well one reason why we're running this Custom Scenery project: To allow people to correct significant river mouthes to match GSHHS coastline. This is definitely a long way to go and requires major effort but I think there's no alternative (aside from buying commercial data).

I flipped a coin, and agl-hold won! :-P No, seriously: If nobody objects I will tomorrow switch all remaining occurrences of terrain-follow to agl-hold in generic FlightGear files (but not in maintained aircraft, unless the maintainer wishes so). Rationale: - $FG_ROOT/Aircraft/Generic/generic-autopilot.xml uses agl-hold - $FG_ROOT/gui/dialogs/autopilot.xml uses agl-hold (and did before my changes) - all /autopilot/locks/altitude options end with -hold. (all heading options, too, except wing-leveler, which is understandable) Only $FG_ROOT/keyboard.xml and these aircraft use terrain-follow in at least one *.nas or *.xml file: - AN-225 - BAC-TSR2 - A-10 - B-52F - YF-23 - seahawk - MiG-15 - TU-114 - Hunter - CanberraBI8 m. Apart from the Hunter, which Vivian did, and the seahawk, which Vivian has done a lot of work on, the others were all done by me. A simple search replace on 'terrain-follow' /should/ work but will result in some funny property node names. I'll go through them manually and get updates out. Vivian: do you want to do the seahawk or shall I? I guess we need to rationalise the seahawk anyway.

RE: [Flightgear-devel] Two different problems with c172p and c172r
Thanks for the file. It fixed the seg fault. But C172R seems to suffer the same lower-than-RL max RPM as C172P (2200 vs 2400), and as such cannot climb at the expected rate. Do they share some engine spec file that may have been modifed recently? Yavuz Onder I don't think so. I've got a fresh build from a couple of days ago (from FlightGear CVS). I'm showing no differences between my base package and CVS for the aircraft and propulsion. Using the default startup: fgfs --timeofday=noon I get 2500 rpm and 1000 fpm climb rate off the runway at 70 kts. I don't know how close that is to actual.
