Re: [Flightgear-devel] 0.7.9pre2
Some time ago a big company, which shall remain nameless, bought 3dfx. They have now opted to yank the 3dfx site, and all support for old cards with it. (That alone is reason enough not to buy their cards.) Yes, I wish there was more choice in the 3d graphics world. You could always try an ATI card. People have been reporting pretty good results with their cards. especially me, crying very loud :-) The first PeeCee is set up, dedicated to run FlightGear, is using a 3dfx Voodoo3 PCI with 16 MByte.

Re: [Flightgear-devel] Crashes if no scenery file at startup location
I'm only getting this with JSBsim right now. Maybe I've got something screwed up here anyone else seeing this? The symptom is that if I specify an airport that is not in scenery the simulation comes up correctly momentarily and then tries to load a tile and does the fatal bogus long/lat error. This is the output using --airport-id=EHAM: http://www.spiderbark.com/fgfs/scenerynotfound.txt Note that this problem does go away if I set --altitude=0 or some other small number before starting. The problem may be stemming from an improper altitude sent to the FGInterface bus or something ... I don't know. Tony: if we are given an incorrect unsynchronized altitude data what does the trim routine do? I am thinking this is due to differences in the way JSBSim is started up but not explicitly in the JSBSim code. Could be a bug in the way altitude is figured for some airports?

* [EMAIL PROTECTED] (Curtis L. Olson) [2002.02.14 09:58]: The manual is really quite extensive and impressive and represents a very large amount of work. It is definitely worth reading through. I learned several new things myself. :-) First, Michael and Martin have done a fabulous job. Kudos to both of you for a job well done. Please take a moment to read through it if you can and send Michael or Martin and suggestions or fixes. Only little stuff can be fixed for 0.7.9 but larger suggestions can be considered for subsequent releases. I've looked through some of the manual today (don't tell my boss ;-). Here's some notes (I converted the PDF to Postscript, so the page numbers may be off): - p29: I believe binaries are also shipped with SuSE Linux, though I don't think you need to discuss how to install them. - p62: first line reads Alls this project goes back Need to rephrase that to make sense. :-) How about The FlightGear project goes back - p65: the operational radio stack section seems out of place. IMO it should come later to keep the items in chronological order. - p71: my entry needs two changes: I would prefer to use cameron at unbeatenpath.net in that situation, and the word administration needs to be administrator. - p75: Section A.3 starts out with At first:. I think that can be removed. In the same sentence, I'd change until this point to up to this point. I'd start the second paragraph with Despite the current set of features, or Despite all of the progress so far,. Hmm, I'm finding stuff left and right. I'm going to have to be a good husband tonight, but I will try to make a point to read through some more of this and send any revisions to Michael.

Re: [Flightgear-devel] Crash when KMYF not KSFO
Alex Perry writes: The current CVS hangs for me when ground started at KMYF, yet is fine at KSFO. Immediate crash. It's a long way to commute, could we fix that sometime? Hmmm, I can verify this same problem here too. With fgfs --airport-id=KMYF : - Flightgear starts up. - The JSBSim constructer is called, and the aircraft config file is loaded. (But JSBSim is not init'ed until after the scenery loads so we can pass in a proper ground elevation to the trimming routine.) - FlightGear continues to load/init various systems. - FlightGear finally gets around to loading the local scenery tile and a valid ground elevation appears on the bus. - FlightGear determines that it is now ok to run the JSBSim init() routine. This triggers a ground trim and JSBSim prints touch down reports and a bunch of other output and finally returns with: Trim successful JSBSim State Trim complete - This is immediately followed by a long sequence of: 0: GEAR_CONTACT 1 1: GEAR_CONTACT 1 2: GEAR_CONTACT 1 3: GEAR_CONTACT 1 4: GEAR_CONTACT 0 5: GEAR_CONTACT 0 6: GEAR_CONTACT 0 7: GEAR_CONTACT 0 8: GEAR_CONTACT 1 etc. . . . 56: GEAR_CONTACT 1 - It appears that JSBSim has trimmed the aircraft to below ground so FlightGear notices this and attempts to force JSBSim to use a higher elevation. This triggers another ground trim, again which ends up several meters underground, again causing FGFS to try to force JSBSim back up above the ground. - There seems to be a long exchange of angry words with subsequent JSBSim trims failing. - This is followed by JSBSim spewing out 985 successive GEAR_CONTACT bool messages. - Again FGFS tries to force/coax JSBSim up to ground level. - More of the same with JSBSim triming under ground, the gear code goes berzerk, spews 100's more GEAR_CONTACT messages. - Eventually JSBSim flags a CRASH. - JSBSim is hosed at this point and copies a completely bogus lat/lon onto the bus. - The flightgear tile pager sees that we have moved to a completely impossible location, flags a non-recoverable error and exits the sim. Wow, that was really ugly. It happens very quickly, and most of those messages scroll right on by before you can see them if you don't run the output through less or more or something similar. So it appears that at least for KMYF, JSBSim and FlightGear are having a very strong disagreement over the elevation of the ground, and neither is willing to budge. Sounds like two typical flightgear developers. :-) I haven't been able to reproduce this at any other airport I've tried, only KMYF. Ok, after all that, I tried the same thing with the YASim c172 at KMYF and something is wierd at KMYF. YASim started just fine and took off fine, but the entire time, FGFS was spewing message about being below ground. I wonder if it is a problem with the scenery models right there? Hmmm, this appears at the moment to be some sort of flightgear problem??? Ok, looking further, it appears that nothing, no place, no where is setting the runway elevation any more ... it get's initialized at startup, but then never is updated as the aircraft moves. That is really odd ... what got sliced out of the code? It's been a while so I don't remember where this was supposed to happen. The view code has a bit of a hack to force the view height above the ground so it's hard to notice. This is really weird. In theory, you'd see very strange effects if you started at a lower elevation airport and flew to a different elevation aiport and tried to land. Ok, there is something really strange here, probably because things were changed without a proper understanding of how everything worked together. My mind is fryed at the moment looking at this stuff. JSBSim seems to be doing the right thing *except* for at KMYF. YASim assumes that the runway altitude will get set for it externally, that makes a lot of sense, but apparently isn't the case. This sucks.

Curtis L. Olson wrote: Ok, looking further, it appears that nothing, no place, no where is setting the runway elevation any more ... it get's initialized at startup, but then never is updated as the aircraft moves. Ah, which explains why I've never seen this. I only ever bother testing in the default scenery (I mean, I live here, right?), where all the useful airports are essentially at sea level. I'll try to remember to move around more. Ok, after all that, I tried the same thing with the YASim c172 at KMYF and something is wierd at KMYF. YASim started just fine and took off fine, but the entire time, FGFS was spewing message about being below ground. I wonder if it is a problem with the scenery models right there? Oh, and a tangent: what is the purpose behind the code in main.cxx that detects aircraft below ground and resets the elevation accordingly? One immediate bug is that it's not strictly correct -- the aircraft's position is by convention its nose. It can easily be in a crashed state with the nose sticking up in the air. There is a hard-coded 3m guard band in the code that presumably is intended to correct for this, but that can break for big aircraft (747) where 3m is juse noise. I actually have it commented out in my source at home, because it interacts badly with the crash detection. It's entierly possible for the aircraft to slip below ground to fgfs but not to YASim (YASim only checks the gear positions right now), resulting in a non-crash. The aircraft lawn-darts at 600 kts and then drifts slowly over the ground, still reporting a huge airspeed. So far as I can tell, there are no bad reactions to removing the check entirely.

The problem seems to be somehow at startup/init time. Very strange and confusing ... I don't see any evidence of a scenery model problem around KMYF. I have a guess about where the problem might be -- I recently modified JSBSim.cxx to copy start-up settings over from the FlightGear before initializing so that we'd get the initial engine values (RPM, etc.) into JSBSim. That might explain the tug-of-war; I'll look at it now. Nope -- that wasn't it (so I'm off the hook for now). Note that there is no problem with It's the JSBSim trimming routine. This works: fgfs --airport-id=KMYF --prop:/sim/startup/trim=false This doesn't work: fgfs --airport-id=KMYF --prop:/sim/startup/trim=true Note that the opposite applies everywhere else; i.e. fgfs --airport-id=KSFO --prop:/sim/startup/trim=false *doesn't* work (the plane flips over).
