I used this command line: fgfs [EMAIL PROTECTED] --aircraft=c172r --turbulence=0.0 This set up the winds as I wanted. However, even though turbulence was set to zero, there was still lots of noise present in the wind velocity coming from FlightGear. The wind seemed to vary +/- 5 to 10

[Flightgear-devel] Property Manager enumeration of properties

Is anyone aware of a [simple?] way to print out the property tree once it has been populated? It seems to me that there ought to be a class attribute in the property manager somewhere that is a pointer to a linked list, or a vector, or whatever, that contains the properties, each of which may

[Flightgear-devel] Short Reference Document error?

This short reference: http://www.flightgear.org/Docs/FGShortRef.pdf shows the rudder control on the numeric keypad as being the 0 and , (comma) keys. There is no comma on the numeric keypad. This is confusing. Jon ___ Flightgear-devel mailing list

[Flightgear-devel] Landing Gear Jitters: Resolved?

2005-06-19 Thread Jon Berndt
I am testing out a small preliminary fix for the landing gear jitter seen in various JSBSim aircraft. Curt has relayed that the default C-172 does have this problem - and I have now seen that. The preliminary fix does seem to have fixed that, although when brakes are applied while at rest there

RE: [Flightgear-devel] FlightGear Wind and Turbulence

2005-06-19 Thread Jon Berndt
What does FlightGear do in the way of wind and turbulence? I assume that winds are set in FlightGear in NED coordinates and that those change slowly? Turbulence is modeled in the FDMs, but parameters are passed in? FlightGear does not model turbulence itself, does it? What is WEATHER_CM?

I am debugging the gear jittering in JSBSim and I am seeing windNED spike every so often and I have commented out turbulence code in JSBSim, so I am wondering if these wind spikes are coming from FlightGear. OK, in working to fix the gear jitter I've discovered some things about the winds

WeatherCM is the old weather system that has been removed from cvs for fgfs 0.9.4. It's in the old repository's hidden Attic/. I think it's safe to remove all traces to it. m. Thanks. Will do. That simplifies looking at the code. Jon ___

Aha ? In fact the notation in the cheat sheet _is_ correct and clear, why the hell do you want to break it ? It's just a matter of point of view an I assume there are _many_ FlightGear users out there that have a comma as a decimal separator - it's just that they probably don't live in the

I was looking at the gear jitter in the latest version of FlightGear with the current C172 (JSBSim). I didn't notice much jitter at all - really very little. Is that because winds are off by default, now? Is there a particular setup where I can see it most noticeably? I have a possible fix that

It appears as though JSBSim CVS is in a good state, with the new code, and new directory structure. Notes: 1) No attempt has yet been made to test this with FlightGear - that will take a little bit of work. Things are different: the directory structure, the code, the aircraft config files,
