Re: [Flightgear-devel] engine reconfiguration?
This morning I did a git-pull and make. I observe that the new version executes in 855 megabytes under conditions where the previous version from a week or two ago executed in only 450 megabytes. That seems kinda extravagant. Is everybody else seeing the same thing? Specifically I'm talking about the number reported by top(1) in the VIRT column. Other tools report slightly different numbers.

Re: [Flightgear-devel] v1.9 screenshots
Hi all, ex-subscriber back in the fray : it's been years, and my hat off to all involved for the leaps and bounds in bringing FGFS so far from its humble beginnings :) In answer to Curt's request for screenies, I have set up a public web album on my Picassa page where I'll be uploading screenshots, both of "eye candy/PR nature" and to illustrate problems (might put the latter in a Glitch subfolder, or somesuch) All the screenshots (by default, my uploaded pictures are NOT) will be under the Creative Commons license so feel free to use them :) (remix, commercial use, share alike are the conditions/rights) http://picasaweb.google.ca/noxiousnic/FlightGear Not much yet, but I'll be uploading regularly. Not sure if I'll keep uploading full size images, as they eat up space quite fast. We'll see :) Cheers, and happy flying to all !

[Flightgear-devel] engine reconfiguration?

That seems like a reasonable question. I have some related questions. For one thing, in a Real World C182 at 2000 feet, at economy cruise with 18" MAP and 2100 RPM, the engine puts out 45% of rated power with a BSFC of 0.445 ± 0.010 lb/hp.hr or thereabouts. See e.g. the power setting table on page 5-17 of the POH. So the question is, why does the FlightGear model c182rg, with the new FGPiston, put out only 25% of rated power under the given conditions. And why is the BSFC up around 0.7? Pilots tend to notice when the power output is too low by almost a factor of 2, and when they can only fly 2/3rds as far as expected on a given amount of fuel. The deeper question is, why are we playing whack-a-mole in FGPiston.cpp? That is, what's the point of replacing one wildly unphysical throttle model with another? Why not do it right? -- The old model was messed up with regard to power and RPM. -- The new model is messed up with regard to MAP and fuel flow. This suggests it may be a bit premature to run around changing all the .xml configuration files for the FG aircraft. Again: What's the point of replacing one wildly unphysical model with another ... especially given that a well-founded throttle model _that agrees closely with Lycoming factory data_ was worked out some time ago. http://www.av8n.com/fly/engine.htm The c++ code to implement this exists, too.

Hi Rob, It appears that the code that computes how many rings of tiles to load is perhaps not doing that correctly any more? Originally the code would ensure that enough tiles were loaded to cover the visibility range so that the end of the world would blend seamlessly into the fox color which matched the base of the sky color and you didn't see these artifacts.
