Hi Syd, I'm glad you're attempting this, and hope you get something useful out of it... from my (limited) gliding experiences, the local weather in FG is much too stable and predictable as you mention... and obviously there is absolutely no lift from ridges (or sinks on the leeward sides, as you also point out.) While atmospheric modelling is not exactly an easy game, I think your simple approach might be a useful and workable start and I'd be happy to help with testing if nothing else.

My idea is to calculate wind-speed-from -down , by checking wind speed , direction , and the normal of the scenery triangle directly beneath the aircraft , sampling every second or so.Also with a scenery material and time of day check for updrafts over flat country . Ive tried to find a starting point in the code , but get more discouraged as I get lost in it. Hi Syd, I tried doing this a couple of years ago. As I recall, I was able to get the normal informaton from the scenery triangle fairly easily, and calculate the up/down draft. The problem came when I tried to have the affect the aircraft. Unfortunately I can't remember where I inserted the normal calculation code. Sorry I can't be of more help - but at least you know that part of your solution is possible ;) -Stuart - This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100url=/ ___ Flightgear-devel mailing list Flightgear-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/flightgear-devel

Re: [Flightgear-devel] [Flightgear-cvslogs] CVS: data/Nasal glide_slope_tunnel.nas, 1.4, 1.5
* James Turner -- Wednesday 24 September 2008: Well, in the future, the key args for getActiveRunwayForUsage are what I said - the usage type (landing or takeoff, maybe some other flags in the future for weird stuff, like helis) and the inbound / outbound radial, [...] OK, then let's revisit the topic once there's a necessity. While we want to offer *data* even if they aren't needed yet, because one never knows what clever stuff people can do with them, we don't do the same with interface functions. There, less is more. Traditionally we only add interface functions when something can't be done on the Nasal side, or not with the required performance. Searching through a list of runways (which we have already) is rather simple. And it's done already with success. We may want to add some more data to airportinfo() for extensions of that search. At the moment we don't even have a way to query an aircraft's weight and size, so there's a limit for the sophistication of a runway search anyway. I see you don't like my long_underscored_function_names [...] That's because we don't have a single function name with underscores. It's setprop, not set_prop. It's settimer, not set_timer, etc. It's about consistency. I'm also a bit unhappy with the active in the name. You can't search for an active runway based on runway data. What is active is decided by the ATC. You can at best search for the best suited runway. :-} but I'm not a fan of script functions that take (potentially) hard-to- remember arguments: foo = airportinfo(EHAM, landing, 40.0) // 40.0 being the inbound radial in degrees Nasal TNG solves that problem: foo = airportinfo(id:EHAM, radial:40); That's assuming that the function is a wrapper for the built-in command. I guess I was thinking airportinfo was an 'airport lookup' function, I hadn't considered it returned 'everything you ever wanted to know' which seems quite ambitious. That's understandable. You haven't contributed a single line of Nasal so far, have you? :-P m. - This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100url=/ ___ Flightgear-devel mailing list Flightgear-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/flightgear-devel

Thanks for the replies folks, glad to know earlier attempts partly successful :).I'll post here if I think I'm making progress with it , but since I seem to have half a dozen projects going at once it might be sow going Cheers. - This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100url=/ ___ Flightgear-devel mailing list Flightgear-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/flightgear-devel

FWIW: I'm about to finish that, so no need to adapt your version. :-) BTW: there's now a props.runBinding() function that allows to execute regular bindings from Nasal.
