No. You'd just have to extend JSBSim.cxx so that it queries the ground cache for every gear. From there it can get all the terrain information cheaply. YASim does this, it also uses the friction values, and slightly modifies the terrain elevation according to the bumpiness value before it's used by the FDM. Try a YASim aircraft (e.g. the dhc2W) and leave the runway. Taxi over grass and into a forest. You'll "feel" the bumpiness and see it on the gear animation. The values are also interesting for sound effects. If you slide the bo105 over concrete, then the noise is louder than over grass or ice. 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=100&url=/ _______________________________________________ Flightgear-devel mailing list Flightgear-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/flightgear-devel
