That's the least of my worries, for several reasons. I've always thought the 200-ft business was a weird optimization, especially since other properties such as gear-extension-norm are recomputed at frame rate at all altitudes. And that is the solution for retractable-gear airplanes: forget about wow and just look at gear-extension-norm. I just hope the latter never gets "optimized" into never-never land. At one point the wow property was fixed so that it would be updated at least once above 200 AGL, but the fix evaporated. And I don't care anymore. I'm happy to use gear-extension-norm. Far more troublesome is the behavior of presets-commit, which still has a tendency to put the FDM into unrecoverable states, such as uncommanded vertical pitch attitude and zero frame rate. ------------------------------------------------------------------------------ _______________________________________________ Flightgear-devel mailing list Flightgear-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/flightgear-devel
