And you also checked that approach glide angle isn't used? Otherwise, the new default cruise angle (0.0) might not match the original approach angle setting... Anyway, we've committed the patch since it was assumed to not cause major differences. These bugs have been there since the beginning of YASim - so for 10+ years. If it's confirmed that the patch actually caused major differences, then we should "improve" the patch. We could restore the old "buggy" behaviour by default and only use the new "correct" FDM configuration behaviour for new FDMs, e.g. add a switch, such as a new FDM parameter or YASim FDM version number in the xml file to enable the bugfix. Heiko, and anyone else: if you think there is a major change, then directly compare the FDM behaviour with and without the patch - and let us know if there was trouble. And that's the relevant patch: http://www.gitorious.org/fg/flightgear/commit/7f5a0e35184677c21f1eafdfbe6438eb644cdbff cheers, Thorsten ------------------------------------------------------------------------------ Benefiting from Server Virtualization: Beyond Initial Workload Consolidation -- Increasing the use of server virtualization is a top priority.Virtualization can reduce costs, simplify management, and improve application availability and disaster protection.
