OK, I had to go look this one up. It turns out that there is a *boolean* property controling engine-on for the helicopter FDM, which is wired to the engine[0] magnetos property by the FDM configuration. This in turn is driven via a timer by Melchior's Nasal code in bo105.nas. This inspects the /sim/model/bo105/state property to determine what the current state is, and to watch for changes. The default startup state defined in bo105-set.xml is "0", indicating off. You should be able to change /sim/model/bo105/state to "2" to start with the engine on, either in bo105-set.xml or (I think, if I understand the precedence correctly) your preferences.xml file, or the rc file, or the command line. But again note: this is a boolean property. There is no actual suppot for engine starup or shutdown in the helicopter FDM (which, now that I think about it, serves as good evidence that an ugly eye-candy hack is in fact an acceptable implementation of startup/shutdown for YASim. :) Andy _______________________________________________ Flightgear-devel mailing list Flightgear-devel@flightgear.org http://mail.flightgear.org/mailman/listinfo/flightgear-devel 2f585eeea02e2c79d7b1d8c4963bae2d
