Those are very aircraft-dependent. Many older aircraft have hand-operated flaps, and most retractables (I think) have a manual override for the gear. In my limited experience, only the newest 172's (i.e. the 172R) have fuel pumps at all, though they're probably more common on bigger planes. > This has flight model implications. Yes, but not much; we just have to have the FDMs read from /systems/flaps/position rather than /controls/flaps, etc. > Likewise, if the master-bat switch is off and the master-alt switch > is off (or the engine is not running) and there is no external > power, then the starter motor won't engage. Again, this logic should probably be kept out of the FDMs; we can simply tell them whether the starter is engaged. > > They should be parameterized in the XML instrument config file so that > > the aircraft file can plug the right instrument into the right bus. > > Note how some instruments are already parameterized to use different > > engines or receivers. > > I never quite got the hang of your xml parameters ...

I'm not suggesting putting this in the panel config but in the aircraft config -- that's where we tie all the parts together. It should be easy to connect any device to any bus in the *-set.xml file.
