Thanks for the hint. That helps. It makes sense from a developers' point of view. However ... we still have a bug from the users' point of view. The documentation explicitly mentions the case where the user has a rudder input device but lacks the skill to "handle the proper ratio" ... and recommends --enable-auto-coordination in this case. If users are required to have zero-noise ailerons and zero-noise rudders, this is quite a serious restriction. This should be prominently mentioned in the documentation. Users will not be pleased. ============= I just now spent some time looking into this, and found a few surprises. When auto-coordination is turned on: 1) The feature is implemented as an aileron-rudder interconnect with a fixed ratio (half a unit of rudder per unit of aileron) in the aileron->rudder direction and not vice versa. This is not very sophisticated or very useful. In almost every aircraft I can think of, it is literally worse than useless in cruising flight. It makes the coordination worse. If this is the desired behavior, I would hate to see what undesired behavior looks like. The documentation indicates that auto-coordination is supposed to make the coordination better. It doesn't. 2) It has the remarkable side-effect that while taxiing, you can steer by deflecting the ailerons! This is unrealistic and unhelpful; better ways of doing the steering are readily available. 3) While taxiing, you can steer using the rudder in the usual way, overriding auto-coordination ... provided you don't touch the ailerons! That is counterintuitive, undocumented, and unhelpful. The FAA says you should be deflecting the ailerons when taxiing, if there is any crosswind. You must not touch the ailerons, and must hope there is no noise on your joystick aileron axis. This is in addition to the previous requirement for no noise on your rudder axis. ================================= How hard would it be to replace all this with something useful? I notice that several of the aircraft models have yaw dampers. ------------------------------------------------------------------------------ This SF.Net email is sponsored by the Verizon Developer Community Take advantage of Verizon's best-in-class app development support A streamlined, 14 day to market process makes app distribution fast and easy Join now and get one step closer to millions of Verizon customers http://p.sf.net/sfu/verizon-dev2dev _______________________________________________ Flightgear-devel mailing list Flightgear-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/flightgear-devel
