I don't know if this has been been incorporated into Aircraft autopilot's but on any *good* marine autopilot the amount of damping is adjustable so as to be able to tune the AP for the current enviroment Cheers Norman _______________________________________________ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
