David Megginson [EMAIL PROTECTED] said: It's not mainly torque effects but the yawing moment that you have to worry about. Unless the plane is a centreline thrust, the good engine will be off to one side pulling that side forward and starting a yaw-induced roll (and if the bad one is not

It looks like there is code that is *supposed* to subtract the wind from the airspeed, but it obviously isn't working. This made me curious. Does FlightGear simulate windshear? Dave ___ Flightgear-devel mailing list [EMAIL PROTECTED]
