# Are turns, while under the control of a two-axis autopilot, uncoordinated?

Since the two axes of a two-axis autopilot are pitch and roll, when the autopilot executes a turn, is it uncoordinated since the autopilot is not controlling the rudder (yaw)?

• In larger aircraft, the autopilot is usually still 2-axis, but the yaw axis is controlled by separate yaw damper that is simply trying to keep the ball centered (approximately; the control logic is slightly more complex). It's main purpose is to damp the Dutch roll, but as a side-effect it also coordinates turns. Since it is separate, it can be used even when hand-flying. Apr 24 '17 at 18:34

That’s just for a single-axis autopilot. Your question asks about dual-axis autopilots that have another dimension in which to go “uncoordinated,” viz. pitching up too steeply for the current power setting and causing an aerodynamic stall or pitching down so as to exceed $V_{NO}$, $V_{NE}$, $V_{FE}$, etc.
