When should the 'yaw damper' be deployed in the Boeing 737 and 777? I
didn't notice the button in the 747. I have used it flying the Cessna 182S
and it works well to stablize the yaw in a crosswind, but I haven't figured
out if it's required in the large aircraft, especially when the autopilot is
engaged.

Thanks in Advance,
