Yaw Damper

[Arthur Alspector]

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,

well, in a 737-500 checklist (for the dreamfleet cockpit) the yaw damper is
switched on in quite an early stage.

something like that:
(battery column from top to bottom) battery, some checks, ground power, bus
transfer, ...
(left column from top to bottom) ..., spoilers, ..., yaw damper, ....

I wrote it by memory so it might not be absolutely correct, but it should go
in a quite similar order. The YD isn't turned off until shutdown (don't know
about non-normal checklists).
