No, YOU go look it up. Use F-4 as you suggested. You will find that fugoid
refers to a pilot's unintenional over control in pitch. You will also find that
this can lead to PIO.

The phugoid is pilot out of the loop only. PIO is pilot in the loop
only. It's absolutely certain that the phugoid and PIO are totally
unrelated.

Back to the subject at hand the yaw damper is used on big airplanes like the
KC-135 to reduce dutch rolls. It has nothing to do with coordinated turns.
Those har handled either manually or with AFCS.

Dutch roll is a mode, not a maneuver. There's only one per airplane.
And the yaw damper is involved with adverse/proverse yaw and the
spiral mode, too.
