This is a perfect example of a thread that demonstrates that many pilots flying corporate jets have absolutely NO idea what their feet are for!
If one is unable to detect whether the YD should be ON or OFF for a landing, they should not, IMHO, be flying anything more than a Cessna 152! Yaw damper is NOT designed to assist flight at approach speeds - in fact it hinders.
By all means follow the destructions (sic) contained within your FM's, but try to land with the YD engaged in anything more than a 5 kt X wind (irrespective of what the FM states), and your feet will be be working far more than they need to be - unless you are of the type who is happy to slap it down any old how.
YD is a pain in the arse for anyone who wants to hand fly an airplane at slower than cruise speeds - and especially for pilots who know what the ball (balanced flight) means.
And in GO-AROUND MODE it's a night mare!
