B737 -300 Yaw Damper inop
 

Hello all,

If the yaw damper is inop what are the restrictions imposed as a result-Height/speed etc.
The Max speed for example, I thought that it was 0.74 but that is for the mach trim fail condition.I Cant seem to find this info anywhere.
Thanks and safe flying

Try your operators MEL, sure it will have the item in there (cos it's in mine ;))

Cant find it in our MEL either.
What are the limits if you dont mind me sking SZ.

try Part B Section 9 or your Aircraft Flight Manual

If you look in the NNC 9.24 you just have a limitation to not use more than flap 30 if crosswind exceeds 30kts... I guess there is no max. speed limitation since nothing is mentioned in the NNC nor under limitations.

That all sound confusing enough to `bamboozle` him tomorrow. Thanks for that. Il give it a good read b4 next sim.

(if i can help you guys out with anything just ask, like flap speeds, max. weights, cross wind limits etc!!) ;)
