Yaw Damper - when to use? on or off for approach?

Recommended Posts

Hello:

 

A basic question - Can someone advise whether the YD should be on or off during approach?

 

Further, is the protocol for use of the YD the same in both the NGX and NG?

 

Thank you, WilloW

YD always on in flight during normal procedures.

 

NGX is just PMDGs name for NG for FSX

 

On the ground also?

 

I ask, as I was told it should be off on the ground, on in the air, but turned off at 400 feet.

 

This said, I have not found anything substantial to support this. Thanks, WilloW

Always on, also on the ground. Don't turn anything off at 400 feet, concentrate on the approach :)

Never heard about turning it off during the approach. YD is always on, even on the groung, it's on the checklist (Preliminary Preflight Precedure - Overhead).

There are two types of yaw dampers. The 737 has a "parallel" yaw damper which can be on at all times. The pedals don't move with its operation. Another type is more common on Turboprops. This actually operates the pedals for you, and thus needs to be off for takeoff and landings.

Thanks for this information. I appreciate your time.

 

So, is there any action that requires the YD in the 737 to be turned off ?

Hmmm. Probably only a malfunctioning Y/D. There's really no other reason to turn it off. You don't want to be in the back of a -900 with the Y/D off in turbulent weather.

Yes, the "rudder" story has developed checklists calling for YD off... But that's abnormal checklists.
