Dutch Roll

[Edge540]

The corrective action for dutch roll due to yaw-damper loss would be specific for each aircrfat type, but generally...

- Re-engage YD and AP
- If that doesn't work, keep your feet off the rudders
- Correct roll w/ short, brisk aileron inputs
- Descend out of the flight levels.

Seconded.

Some airplanes will do it no matter what you do (the CRJ comes to mind). Talking to a CRJ test pilot, she said that the plane will wiggle all the way down until your wheels touch. To minimize it, like you said, use aileron inputs. DON'T USE RUDDER. Use adverse yaw to your advantage.

At Riddle our advanced jet transport aerodynamics professor told us it the above situation ever occurs to just make sure the autopilot is engaged and that would take care of the problem.

I'm glad you riddle diddles are still taught stick and rudder skills....

Lord help us all...

See now I feel robbed for not having gone there.

So a dutch roll only happens in the flight levels? What if you're doing single-engine low altitude maneuvers (i.e. instrument approach), can you get into a dutch roll by adding power on the good engine? Or is that just single engine aerodynamics?

no rubber!!!! keep your feet off, will make it worst

Doesn't anyone see how this person wrote "no ruBBer"? I mean, seriously, we should require everyone who posts here, to have at least graduated elementary school!

My theory is that he was looking at the Jailbait or Edge540 Avatar while typing.

Classic Freudian Slit.

Ok, ok, I see, and yes, that Avatar does make one's mind wonder. I'd say a case of Hypoxia, Stagnant (or Ischemic) Hypoxia to be more exact, just a lack of blood flowing to the brain due to a 'local' restriction of the blood flow caused by a major BONER!

In "Fly the Wing," Webb recommends, in part, blocking the rudder, not necessarily keeping feet off. He further states that rudder input should not be used, as Dutch Roll induces some heavy stresses on the vertical fin.

He also says up front that recovery from Dutch Roll is different for every aircraft, and that he references a DC-9-30.
