There is a tiller on the captain's side that acts like a steering wheel on the ground. The rudders do turn the nose wheel to a limited degree for use on the runway.

Hi Salim.

On an airliner, the pilots can "Bank" the aircraft into a turn by using the ailerons (turning the control column wheel), or you can "Yaw" it into a turn using the rudder (pushing your feet on the rudder pedals). However, in order to make the turn co-ordinated (meaning a turn without slipping or sliding), the pilots move both the ailerons and the rudder at the same time.

I hope this helps.

Salim,

You're not planning anything, are you?  Smile/happy/getting dizzy

Sorry, after everything that's been happening, I'm a little paranoid.

But on a modern aircraft aren't the aileron and the rudder auto coordinate?
i mean if you turn the control column wheel, it doesn't turn also the rudder? on a 320 for example?
thanks

Hi Salim.

I would not be surprised if modern airliners do have the ability to couple the rudder and ailerons together. However, I believe the pilots would have to be able to dis-engage a coupled system in order to fight a crosswind on final approach.

For example: Lets say the pilots of an airliner (or any aircraft) are on final approach, and they have a quartering front crosswind from the right at an angle of 50 degress to the direction of flight. The pilots would have to either "crab" into the wind using right rudder (with a little left aileron input), in order to track the runway centerline, or they could perform a "forward slip" using RIGHT aileron and LEFT rudder (cross controlled) to stay on the rwy heading. I myself use both of these techniques to fight a crosswind during final...as do most pilots.

As you can see...in this example, the ailerons and rudder could not be coupled, they would need to be independent.

Perhaps an airline pilot in the forum can let us know how their aircraft works in this area.

Hi all,
To provide the turn-coordination there is a yaw damper.
This deflects the rudder in a coordinated turn. The rudder deflections are very small in this case and also the rudder pedals do not move along.
To compute the deflection the yaw damper gets its information from accelerometers and/or IRS.
Also the yaw damper deflects the rudder in case of an engine faillure to compansate.

JetBlue-320, XFSUgimpLB41X and Mirrodie was that really necessary? I suggest an apology.

All the best
Mike
