B-52 Re-engining?

What came out of the A-300 acident was both large
transport manufacturers saying pilots should not use the rudder under normal
operations.


So one doesn't use rudder when doing a manual turn as one does on every other
aircraft made? If AFCS isn't engaged one has to use rudder to control slip in a
turn. Ever heard of the expression "step on the ball?"

The YAW damper moves the rudder for the airplane, no human workload is
involved.

The only way to disable the automatic YAW damper is to pull the circuit
breaker.

Ever heard of a fugoid? This is an F-4 related question, so don't blow it.

What does a tendency to manually over control in pitch have tp do with yaw?

Nope, go look it up.

No, YOU go look it up. Use F-4 as you suggested. You will find that fugoid
refers to a pilot's unintenional over control in pitch. You will also find that
this can lead to PIO.

Back to the subject at hand the yaw damper is used on big airplanes like the
KC-135 to reduce dutch rolls. It has nothing to do with coordinated turns.
Those har handled either manually or with AFCS.

Have a nice day.

No Dan, I am not going to teach you basic electric flight controls.

I have been more than patient with your childishness.

The phugoid is pilot out of the loop only. PIO is pilot in the loop
only. It's absolutely certain that the phugoid and PIO are totally
unrelated.

Dutch roll is a mode, not a maneuver. There's only one per airplane.
And the yaw damper is involved with adverse/proverse yaw and the
spiral mode, too.

The yaw damper does move the rudder, but its function is not to keep the ball
centered. Its function is to reduce yaw oscillations around the [normally 0]
slip angle induced by the current airplane trim. Only if there is an active
3-axis autopilot will the rudder be trimmed automatically. There is NO
automatic rudder trim in the 747-400 except during autoland operations below
1500' AGL.

The YAW damper also co-ordinates turns and cancels fugoids. It is not an
optional thing, except where much vomiting is considered desirable.

You are as usual, attepting to change the subject, Weiss.

There is NO
automatic rudder trim in the 747-400 except during autoland operations
below
1500' AGL.

The automatic YAW damper is always there on the 747-400.

Please expalin what automatic rudder trim has to do with this discussion.
