B-52 Re-engining?

So one doesn't use rudder when doing a manual turn as one does on every
other aircraft made?

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

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.

automatic rudder trim in the 747-400 except during autoland operations

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

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

What??? It coordinates turns? Not in my Boeing shop. In lab testing and
flight testing, both analog and digital yaw dampers, we never found it to
"coordinate turns". My Boeing documentation shows this not to be true.

"Fugoids"??? What, another Traverism? Me thinks its spelled
Phugoid.......with a "PH". Go ahead....look it up. My 5th graders' dictionary
has it. Yours might.

Where is your shop Lenoch?

Weiss found what I wrote to be correct, perhaps you could explain the
difference between your running your mouth and his actually looking up the
facts.

Boeing -Renton, of course.......1977 to 1984.(one of them, at least).
Were you there?
What psuedo facts do you know?
If you would get your little prick out of your mouth sometime, you would know
some facts, you little prevert.
You are the one that jams this board with you mouth and your other end running
off all time. I hope you read each word here, because you know its is true.
Why don't you and Weiss hold hands together and just PLONK anyone that doesn't
worship you. You've Plonk'd me before, so do now again.......make it easier on
both of us. After all, what I say doesn't matter to you.......isn't that
right?
VL
PS: Weiss has the wrong facts also. Just check anyone of the avionics
manufacturing shops......start at Cedar Rapids, if that's a clue that will
help.

I am in California, but spent '97 in the Everett shop.

Come on now Lenoch, you are the one posting ignorance.

What did you do in Renton?

If you would get your little prick out of your mouth sometime, you would

My goodness, are you a latent homosexual as well Lenoch?

Right now we are discussing an issue for which I am correct and it is you
that has taken leave of his senses, Lenoch.

I don't know about Weiss for sure, but I like the beaver. Like a sweet
sweet oyster .

That is quite a tantrum Lenoch, do you have trouble retaining employment?

I am in responsibe charge of engineering for an avionics manufacturer. We
supply aircraft interface to Collins, Honeywell, BAE Systems et al., as well
as every western comercial airframe manufacturer. Now we are begginning an
MI rotary wing project for some of the new NATO members, so we will be in
the East as well. Oops, I forgot, we already have repeaters going on the
new Chinese passenger airplane as well soon.

Only retaining you.

"T he phugoid mode is the simplest oscillatory mode in aircraft dynamics. The
only governing force is gravity, and energy is conserved, as there are no
dissipative mechanisms. The airplane can only trade kinetic energy for
potential and vice-versa. For a stationary observer the aircraft trajectory
looks like a sine wave, while for an observer moving with the 'average' speed
of the aircraft it looks like an ellipse. These are shown by the following
applet: "

Then they show graphics. I bet Tarver will say he doesn't have to look there
since he is smarter, that I am "trolling" and he will now call me names.

For the rest of you it is a rather nice visualization.
