Hi!I

I never use autorudder in the MSFS realism settings. My preference. If it is used you have eliminated the yaw axis from your control.I think your pilot friend should have qualified that statement by adding at normal roll rates. At normal roll rates in a commercial jet you won't get much yaw with or without yaw dampener. I have not noticed a slip/skid anomaly flying any of the PMDG aircraft. Maybe some screenies might better describe what you are seeing.

What I did was to assign the rudderaxis to one of the Levers of my Saitek Pro Flight Yoke. This Axis was configured using FSUIPC and an extensive Neutralzone was defined, just to avoid joystick noise in order to be able to see what the MD11 Yaw Dampers do, when there

Wow, you have to learn better speed control. I'm surprised you haven't encountered an accelerated stall and definitely not surprise that you are seeing a "ball width" of slip or skid in the slow regime you are putting her in. Really, in that part of the envelope I would have expected worse yawing, I think she is handling very well.

On the general subject and I don't mean to Hijack the thread, I have a little question about the rudder. Watching a air crash investigation episode on a Air Canada 767 that ran out of fuel mid flight and had to divert, the aircraft was coming in on approach too high and fast and the aircraft didn't have time to do a circle to lower it's altitude so the pilot decided to crab the plane with the rudder (to the right) and dip/bank the wind left to stay on track and create a lot of drag, loss of alt without gaining speed. Now to my point, I decided to try it out in the MD-11 and had some success, it wasn't much different to a strong crosswind approach but I couldn't get even near the crab/yaw with the rudder allowing me dip the wing as depicted in the Air Canada approach (Yes I know they're different planes). I tried at different speeds and with yaw dampener switched off and it didn't make any difference as the rudder appeared externally to be fully deflected so I guess that was max. Is the 767's maximum rudder deflection much more effective than the MD-11, isn't that extreme deflection simulated in FSX, is air crash investigations (and the first officer of the flight) exaggerating or am I just doing it wrong?

I learned that technique in a C-150.It's not just a rudder deflection Jay, it is cross-control for example hard left rudder and hard right aileron and the verticle speed should increase significantly. And it is "hard" on the controls, don't bother if you want to just 'add a little.'

Yeah, I was using the ailerons as much as possible but full/hard rudder isn't all that great (visually is quite deflected but not so much effect on the plane) because of this I was limited by how much ailerons I could use to keep on track.

Notwithstanding that the MD11 was flown at FMS SPD during the turn to final, the rudder problem can clearly be seen on departure ( picture #1 ) and on the ground ( picture #3 ) as well.Maybe somebody could post a screen in a matchable configuration / situation, with Autorudder off and without stepping into the rudder to counteract induced yaw.Thanx in advanceTE

This is how another third party add-on works on my setup:Again: Autorudder Off, no hardware rudders connected, no rudder axis defined! Most importatant: Almost no Skid / Slip tendency and especially after touchdown the aircraft didn

... since there was a noticable Rudder deflection to the left ...

You seem to able to reproduce this fairly easily. Can you post with the SD Synoptic in Config mode. This will show whether or not the aircraft believes it is getting rudder input. If it is, and you are not deliberatly supplying it, then you wil need to find where that input is coming from.

To follow.

You should go to your local airport and take an introductory ride in a trainer like a C-150 to learn about adverse yaw effects due to roll input. You'll find that there is a reason for the rudder. That last screenie you posted with an aircraft in a 20 deg bank at the low end of the speed envelope should be indicating some yaw (more than 1/2 ball) if the rudder is not deflected.In straight and level flight, pick a spot on the horizon before starting a turn to the right. Then add 30 deg bank to the right, in a real plane (unless your turn is coordinated) the point on the horizon will move slightly to the right before going left (in a right turn). That little retrograde movement is due to adverse yaw, and newbies (or fighter pilots with a billion hours) learning rudder have to spend hours in practicing level turns to learn how to coordinate the rudder with the ailerons. This is learned without any reference to the ball, that comes later. Fighter pilots don't seem to know how to use rudder either, it fun watching them at the base aero club getting their first flight in a Cessna 150 or Tomahawk.
