I dont know if this has been brought up before but I have found a glitch on my Airbus. I noticed it whilst flying the Paris airshow demonstration.
The rudder on my Airbus does not work once in the air!! On the ground its fine and the wheel turns as well but once up nothing, the front wheel wont turn either.
Simple I thought. I bet auto rudder has turned itself on so off I go to check. Nope its not on, hmmmm. So I jump in every other aircraft and the rudder works fine in all of them except the Airbus ???
Is there something i am missing here? i would have thought I should be able to move the rudder or in real life is the rudder setup as automatic once flying???

It's operating as designed. The FBW (Fly-By-Wire) computers are controlling
everything
automatically.
If you bank left and apply a bit of left rudder pedal, the FBW computers will automatically control both ailerons and rudder... You don't so much "fly" a FBW controlled aircraft as "tell it where to go..."

Even with fly-by-wire you still have control of the rudder. You say you can't move the rudder at all while in the air? Does it still cause the airplane to yaw, or does it not respond to inputs. If it doesn't respond, you might have a snapped rudder control cable, and you should get that checked out by a mechanic.
Otherwise, I don't know why that would happen.
P.S. The front wheel doesn't turn while you're in the air becuase it works on the same type of weight-on-wheels device that stops the gear from being retracted while they are supporting the aircraft. If it didn't work this way, whenever you tried landing with a cross-wind, you would go shooting off to one side of the runway or the other whenever the nosewheel touched down.

I have no Yaw control what so ever
n4gix I can see what you are saying, however there is no rudder movement from the rudder at all even when using the aileron!!
Also you have to have seperate control of the rudder for cross wind landings. Something is definately not right

I know that there are different levels of control available during different flight regiemes (sp)... I am not all that knowledgable about the Airbus FBW system (especially the FSX implenentation!), since I have precisely ZERO interest in tubeliners...
However, a brief squint at the Help/Learning Center might shed some light on FSX's version at least.

The rudder is mechanicly linked on an Airbus, just as on a Boeing 737. The FBW involves Spoilers, Elevators and Ailerons.
Hence the names for the 5 FBW computers on the airbus
2x ELAC (ELevator and Aileron Computer)
3x SEC (Spoiler and Elevator Computer)
The airbus does however incorporate yaw dampers which eliminates the need for turn coordination with assistance by rudder inputs.
But then again, so does the 737
If you lose all electric signals from the FBW computers to the hydraulic motors, you will use the rudder for lateral control. (but that is highly unlikely)

I just did a little test flight, and I got the same results as Gixer.
Panel says full rudder deflection:
However, no rudder deflection:
Like Gixer, I found that the rudder doesn't work while in flight, however it does work on the ground, so maybe it could have accidentally been connected to the weight-on-wheels switch for the landing gear, becuase it doesn't seem to work whenever the nosewheel has no weight on it.

Nexus, the 737's rudder works just fine
Glad it isnt just my sim though otherwise I would have to be tracking down what I had done wrong. Guess we will have to wait for an update before this issue is fixed!

Hmm...I don't understand...I could've sworn that I was able to use the rudder before...
...I completed 2 missions, Rome-Naples and the Paris flight demo, the old fashioned way (couldn't figure out how to work the autopilot...I'm guessing this is why all Airbuses fail miserably
)...
...anyways, I hope MS fixes this quick.

im glad this is happening to you guys, because in real life the plane does that, i saw it on the dicovery channel they where doing a documentory about it.
and this happen to prevent accidents from pilot mistakes,what i hate about it is that you cant do a roll with it, other than that is normal for that plane to do that. my auto pilot work well with it i like it.

But I cant see how it is normal?? If it were the case too when aileron is applied you would see the rudder move to counter act adverse yaw, but the rudder doesn't move one bit.
Sure you can still roll it as you have full aileron movement, nothing stops you from rolling the aircraft, you just cant yaw it.
As I said if you have a strong crosswind situation its going to be nigh on impossible to land without any yaw control available.
I am fully aware that FBW systems will more than likely not enable you to do things that will endanger the aircraft, however it is my belief that you should still have yaw control!!
The FBW system is there to aid things but the pilot should still be able to have yaw control of the aircraft. Think I will get googling when I get a free moment at work here to see if there is anything odd about this airbus. It just is weird why it all works when on the ground and not in the air.

You absolutely should have rudder control, FBW or not, this is just a glitch in FSX.

Fly by wire isn't an automatic pilot. All it means is that instead of hydralics or mechanical links the surfaces are controled by electrics.
True FBW can be used to limit what can be done, and it no doubt makes autopilots simpler. But it doesn't take full control of the surfaces out of the pilots hands.
