Nose Wheel Appears Not To Default Straight


Kaiza

Recommended Posts

OK, had a search about, found a couple of threads, but nothing that deals with this directly, so I guess its something that probably only happens to me.

 

When my NWS is not engaged the nosewheel veers right. This makes takeoff pretty exciting and means I have been leaving it engaged for the whole takeoff role.

 

When my NWS is engaged, the nose wheel straightens. I can sit on the ground turning nose wheel steering on and off and watch my nose wheel turn and then straighten. As it is straight when NWS is engaged it would suggest that my pedal calibration is correct, so I am confused at what the problem is here?

 

Here is a pic with me on the ground and my NWS off, as u can see rudders are central.

Perhaps it is some castering logic or something? I made a track, this time it occurs to the left. It appears that it is this way when I enter the game.

When NWS is disabled it is loose so it turns to the direction the plane is going which is good for taking off. The reason for the nose wheel drifting to the left or right when NWS is off and you're standing still is just bad tire physics model when the vehicle is standing still I think. Lot's of games have that problem.

I know when NWS is disco'ed it becomes like a caster wheel, free moving. Would cross wind be the cause of the wheel to veer left or right? If no input is made from stationary to take off roll then I guess it would want to caster into wind due to the weather cock effect on the rudder surface. (Wind from right pushes on rudder surface to swing nose right into wind, therefore castering nose wheel will point into direction of swing and wind.)

 

I guess only ED could comment as to how its all actually modelled. Anyhooo... just a thought. :)

Of course, YES. You can check it at any supermarket using a cart. Push it in front of you then stop and try to turn it - take a look at the front wheels... If plane has a castering nosewheel there is a compulsory arm between axis of the nose leg (vertical) and the wheel axis. If the nose goes right the pair of forces tends to turn the wheel right. Or - the leg goes right and the point of wheel contact stands at its place. As the point is behind the leg it turns...

I haven't checked this in a while, but I do know that the wheel used to pivot to the right on me at engine start if i started the #2 engine first. Once I activated NWS, the wheel would straighten back up. I haven't flown for a couple weeks but if someone wants to check this out again feel free. It was repeatable from what I can remember but may have been fixed at some point.

Could it be you have set up L/R wheelbrake to your rudder pedals maybe?

 

I had to setup a deadzone or better said (as it's configured as a slider) modify the X/Y saturation, because once I let the pedal loose, it didn't travel fully back to it's zero position, causing one of the two brakes to remain pushed by some 2-5%. This also causes the jet to pull to the side where the brake is not fully free.

Since 1.1.0.8, I've been having this problem too.

Nosewheel defaults to right turn on entering level.

During engine start up, plane will pull and turn to the right.

Engaging and disengaging NWS straightens the wheel.

Yeah, I have just put it down to over modelled (IMO) castering.
