A short while ago I read a question about adjusting the sensitivity of the
nose wheel. With an ATR-42 it's impossible to turn during taxiing. I forgot
the solution for this problem. Which line do I have to change in the
aircraft.cfg ?
Advice highly appriciated.

I cut and pasted this from Dallas' previous post....hope you don't mind
Dallas.


Find the Aircraft.cfg file and open it in a text editor.

Do a search for the term: point.0

The eighth value in that string is the steering angle.

I usually count eight commas and the value to the left of the comma is the
one to modify.

Example:
point.0 = 1, 0.82, 0.00, -3.77, 1600, 0, 0.633, 40, 0.42, 4.0, 0.90, 3.0,
3.0, 0, 152, 180

The steering value above is: 40 (40°)

You'll have a value smaller than that... just increase it. 35 to 40
produces tight turns.

Hi Gregory,
At present the following Contact Points REFERENCE, not exact your text but a
look-a-like.
I think it's about the same?
How can I change Wheel Radius and/or Steer Angle, if this are the values
which are for steering purpose?

//0 Class <0=none,1=wheel, 2=scrape, 3=float>
//1 Longitudinal Position (feet)
//2 Lateral Position (feet)
//3 Vertical Position (feet)
//4 Impact Damage Threshold (Feet Per Minute)
//5 Brake Map (0=None, 1=Left, 2=Right)
//6 Wheel Radius (feet)
//7 Steer Angle (degrees)
//8 Static Compression (feet) (0 if rigid)
//9 Max/Static Compression Ratio
//10 Damping Ratio (0=Undamped, 1=Critically Damped)
//11 Extension Time (seconds)
//12 Retraction Time (seconds)
//13 Sound Type
//14 Airspeed limit for retraction (KIAS)
//15 Airspeed that gear gets damage at (KIAS)

Hi Wim,

I'm not sure I understand "too weak to hold the plane"?

But, the 8 value in that string is simply the angle that the nose wheel is
allowed to turn. If it is 10, then the nose wheel can only turn 10
degrees. If it is 60, then it can turn 60 degrees. You can use any value
up to 180 degrees.

The plane is on his wheels with his nose on the ground (or under the
surface)
Which string? Is it point.0 ? one of the values?
Thanks Dallas

your reference block is more complete.. disregard the one I posted.

>//0 Class
>
>//6 Wheel Radius (feet)
>//7 Steer Angle (degrees)

notice the reference starts with //0 .. so to change the wheel radius
edit the 7th value and for the steering angle.. edit the 8th value of
the nose gear string.

Yes, Point.0 is almost always the nose wheel in a tricycle gear

Another example below:
point.0=1, 2.14, 0.00, -4.18, 1500, 0, 0.5, 30.0,0.23, 2.5, 0.55, 0.0, 0.0,
0

Count out to the 8th comma. The value to the left of the comma is 30.0.
That gives this aircraft a steering angle of 30 degrees.
