aircraft turning radius on ground

[Roger Wensley]

Someone wrote recently about how to adjust an aircraft's taxiing turning radius; can you please repeat it here, as I now cannot find which post it was?

//0 Class

//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)

point.0=1, 40.85, 0.00, -10.20, 1600, 0, 1.442, 55.92, 0.6, 2.5, 0.9, 4.0, 4.0, 0, 220.0, 250.0

 

The RED number is the steering angle. Adjust it higher for more angle but keep it well under 90.00.

FYI, in the real world the max nose wheel steering angle the tiller could produce in all of the big jets I flew was 60 degrees. The rudder pedal steering was limited to around 5 degrees.

Does this apply to AI aircraft as well, I often get some stuck on tight bends?

Mr Wensley,

(I been following all your scenery (but have not downloaded and installed them) for years). So now you are getting into flying I guess. Good on ya. What is needed is not an increase in steering in cnt pts section. What is needed is DIFFERENTIAL BRAKING. Check in aircraft cfg (braking) section for the line. If it is not there, add it (''differential_braking_scale= 1.000'' (without the quotes)). Now go read up on 'Using Differential Braking' : (Google or YouTube). Then go enjoy flying in the sim.

I don't think that will have an effect on the radius achievable. If I remember rightly, that setting is for the "caster angle" and the only effect it has is on the ability to self-centre after turning. For more info see:

https://en.wikipedia.org/wiki/Caster_angle

 

I don't know the true answer to the OP's question but if he is referring to a specific aircraft it is possible that the actual location of the wheels in the Contact Points section do not match the model.

I was asking the question for an AI plane that was having difficulties; so that answers one question, yes it works for AI. I am also a pilot, and originally only started to make scenery when I was learning to fly and noticed some grass fields that were not in FS9. So I am not starting to fly now, I have been doing both since 2004. Big jets are not in my log book, 3,000+ hours but all on single engine prop. And thanks to Senor Zippy for posting that again.

You're welcome, even though nobody else seemed to believe it!;)
