Can anybody give a layman explanation for how curves work?

[Dave_s]

Have been fiddling with the curves in the axis calibration but to be honest I have no idea what it does or the best way to use it. I have checked the manual but other than telling me it is for adjusting my joystick settings I am none the wiser.

 

Anyone got a simple explanation for a simple kind of guy :thumbup:

 

Cheers

Curve describes how your input is transformed before game interprets it.

 

Linear response means that curve is line and response is 1:1 in all range. For example: you move stick 10% from center, game sees 10%; you move 20%, game sees 20% and so on.

 

If response is not linear (curve is used), then inputs are transformed and response isn't 1:1 in all or just part of range. For example: you move stick 10% from center, game sees 5%; you move 20%, game sees 15% and so on. If you plot your input on x axis, and plot what game sees on y axis, you will get the curve. Altering it, you will change what the game sees.

 

People usually use them to make controls less sensitive at center for easier aiming and etc. I personally don't use them.

As a further note, you perform these changes within DCS and/or FC2 through opening the options screen, selecting Axis Commands for the relevant aircraft, select the axis and click "axis tune".

Aside from the AFM's (Ka-50, Su-25T) a curve of 30-50% is most commonly recommended by most pilots for your joy-y and joy-x. This flattens the curve near center and makes it steeper near the edges of the pull (in other words, more precise near the middle and more aggressive near the full deflection area). The most critical spot is the "elbow" on the curve, where it changes from flat to steep. Too much one way or the other will be difficult to fly.
