I use this function for the elevator and aileron in the Airbus. The responses to the sidestick are linear, but not as strong as with the specified gradient. If the slope were less strong, the response of the control surfaces would be less strong with a given sidestick deflection. This would be particularly important during flare in order to be able to do a perfect landing.

But doesn't this cut off the extreme edges of deflection?

So here is a brief description of the options that you have in AAO to adjust the controller response.

 

Linear (=no curve)
1. Adjust the margins by pulling in the blue triangles or using the RAW-dialog
 This will make the linear response "steeper". For a given position of your physical lever there is more deflection on the surfaces compared to the default

2. Adjust Axis Min and Axis Max - making them smaller (Add/Edit Axis dialog)
 This will flatten the linear response. For a given position of your physical lever you get less deflection on the surfaces compared to the default

3. Adjust the Center Point by moving the red triangle or using the RAW dialog
 This will move the linear "line" left or right, off the center.

4. Add a deadzone around the center in linear or non-linear mode
 one will "cut" the deadzone from the full travel, the other will "calculate around it"

5. Add detents to the axis
  Detents can be freeley positioned and sized. The app will send the same output value as long as the input value is inside that detent.
 
Curve:
all of the above combined with a simple S-shaped curve.

1 and 2 are probably what has been discussed here, but I can't be sure. What is bugging me about this is, that in both cases 1 and 2 you have to sacrifice either the full travel of the phyiscal device or the full deflection of the surfaces. I see no mathematical way to avoid this, and that is what I don't "get". Take the Aerosoft airbus for example, that had a control calibration routine. If my controller wouldn't go full travel, I couldn't pass that test. So I would probably create a second control layer where the joystick is configured as default, so I can switch between adjusted controls and default controls on the fly.

In reality these options were made to counter deficiencies on the input devices (faulty, noisy, jumpy potentiometers, mechanical shortcomings etc.). Lower spec gaming hardware is less than perfect, and I have quite a few where the physical response was anything but linear.

Thank you, that's the solution. In my case with the Thrustmaster Airbus Stick and the FlyByWire A320 Neo or the Fenix A320 I never need the full rudder deflection. But a slightly more sensitive conversion of the inputs (= shallower gradient) is very helpful
