4.6.5 Controlling Joystick Sensitivity and Aircraft Stability<br />
To modify <strong>the</strong> joystick’s sensitivity or <strong>the</strong> stability of <strong>the</strong> aircraft, open <strong>the</strong> Nullzone tab at <strong>the</strong> top<br />
of <strong>the</strong> Joystick & Equipment screen. The three sliders in <strong>the</strong> upper right of this window control <strong>the</strong><br />
response curves for <strong>the</strong> pitch, roll, and yaw axes of <strong>the</strong> joystick.<br />
If <strong>the</strong>se sliders are set all <strong>the</strong> way to <strong>the</strong> left, <strong>the</strong> aircraft’s response to that axis’ input will be<br />
<strong>com</strong>pletely linear. This means that a 50% deflection of <strong>the</strong> joystick will deflect <strong>the</strong> airplane’s flight<br />
controls 50% of <strong>the</strong>ir travel. As <strong>the</strong>se sliders are moved to <strong>the</strong> right <strong>the</strong> response be<strong>com</strong>es curved. In<br />
this case, a deflection of <strong>the</strong> joystick from center to its halfway point may only deflect <strong>the</strong> aircraft’s<br />
controls by <strong>10</strong>%. This will dampen any aircraft movements and desensitize <strong>the</strong> user’s controls. Keep<br />
in mind, however, that in this case, <strong>the</strong> remaining 90% of <strong>the</strong> control surface deflection must take<br />
place in <strong>the</strong> last 50% of joystick movement. Thus, <strong>the</strong> controls will be dampened for <strong>the</strong> first half<br />
or so of <strong>the</strong>ir travel and <strong>the</strong>n be<strong>com</strong>e hyper-sensitive for <strong>the</strong> remainder of <strong>the</strong>ir throw. This gives<br />
<strong>the</strong> user plenty of fine-tune control near <strong>the</strong> center of <strong>the</strong> flight control envelope to hold altitude<br />
and roll precisely, but still allows for full control authority at <strong>the</strong> extremes.<br />
Try flying with <strong>the</strong> sliders in various different positions to see what setting works best.<br />
In <strong>the</strong> upper left portion of <strong>the</strong> Nullzone screen is ano<strong>the</strong>r set of sliders, labeled “stability<br />
augmentation.” These control X-<strong>Plane</strong>’s stability augmentation by damping <strong>the</strong> predicted forces<br />
acting on <strong>the</strong> aircraft’s flight control surfaces. If <strong>the</strong>se sliders are all <strong>the</strong> way to <strong>the</strong> left, <strong>the</strong>n <strong>the</strong>re<br />
is no stability augmentation of <strong>the</strong> aircraft. As <strong>the</strong> sliders are moved to <strong>the</strong> right, X-<strong>Plane</strong> will<br />
automatically add some stability augmentation to <strong>the</strong> aircraft, adding some elevator input to level
