To adjust the sensitivity of your joystick, follow these steps: For example, with a large null zone, you can to move the joystick slightly before it affects the aircraft's controls in Flight Simulator. The Null zone setting refers to how much 'dead space' there is in a particular joystick axis center position. For example, with high sensitivity, the slightest movement of the joystick has a large effect on the aircraft's controls in Flight Simulator. The Sensitivity setting determines how sensitive the joystick is for a particular axis. You can adjust these sensitivities and experiment to find your optimal setting. The preset sensitivity for joysticks in Flight Simulator is in the middle of the range, as is the response rate. When you use a joystick to play Microsoft Flight Simulator, you can change the settings on the joystick to be either more or less sensitive to your movements.
