How do I adjust control sensitivity in Prepar3D?
To adjust control sensitivity in Prepar3D, open Controls from the Options or Settings menu, select the correct joystick, yoke or pedals, then open its calibration settings. Change each axis’s Sensitivity and Null Zone sliders, apply the changes, and test small inputs. Use only enough null zone to remove centre jitter.
How do I change Prepar3D joystick sensitivity?
Prepar3D calibrates analogue axes separately for each selected controller. Menu wording varies slightly between releases, but the controls and calibration pages contain the same essential settings.
- Open the Controls settings. Find Controls under the simulator’s Options or Settings menu and confirm that controllers are enabled.
- Select the correct device. Choose your joystick, yoke, throttle or pedals from the controller selector. Settings changed for one device will not correct an axis assigned to another.
- Open the calibration page. If a mode selector is shown, choose normal flight rather than Slew. Slew controls are configured separately.
- Select one axis. Highlight Aileron Axis, Elevator Axis, Rudder Axis, Throttle Axis or the relevant brake axis, then adjust its Sensitivity and Null Zone sliders.
- Apply and test. Make a small change, select Apply or OK, and check the aircraft before adjusting another axis. This makes it clear which change improved or worsened the response.
If the required axis is missing, assign it on the axis-assignment page first. Sensitivity cannot correct an axis that is unassigned, reversed or mapped to the wrong control event.
What sensitivity and null-zone settings should I use?
Start with high sensitivity and the smallest null zone your hardware permits, then adjust each axis according to its actual behaviour. This gives a clean controller its full, direct range without discarding movement around the centre.
| Control behaviour | Adjustment | Reason |
|---|---|---|
| Stable and accurate around centre | Keep sensitivity high and null zone minimal | Preserves a direct response and usable axis travel |
| Surfaces flicker or the aircraft wanders hands-off | Increase null zone one small step at a time | Ignores electrical noise close to the centred position |
| Small movements produce abrupt pitch, roll or yaw | Reduce sensitivity gradually | Softens the overall response, though excessive reduction can make the axis feel weak |
| Controls feel sluggish or fail to reach expected travel | Raise sensitivity and check hardware calibration | A low setting or incomplete raw axis range may be limiting the command |
| There is a noticeable delay before the aircraft responds | Reduce the null zone | An oversized dead zone discards useful movement |
Do not copy one setting across every axis. Rudder pedals may need a modest null zone while a clean yoke needs almost none. Non-centring throttle levers should normally use a minimal null zone; idle or full-power problems are better corrected through calibration.
Prepar3D’s sensitivity control is a broad adjustment rather than a finely shaped response curve. If your controller software or aircraft supplies its own curve settings, shape the response in one place only. Stacking two curves can create an unexpectedly flat centre followed by a sudden increase in control input.
Why are my Prepar3D controls still twitchy?
Twitchiness that remains after calibration usually comes from duplicate assignments, noisy hardware or aircraft-specific input processing rather than the sensitivity slider itself.
- Duplicate axes: Prepar3D may create default assignments on several connected devices. Delete extra aileron, elevator, rudder and throttle assignments so only the intended device controls each axis. A mistake we see constantly is a joystick twist grip fighting dedicated rudder pedals.
- Noisy raw input: If the axis jumps before Prepar3D is running, a large simulator null zone merely hides the fault. Use our Windows joystick test and calibration checks to confirm that the device centres cleanly and reaches both ends of its travel.
- Reversed or incorrect mapping: An axis moving backwards needs its reverse option changed. An axis assigned as a button or mapped to the wrong event must be reassigned.
- Aircraft-specific controls: Some complex aircraft process throttle or flight-control inputs themselves. If default Prepar3D aircraft behave correctly but one add-on does not, retain the working global settings and use that aircraft’s supplied calibration method.
- Autopilot or trim: An engaged autopilot, heavy mistrim or active flight-control system can make inputs appear delayed or opposed. Disconnect the automation and trim the aircraft before judging sensitivity.
For a completely new control setup, our practical controller set-up guidance covers calibration order, small dead zones and checking competing assignments.
Do sensitivity settings apply to every aircraft?
Prepar3D sensitivity normally follows the selected controller and active control profile, not an individual aircraft. The same input can still feel very different because control authority, stability, airspeed and flight-control systems vary between aircraft.
Tune the baseline with a familiar default aircraft rather than compensating globally for one unusual add-on. If your Prepar3D release supports control profiles, separate profiles are useful for devices or aircraft categories that genuinely need different response settings.
How should I test the new settings?
Test full travel on the ground, then assess small inputs in trimmed flight at a moderate airspeed with the autopilot disconnected. The aircraft should remain steady with the controller centred, respond without a dead pause, and still achieve the expected control travel near the axis endpoints.
A stable approach is particularly revealing: excessive elevator sensitivity causes over-correction in the flare, while too much null zone delays pitch and rudder inputs. Our explanation of testing control during a visual approach and landing provides a useful final check after calibration.
