Tuning

Tuning controls how the aircraft feels. Device selection, physical limits, calibration, and button assignments belong under Hardware.

One rule keeps the interface understandable

If a setting describes the physical device, find it under Hardware. If it describes this aircraft, find it under Tuning.

Start with the essentials

Make one change at a time and test the aircraft before moving to another section.

1. Confirm the selected aircraft profile and aircraft type.
2. Set Master gain for the overall aircraft-force level within the hardware ceiling.
3. Open Aircraft setup in the section sidebar; its Aircraft tab holds Control system and Aircraft auto-select.
4. Select the Control system that matches the aircraft, including Rotorcraft (helicopter) for helicopters.
5. Adjust only the effect groups relevant to that aircraft and the problem you are trying to solve.

Sections and tabs group related controls

Use Find a control or the section sidebar to locate a setting. The profile selector, Master gain and save actions stay above the editor. Section tabs sit below the controls; the revert arrow at the top right restores the section to its loaded values.

Section switches, including Enable stick shaker, AP Follow and curve enable controls, sit in the bottom action row beside the tabs. A visible switch and the setting's value work together; check both when an effect is absent.

Only relevant sections and tabs appear. Rotorcraft (helicopter) profiles show Helicopter instead of Trim and Spring curves, and Force sensing, Pitch directions and Roll directions appear under Aircraft setup only when Force sensing input is selected. A dot marks a section or tab with unsaved changes.

Aircraft type removes irrelevant controls

Rotorcraft profiles show force trim, cyclic damping, and rotor cues. Fixed-wing profiles show their own aerodynamic, ground, trim, and stall controls instead.

Select the helicopter profile, then open Tuning → Helicopter → Force trim → Trim style. Choose the system used by the aircraft. Changing trim architecture ends the current force session; check the new mode before arming again and save the profile to keep it.

The included Guimbal Cabri G2 and VSKYLABS Cabri profiles use Electric cyclic trim. Existing saved profiles keep their settings. To update a saved Cabri profile, select Electric cyclic trim explicitly and save it.

Flight-model evidence and guarded fallbacks

Control loading derives feel airspeed from flight-model dynamic pressure in MSFS and X-Plane, so pitot/static or cockpit-indicator failures do not freeze the aerodynamic load. Indicated airspeed remains a guarded fallback when pressure evidence is unavailable.

Surface, rotor, and configuration evidence

Spoiler effects follow actual surface deployment, X-Plane 11 flap fallback is restored, and rotor vibration follows rotor speed and blade count even while windmilling. Missing or implausible optional values use explicit guarded fallbacks.

Control input and local mechanics

Control input chooses how pilot force becomes the aircraft command. Position / displacement is the normal mode. Exact AB9 hardware can use Force Sensing after guided four-direction calibration and validation. Damping, friction, inertia, and progressive stops remain aircraft-profile feel, while Hardware enforces the physical envelope and selects the exact-device renderer.

Autopilot follow

AP Follow moves linked controls toward the simulator's autopilot command. MOZA uses full authority and strength when enabled; Follow speed adjusts movement speed for trim and autopilot. Saved authority and strength remain available for other devices, within simulator and device limits. Independent sidesticks use AP neutral hold instead. Disable AP Follow and disarm if unexpected motion occurs.

Airbus-style AP neutral hold

AP neutral hold adds an Airbus-style centred sidestick while autopilot is engaged. It uses Bridge's shared force path, so it is not restricted to AB9. It is separate from moving-control AP Follow and does not implement a simulator autopilot-disconnect threshold.

For an appropriate Fly-by-wire profile, open Tuning → Autopilot → Neutral hold and enable Airbus AP neutral hold for this aircraft profile. It is off by default. When supported autopilot telemetry reports engagement, Bridge holds the sidestick near neutral. It does not move the stick to follow the flight controls or command an autopilot disconnect.

Trim compensation

Trim relief scales the aircraft profile's response to elevator trim. Manual controls can move their resting position; hydraulic and fly-by-wire controls use different behaviour. 100% means the profile's full response. Holding pressure can remain. Zero disables relief. Simulator input compensation is a separate supported capability. Leave aileron trim relief at zero for aircraft without aileron trim.

AY90 and AY210 trim compensation supports matching MSFS 2024 aircraft. X-Plane 12.2 and later uses its native trim support for compatible aircraft across supported FFB devices. Aircraft with custom control systems can behave differently.

In MSFS, the cockpit yoke animation can differ from your physical yoke while trim compensation is active. Standard simulator input cannot independently position the animation. Assess trim using pressure relief and aircraft response.

Engine rumble

Engine rumble follows engine RPM and power evidence. Idle roughness adds a coarser low-speed texture that blends away into cruise without changing steady centering or pitch and roll load.

Centre cam

Open Tuning → Forces → Centre cam to add a rounded detent around the trimmed centre on pitch and roll. These controls belong to the aircraft profile and are hidden for helicopter profiles.

Centre cam strength sets the extra resistance near the centre. Zero turns this contribution off. Begin with a small value and compare it at the same flight condition.

Centre cam width sets the travel over which the extra resistance builds. A larger width spreads the buildup over more travel and feels softer. The stability limit can widen a narrow requested transition.

Choose an editable profile, adjust strength and width with the sliders or exact percentage entry, and compare the reference curve. Reset a row or section to the loaded profile, or discard unsaved changes. Select Save to keep the settings, or Save as… to create a separate profile.

The graph shows a calculated reference response. It does not measure force at the grip. Flight conditions, Master gain and hardware limits affect the result. The cam follows the trimmed spring centre and is inactive for helicopter profiles, Force Sensing input, Disarm and paused flight. It fades out when simulator telemetry becomes stale.

Spring curves

Tuning → Spring curves holds two aircraft-profile editors. Both start off, so existing profiles keep their previous response. Pitch force buildup and Roll force buildup shape how spring resistance grows away from the trimmed centre: Linear keeps the reference spring, and Progressive starts softer. The two axes have separate curves and share one switch. Trim-dependent pitch spring changes pitch stiffness as trim changes without moving the spring centre; 100% keeps the aircraft's reference stiffness.

Drag points or enter exact values, start from a preset and watch the live response. Travel curves keep their endpoints and must rise steadily; trim curves may rise and fall. Apply curves while Disarmed, then save the profile to keep them. Discard edits restores the draft, and Undo restores the previous applied response. The graphs show the calculated reference response; they do not measure force at the grip.

For an add-on with its own trim signal, the trim curve can read one read-only X-Plane dataref or MSFS local variable (an L: name in number units) instead of ordinary elevator trim. A custom binding needs the exact aircraft title and variable name; X-Plane units label the values without converting them. Missing or stale custom data returns smoothly to the reference stiffness, and no binding writes to the simulator. Travel shaping needs native spring positioning and axis feedback; autopilot-held springs, Force Sensing and rotorcraft keep their existing response. Airspeed loading, profile strength, output ceilings and device limits still apply.

Edited values stay obvious

Dirty indicators mark unsaved edits. A row revert restores that setting; the top-right section revert restores the section. Save keeps the working profile and Save as creates a separate copy. Compare changes under repeatable flight conditions.

Save to the intended profile

Save only after confirming the correct aircraft profile is selected. Auto-select can then load the values when that aircraft connects.

To make a profile the default for the loaded aircraft, select it in Tuning, including a saved or duplicated copy, and choose Set as aircraft default in the profile toolbar. The text beside the button shows the aircraft's automatic selection. Your choice takes priority over included profiles on later flights and after a restart, and it turns on Auto-select if it was off. It leaves slider edits unsaved; use Save to keep them.
