Learn FlightGear mouse yoke controls for pitch and roll, how to switch modes, fly smoothly, and fix view, autopilot or conflicting-axis issues.
To use mouse yoke controls in FlightGear, click the simulator window, then right-click until the pointer becomes a crosshair. Move left or right to roll; pull the mouse down to pitch up and push it up to pitch down. Return it towards the centre to neutralise the controls.
How do I activate mouse yoke mode?
With FlightGear's default mouse bindings, repeated right-clicks cycle through the available mouse modes until the crosshair yoke mode appears. The cursor artwork can vary slightly between builds and platforms, but the functions are normally arranged like this:
| Mouse mode | Purpose |
|---|---|
| Normal pointer | Operate cockpit switches, menus and other clickable controls |
| Crosshair | Control aileron and elevator as a mouse yoke |
| Look or pan cursor | Move the cockpit or external view |
- Focus the simulator window. Close any open dialogue or menu, then click within the 3D view.
- Cycle to the crosshair. Right-click repeatedly until FlightGear enters mouse yoke mode. With the default binding, no click-and-drag action is required.
- Apply a small input. Move left for left roll and right for right roll. Moving down acts like pulling a yoke back; moving up acts like pushing it forwards.
- Return towards neutral. Cursor displacement represents control deflection, not a command to establish a particular bank or pitch angle. Leaving it off-centre keeps an input applied.
- Leave yoke mode carefully. Centre the mouse first, then right-click through the modes until the normal pointer returns.
A common mistake we see is moving the cursor a long way and waiting for the aircraft to settle. That holds substantial aileron or elevator, so the bank or pitch keeps increasing. Use very small movements and watch the aircraft's attitude rather than chasing the horizon with large corrections.
What does the FlightGear mouse yoke control?
The mouse yoke directly controls aileron and elevator; it does not replace the throttle, rudder, brakes or trim. Those controls must come from the keyboard, clickable cockpit, or other assigned hardware.
Some aircraft or configurations can coordinate rudder with aileron automatically, but that should not be treated as nose-wheel steering. You still need rudder and brakes to remain aligned during taxi and take-off. Our reference for FlightGear's keyboard commands covers the usual fallback controls for rudder, throttle, brakes and trim.
If you have a joystick, pedals or a separate throttle connected, check that each axis has only one intended assignment. Our FlightGear control configuration steps explain how to assign and verify those inputs without duplicating the mouse-controlled axes.
How can I fly smoothly with a mouse yoke?
Smooth mouse flying depends on small control deflections, correct trim and a stable starting aircraft. A basic trainer in calm weather gives you enough time to see what each movement does; our beginner control-practice guidance explains why complex aircraft and strong winds make keyboard-and-mouse flying needlessly difficult.
- Trim instead of holding pressure: once the aircraft has the desired speed and attitude, adjust pitch trim so the mouse can return close to neutral.
- Centre before changing mode: do this before operating cockpit switches or changing the view, so you do not leave a large control input applied.
- Use rudder during take-off: the mouse yoke can keep the wings level, but it cannot by itself correct runway yaw.
- Practise at a steady speed: control response changes with airspeed, so the same cursor displacement can feel much stronger in a fast descent than during a slow climb.
Why is the FlightGear mouse yoke not working?
Most mouse-yoke problems come from selecting the wrong mouse mode, an active autopilot or another controller writing to the same axes.
- The view moves instead of the controls: you are in look mode. Right-click again until the crosshair appears.
- Right-click does nothing: dismiss open dialogues, click the 3D view to restore focus and try again. A customised mouse binding may also have replaced the default mode-cycle command.
- The crosshair appears but the aircraft ignores it: disengage the autopilot for a clean manual-control test. On system-detailed aircraft, also check control locks and any aircraft-specific hydraulic requirements.
- The aircraft fights or overrides the mouse: a joystick axis may still be active, even if the device is untouched. Remove duplicate pitch and roll assignments, calibrate the controller or disconnect it temporarily to identify the conflict.
- You cannot click cockpit switches: this is expected in yoke mode. Centre the controls, then cycle back to the normal pointer.
- The aircraft keeps pitching or rolling after a mode change: return to yoke mode, bring the pointer to neutral and correct the trim. Also check for a noisy hardware axis continuously applying input.
