How do I configure Microsoft Flight Simulator controls on Steam Deck?

Configure Microsoft Flight Simulator controls on Steam Deck in two layers: choose a gamepad-based Steam Input layout, then create a custom controller preset in MSFS. Keep pitch and roll analogue, use the right trackpad as a mouse, remove duplicate bindings, and tune stick or mouse sensitivity only after every input works.

This approach applies to MSFS 2020 Steam and MSFS 2024. SteamOS, Windows installed on the Deck and streamed sessions may expose different controller names, but the division of work remains the same. If the simulator is not reaching its main menu reliably, resolve the separate Steam Deck installation and compatibility issues before changing controls.

Should I configure controls in Steam Input or MSFS?

Use both: Steam Input translates the Deck hardware into gamepad, mouse and keyboard outputs, while MSFS assigns those outputs to aircraft controls.

Keep that boundary clear. Steam Input should decide that the left stick is a joystick and the right trackpad is a mouse; MSFS should decide that the joystick controls ailerons and elevators. Avoid applying response curves in both layers because doubled processing makes sensitivity faults difficult to diagnose.

How do I set up MSFS 2020 or MSFS 2024 controls on Steam Deck?

The reliable method is to start from a plain gamepad layout, create a separate in-game preset and test primary controls before adding shortcuts.

1. Open the per-game controller layout. Select Microsoft Flight Simulator in the Steam library and open its controller layout before launching it. Do not edit the general Desktop Layout by mistake.
2. Choose a gamepad template. Start with the official layout if it is suitable, or a standard template such as Gamepad with Joystick Trackpad. A heavily modified community layout can contain hidden keyboard commands, mode shifts or action layers.
3. Check the output of each physical control. Keep the left and right sticks as joystick outputs. Set the right trackpad to As Mouse, give it a primary mouse click, and leave non-essential rear-grip commands unassigned for now.
4. Launch MSFS and select the virtual controller. Open the simulator's controls settings and choose the detected gamepad. Its name may refer to an Xbox-compatible controller, Steam virtual gamepad or simply a controller.
5. Create a custom preset. Duplicate the default controller preset or create a new one, depending on the simulator version. Do not overwrite a dependable preset while experimenting.
6. Bind the flight axes first. Assign the left stick to the aileron and elevator axis commands. Change the controls filter to show all commands if searches display only existing assignments.
7. Search by input and remove conflicts. Move each stick or press each button and inspect every command attached to it. Clear unintended camera, keyboard and duplicated gamepad assignments.
8. Test in a parked aircraft. Confirm pitch, roll, rudder, brakes, throttle, view control and cockpit-pointer operation. Only then add trim, flaps, landing gear and avionics shortcuts.

For the detailed in-game process of creating profiles and finding duplicated assignments, use our MSFS control-profile and conflict-removal workflow.

What does the word Axis mean in MSFS control bindings?

In MSFS, an Axis command accepts a proportional analogue value instead of a simple on-or-off press.

Bind sticks and physical levers to commands whose names include Axis. For example, a stick assigned to an aileron axis can produce small, smooth corrections; a stick assigned to Aileron Left and Aileron Right behaves like two keyboard keys and jumps towards full deflection.

Buttons are different. Because the Deck has no dedicated throttle lever, buttons and rear grips should normally use Increase Throttle and Decrease Throttle rather than a throttle axis. The same principle applies to trim, flaps and other stepped controls.

Which Steam Deck controls should I bind in Microsoft Flight Simulator?

The most practical starting layout keeps flying and camera movement analogue while reserving the trackpads and rear grips for cockpit interaction and secondary commands.

Rear grips do not necessarily appear to MSFS as extra gamepad buttons. Mapping them to established keyboard shortcuts is usually more dependable; our MSFS 2020 keyboard-command reference provides suitable commands to assign through Steam Input.

A mistake we see constantly is mapping every available button before checking the basic axes. Build a small working layout first. Extra commands are much easier to add than an unexplained mixture of gamepad, mouse and keyboard inputs is to untangle.

How do I change mouse sensitivity on Steam Deck and SteamOS?

Change the built-in trackpad's in-game mouse sensitivity in the per-game Steam Input layout, not in the MSFS flight-axis sensitivity screen.

1. Open the MSFS controller layout from its Steam library page.
2. Edit the right trackpad behaviour and confirm that it is set to As Mouse.
3. Open that behaviour's settings using its adjacent settings or gear control. Steam's wording and icon placement can vary between interface revisions.
4. Adjust mouse sensitivity gradually. Reduce it if the pointer skips over small cockpit switches; increase it if crossing a glass-cockpit display requires repeated swipes.
5. Check trackball and acceleration options. Disable trackball-style coasting if the pointer continues moving after your thumb leaves the pad. Add smoothing or acceleration only when there is a specific problem to correct.
6. Save the change to the per-game layout and test it in a cockpit rather than judging it only in Steam's menus.

SteamOS Desktop Mode has separate system pointer settings, but those mainly govern the desktop and conventional mouse input. They may not change a right trackpad translated into a virtual mouse by the active MSFS layout.

Steam Controller trackpad sensitivity is adjusted by the same principle: edit the active per-game Steam Input behaviour for that controller. If a right stick is configured As Mouse, change its mouse-output sensitivity there as well. If mouse movement is comfortable for the pointer but too fast only while looking around, adjust mouse-look or camera sensitivity inside MSFS instead.

How do I change Steam Deck joystick sensitivity?

Adjust flight-stick sensitivity inside MSFS first and leave Steam Input's joystick response curve at its default until the aircraft responds correctly.

• Start from the default response. Confirm that the input indicator moves smoothly from centre to full travel before changing any curve.
• Add only enough dead zone to stop drift. Increase it in small steps if the aircraft rolls or pitches with the stick untouched.
• Soften the centre for finer corrections. The Deck's short stick travel can make pitch and roll feel abrupt, so flatten the response around the centre without sacrificing the outer range.
• Retain full control authority. Maximum physical stick movement should still reach maximum in-game deflection. An excessive outer dead zone or restricted output range can prevent this.
• Change one layer at a time. Do not combine an aggressive Steam Input curve with another aggressive MSFS curve.

If the same stick drifts in Steam's calibration screen and in several unrelated games, treat that as a device calibration or hardware issue rather than hiding it with a large MSFS dead zone. If it misbehaves only in Microsoft Flight Simulator, inspect the in-game binding and profile first.

What is Steam Deck mode shift, and should I use it for MSFS?

A Steam Deck mode shift makes an input perform a different action while a chosen modifier is held; an action-set layer can change several controls at once.

Mode shifts are useful when intentionally expanding a limited layout. For example, a rear grip could temporarily turn the directional pad from camera commands into autopilot shortcuts. They are poor choices for pitch, roll, rudder or brakes because accidentally holding the modifier can remove a primary flight control at the worst moment.

If controls change when a grip or trigger is held, inspect the affected input in the per-game layout and remove its mode-shift command or action-set layer. Community layouts are a common source of undocumented secondary layers. Build them only after the ordinary layout is stable.

Why does holding the Steam button move the mouse?

Holding the STEAM button while using the right trackpad or stick can invoke Steam Deck's built-in guide-button mouse chord, which is separate from the MSFS controller layout.

This is normal and can provide emergency pointer control. If the trackpad moves the cursor only while STEAM is held, however, the active MSFS layout has not configured that trackpad as a mouse. Set it to As Mouse so cockpit interaction does not depend on holding the system button.

If pressing the Steam button appears to trigger an aircraft command as well, check for an intentional mode shift, keyboard command or duplicated assignment. The button also opens Steam's interface, which can temporarily change focus; it should not be used as a normal MSFS modifier.

Why are Steam Deck controls not working in MSFS?

Most failures come from a digital output assigned to an analogue control, an inactive preset or one physical input being translated into several commands.

• MSFS does not show a controller: quit the simulator, restore a standard gamepad-based Steam Input layout, ensure Steam Input has not been disabled for the game, and relaunch. Device changes may not be detected correctly while MSFS is already running.
• The stick immediately produces full deflection: it is probably sending keyboard or directional-pad output, or it is bound to left/right commands rather than an axis. Change the Steam output to a joystick and select the MSFS command containing the word Axis.
• The aircraft and camera move together: search assignments by input and remove the unwanted camera or flight-control binding.
• Button prompts alternate between keyboard and gamepad: a Steam Input control is sending a keyboard shortcut. This is expected for mapped rear grips, but clear it if the command also fires through a gamepad binding.
• The aircraft drifts with no input: confirm the stick centres in Steam, then add a small in-game dead zone. Do not use a large dead zone to conceal a stick that drifts in every game.
• The throttle jumps between idle and full power: a button has been assigned to a throttle axis or fixed-position command. Use increase and decrease commands for digital buttons.
• The trackpad pointer is too fast only in MSFS: edit the per-game trackpad mouse sensitivity rather than SteamOS Desktop Mode pointer speed.
• The pointer moves but cannot operate knobs: add primary mouse click and mouse-wheel outputs. Some cockpit interaction modes also require click-and-drag input.
• Controls change while a rear grip is held: remove the associated mode shift or action-set layer unless the secondary layout is intentional.

Does this work with MSFS 2020 Steam and MSFS 2024?

Yes, but MSFS 2020 and MSFS 2024 should have separate Steam Input layouts and separate in-game controller presets.

MSFS 2024 uses the same underlying analogue-axis principles, but its menu organisation, command categories and preset handling differ from MSFS 2020. Our MSFS 2024 controller-profile guidance covers those simulator-specific details.

Keep one dependable general-aircraft preset for each simulator. Create variants only when an aircraft genuinely needs different controls, such as a helicopter collective, airliner throttle detents or separate engine axes.
