How do I set up reverse thrust in X-Plane 12?
To set up reverse thrust in X-Plane 12, open the control settings and either bind a button or key to a reverser command, or use a throttle axis with a reverse range below idle. Jets usually use reverser commands; many turboprops use beta or reverse on the power lever.
The quickest reverse thrust setup in X-Plane 12
For most hardware, a button binding is the fastest way to get working reverse thrust.
- Open the control settings for your joystick, yoke, throttle quadrant or keyboard.
- Search the command list for
reverseso you only see thrust-reverser options. - Assign one command that matches your hardware: use a hold command for a spring-loaded button, or a toggle command for a keyboard key or maintained switch.
- Bring the throttles fully to idle before testing. Most aircraft will not enter reverse until idle, and many will ignore reverse inputs in the air.
- Test on the ground in a default jet first. If that works but one add-on aircraft does not, the problem is usually that aircraft's custom control logic, not X-Plane itself.
If your command list offers both a normal reverser command and a max-reverse command, use max reverse for a simple one-button rollout setup. Use a normal reverser command if you want to modulate reverse thrust with the throttle after deployment.
Should you use a button, a key or a reverse detent?
The best reverse thrust setup depends more on your hardware than on the aircraft. A mistake we see constantly is binding a toggle command to a spring-loaded paddle, then assuming reverse is broken when it stays armed after the press.
| Hardware | Best setup | Why |
|---|---|---|
| Momentary button or paddle | Hold reverser command | Reverse stays active only while you hold it, so it is hard to leave deployed by accident. |
| Keyboard key or maintained switch | Toggle reverser command | One press deploys reverse, another stows it. |
| Throttle quadrant with travel below idle | Axis with reverse range | Feels most realistic, but only if the aircraft supports reverse on the axis cleanly. |
| Separate levers for each engine | Per-engine reverse bindings | Best for twins and airliners where you want accurate left and right engine control. |
How do I set up a throttle detent or reverse range?
A physical detent feels best, but it only works properly when X-Plane and the aircraft both recognise a reverse range on the throttle axis.
- Calibrate the whole lever travel, including the section below idle if your hardware has it.
- Assign the correct throttle axis for the engine or engines you want to control.
- Leave a small idle margin if the lever jitters around idle. Otherwise the sim can flick between idle and reverse.
- Test whether the aircraft actually supports axis-based reverse. If moving below idle does nothing, use a button-based reverser command instead.
Some aircraft, especially complex add-ons, only recognise reverse through their own commands even if your hardware has a reverse zone. If you are splitting levers across several engines, our guide to setting up multi-engine throttle controls in X-Plane 11/12 covers the usual assignment mistakes.
Why isn't reverse thrust working?
Reverse thrust usually fails for one of a few predictable reasons.
- The aircraft has no reverse thrust. Many light piston aircraft do not, and turboprops often use beta or reverse rather than jet-style reversers.
- Your throttles are not truly at idle. A noisy axis or a badly calibrated detent can leave a tiny amount of forward thrust active.
- You are trying to use reverse before touchdown. Many aircraft inhibit reversers until weight is on the wheels.
- You bound the wrong command type. A toggle command on a momentary paddle, or a hold command on a latching switch, often feels broken even when it is working exactly as assigned.
- The add-on aircraft uses custom logic. If a default aircraft works and a specific add-on does not, look for that aircraft's own reverser or throttle commands.
- The wrong engine is mapped. On twins and airliners, it is easy to reverse only one engine or none at all if the assignments are mixed up.
How do turboprops differ?
On turboprops, what simmers call reverse thrust is usually the beta/reverse range on the power lever, not the same system used on jets.
If your turboprop feels sluggish, sits at high RPM or will not behave properly in reverse, read our explanation of beta, reverse range and slow turboprop throttle response in X-Plane 12. In many cases the fix is correct power-lever setup, not a jet-style reverser binding.
What if I only want a keyboard shortcut?
A keyboard shortcut works fine if you do not have spare buttons on your throttle or yoke.
Assign any free key to a reverser command in the keyboard controls. If you need the command names or want a quick reference for X-Plane's standard bindings, our X-Plane controls and keyboard commands reference is the quickest place to check.
