A32NX Known Issues
The following list of issues are commonly reported on our Discord support channel. Please check these before reporting any other issue on Discord.
Invisible Aircraft
Invisible Aircraft
Affected versions: Stable, Development
Description
The aircraft can be selected but is invisible in the Hangar and after starting the flight.
Possible Solution or Workaround
Infinite Loading Times
Infinite Loading Times
Affected versions: Stable, Development
Description
While loading into a flight, the loading never stops and the flight never starts.
Possible Solution or Workaround
Try these solutions:
- Wait at least 20 - 30 min, as loading after an aircraft update can take a very long time because the sim compiles the so-called wasm files
- Remove Old Marketplace Installation
- Clean Install
- Use the Latest Version of MS Flight Simulator
- Enable Windows UTF-8 Support
- Test With Only the A32NX Add-on in Community

Unexpected Engines Shut Down
Unexpected Engines Shut Down
Affected versions: Stable, Development
Description
The aircraft is unexpectedly shutting down the engines. This is usually caused by either a conflicting controller mapping triggering the engine shutdown, e.g., when using the keyboard or controller when retracting the gear or flaps.
Another common cause is users forgetting to fuel the aircraft.
- Remove the conflicting mapping (e.g. "Auto Start Engine" or similar)
- Follow the correct fueling procedure for the A32NX: Fuel and Weight
MSFS Freezes After 'Ready To Fly'
MSFS Freezes After 'Ready To Fly'
Affected versions: Stable, Development
Description
If your username on your Windows machine (not Xbox gamertag) contains any Unicode characters, it may cause MSFS to freeze after selecting Ready to Fly
.
Sample characters (not all-inclusive): ë or õ
Root Cause
Unicode Characters in Windows Username.
Under Investigation.
Possible Solution or Workaround
Change your windows username and remove any Unicode characters present. Guide Here

MSFS Performance Degradation In-Flight
MSFS Performance Degradation In-Flight
Affected versions: Stable, Development
Description
Reports in the MSFS forums detail issues impacting FPS performance in the sim. Notably, this occurs during flights that are longer than 2 hours but is not contained to this metric. You may see your normal FPS drop to < 10 FPS as a result of this issue.
Additional Information
Follow the MSFS Forums Discussion - here.
CPDLC with Hoppie on IVAO
CPDLC with Hoppie on IVAO
Affected versions: Development
Description
The answer-transmission of ATC instructions cannot be sent and the DCDU shows "SYSTEM BUSY" or does not send the message. It is not possible to send answers, close or delete ATC instructions.
Root Cause
The IVAO ATC software Aurora sends wrong message IDs in instructions. In the message handling of the A32NX, this causes the wrong interpretation and association of messages.
Possible Solution or Workaround
Do not use CPDLC on IVAO.
Additional Information
We are working with IVAO on a bugfix.
Fuel Prediction Too Low
Fuel Prediction Too Low
Affected versions: Development
Description
Fuel prediction on the MCDU may not calculate enough fuel for the duration of your flight.
Root Cause
We are working on more realistic simulation of various involved systems, e.g., engines. The fuel predication will be inaccurate until we have updated the fuel planning feature on the MCDU. Under Investigation
Possible Solution or Workaround
When using the MCDU fuel planning feature, take more fuel than what is calculated for you - especially for longer flights.
Autopilot: Unwanted Disconnection
Autopilot: Unwanted Disconnection
*Affected versions: Stable, Development
Description
There are several common reasons for an autopilot disconnection, most of them are typically caused by user/pilot error.
One common cause is input from controllers. Make sure your controllers are working correctly and do not send unwanted input. Use the MSFS deadzone controller settings to prevent unwanted input.
Another common cause is the A320 protections for High Speed, High Angle of Attack incl. Alpha Floor. See our dedicated documentation for the A320 protections: A320 Protection Documentation
ADIRS Not Aligned When Starting at Runway or in the Air
ADIRS Not Aligned When Starting at Runway or in the Air
Affected versions: Development
Description
ADIRS may not be aligned when spawning anywhere except cold & dark at a gate (intermittent issue)
Root Cause
Initialization timing issue of MSFS.
Possible Solution or Workaround
Workaround: Restart the flight
Unexpected Out of Fuel - No Fuel Transfer From Outer Tanks
Unexpected Out of Fuel - No Fuel Transfer From Outer Tanks
Affected versions: Stable, Development
Description
Occasionally, the sim will "miss" the trigger point being reached for outer tank fuel transfer to initialize. This may happen if the sim is "busy" working on something else OR the initial FOB at the start of the flight is below the trigger point.
Root Cause
Intermittent Issue / Under Investigation
Possible Solution or Workaround
Add enough fuel to get past the trigger point of 239 gallons before departing.
Use the flyPad fuel page to add fuel to the aircraft: Fuel Page
TCA Throttle Autobrake Disengages While Looking Around
TCA Throttle Autobrake Disengages While Looking Around
Affected versions: Stable, Development
Description
MSFS blocks all other inputs when using freelook with the mouse button pressed. The TCA knob for Autobrake setting will be lost if this block lasts longer than 1.5sec.
Root Cause
See the root cause here: Controls Freeze up While Looking Around
Possible Solution or Workaround
Do not look around the cockpit for > 1.5 s
Can't Start Engines When Using TCA Throttle
Can't Start Engines When Using TCA Throttle

Ice Building Up on Cockpit Windows
Ice Building Up on Cockpit Windows
Affected versions: Stable, Development
Description
Icing occurs (windshield, engines, wings) although Anti-Ice is turned on.
Root Cause
There is actually no anti-ice capability in MSFS, and Asobo currently has no plans to add it in the near future.
The anti-ice systems therefore work as deice systems (after the fact) rather than anti-ice systems (preventive).
Possible Solution or Workaround
No workaround, but flights should not be impacted too much by this.
Additional Information
The consequence of this MSFS behavior is that the auto-probe/windshield heat will not always prevent ice from forming on the windshield or the pitot probe. Although the ice should melt fairly quickly (and no need to switch from auto to on), the windshield can still freeze over, and you can lose airspeed information upon first entering icing conditions if they are severe enough.
The same goes for wing and engine anti-ice - turning them on before ice actually forms may not prevent ice from forming there, but it should melt fairly quickly.
Refueling/Boarding Buttons Missing/Disabled on EFB Fuel/Payload Page
Refueling/Boarding Buttons Missing/Disabled on the EFB Fuel/Payload Page
Affected versions: Stable, Development
Description
You may find the 'play' button (that is used to initialise the refueling process) or the 'boarding' button (used to initiate boarding of passengers) is missing or disabled on the 'Fuel' or 'Payload' page of the EFB (flyPad). This occurs when GSX Synchronization is enabled.
GSX is a third-party software developed and sold by FSDreamteam, which you can purchase and install to enhance ground operations at airports.
Possible Solution or Workaround
-
If you are not using GSX, then you will need to disable both options on the GSX Synchronization page on the EFB, under Settings -> 3rd Party Options.
-
If you do use GSX, then much of the boarding and refueling process is completed through GSX itself, while also still requiring some interaction with the A32NX EFB. This is explained in detail in our GSX Integration Guide.
Pop-out Feature Not Working
Pop-out Feature Not Working
Affected versions: Stable, Development
Description
The MSFS pop-out feature is not working for certain screens in the A32NX flight deck.
While this is an MSFS issue, it can cause problems if you regularly enjoy popping out various screens for use with external hardware or another monitor.
Root Cause
MSFS off-screen pop-out issue when your monitor setup may have changed between Sim Updates. This data is reportedly stored locally and in the cloud.
Possible Solution or Workaround
Please note that you should first check the following before trying any workarounds.
- You can see the magnifying glass when attempting to pop out the panel.
You can try using the MSFS Pop Out Panel Manager application to restore the position if you suspect the pop-out is off-screen.
Download MSFS Pop Out Panel Manager

Rudder or Toe Brake Operation Issues
Rudder or Toe Brake Operation Issues
Affected versions: Stable, Development
Description
Experience problems like brakes getting stuck while taxiing or twitching rudders, or taxiing is erratic.
Root Cause
- MSFS Assistance settings (esp. AUTO_RUDDER) are activated. These need to be deactivated for the A32NX.
- Rudder setup is not correct.
Possible Solution or Workaround
- Deactivate MSFS Assistance Features
- Rudder Settings: See the correct settings for rudder using the T.Flight Rudder Pedals as an example: T.Flight Rudder Pedals Settings
Ctrl+E - Engine Start Unsupported
Ctrl+E - Engine Start Unsupported
Affected versions: Stable, Development
Description
The auto-start shortcut via Ctrl+E will not work.
Currently, you need at least the APU Avail and APU Bleeds to be switched on, as well as the fuel pumps to be on for a normal engine start. (Crossbleed starts will be implemented at a later time).
Root Cause
Our custom systems and realistic simulation of onboard systems requires the proper engine start procedure for the A320neo.
Possible Solution or Workaround
We highly suggest learning how to start the engines manually by reading our beginner guide. Beginner Guide - Engine Start Section.
flyPad EFB Missing in Cockpit
flyPad EFB Missing in Cockpit
Affected versions: Stable, Development
Description
No EFB (flyPad) visible in the cockpit.
Root Cause
Default Asobo A320 aircraft selected instead of the FlyByWire A32NX.
Possible Solution or Workaround
Select the FlyByWire Simulations A320neo (LEAP) in the aircraft selector instead of the Asobo one.
Incompatible Keyboard Mapping for Pause Function
Incompatible Keyboard Mapping for Pause Function
Affected versions: Stable, Development
Description
If the Pause
function is mapped to any key other than Esc this other key will trigger Pause
when typing it into input fields of the EFB or the MCDU when using the keyboard input mode.
Root Cause
This is an MSFS limitation for Coherent driven JavaScript instruments.
Possible Solution or Workaround
Make sure that the Pause
function is only mapped to the Esc key and not to any other keys.

Lights Addons
Lights Addons
Affected versions: Stable, Development
Description
If you are experiencing issues with the lights in the cockpit we have found some addons create breaking conflicts with the A32NX.
You may experience various cockpit lights to not illuminate the cockpit appropriately or refuse to turn on at all.
Note: This issue is separate from the UTF8 issues and strictly affects lighting only.
We have identified the following addon to be the main offender:
New Light (enhancement taxi, landing light and other extrior light) | by nicottine
Please be aware there may be other lights addons that may also cause this issue.
Root Cause
It isn't currently possible to seamlessly modify lights on planes via mods. Creators would instead have to replace the whole airplane systems definition - which breaks everything when we update it ourselves.
Possible Solution or Workaround
- Uninstall the mod
- Use an add-on linker to ensure the mod is only installed when you plan to use it.
