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

Additional Information

Also see UTF-8 Support

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

For more information on how to actually solve the issue, please reference the following GitHub issue for more information:

MSFS Popout Workaround / Pop out panel manager issue

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

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.

New Aircraft

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.

Incompatible and Problematic Add-ons/Mods

The following add-ons and mods are known to be incompatible and cause issues with the A32NX. We recommend you uninstall these before starting the sim and flying with the A32NX, especially if you experience issues with the aircraft.

Weather Radar Mod

Weather Radar Mod

Affected versions: Development

Description

Aircraft systems may no longer function appropriately when the Weather Radar Mod for FBW A320 Neo is installed.

Root Cause

This addon overwrites the entire Navigation Display.

Possible Solution or Workaround

Uninstall the mod.

Additional Information

The author of this mod specifically states that, if any issues are present with our aircraft, then this mod should be removed when flying.

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.
LVFR A321neo Compatibility Mod

3rd Party Interior Textures - Black Screens

3rd Party Interior Textures Black Screens

Affected versions: Development

Description

3rd party interior textures mods are breaking the state of our custom instruments. This is similar to the older panel.cfg livery issue that created systems conflicts.

We have identified the following texture pack to be the main offender:

Improved Textures Mod - A32NX & A320neo | by FlightFlow

Please do not install add-ons that modify files or overwrite files inside the flybywire-aircraft-a320-neo folder.

Root Cause

Conflict with our own handcrafted textures.

Possible Solution or Workaround

Remove the offending 3rd party interior texture.
