Find the complete list of Custom Event and Custom LVARS of the A380X:

"How to read the tables"

  • Function: The name of the switch or button on the panel.
  • API Usage: The name of the API variable or event.
  • Values: The possible values the API variable or event can have.
  • Read/Write: Whether the API variable or event can be read or written.
  • Type: The type of the API variable or event (see below).
  • Remark: Additional information about the API variable or event.

To shorten the length of the table we use the following placeholders for the API disignations:

  • {SIDE}: Replace with L for left, R for right (and sometimes C for Center).
  • {NUM}: Replace with 1 for the first, 2 for the second, 3 for the third, 4 for the fourth.

"API Var and Event Types"

Type Description
Custom LVAR are custom variables created by the FlyByWire team to control the aircraft (aka Named Vars).
MSFS VAR are variables that are part of the default MSFS SDK (aka A Vars).
SIMCONNECT VAR are variables that are part of the default MSFS SDK (aka A Vars).
MSFS EVENT are events that are part of the default MSFS SDK (aka K-Events).
SIMCONNECT EVENT are events that are part of the default MSFS SDK (aka K Events).
CUSTOM EVENT are custom events created by the FlyByWire team to control the aircraft.
H EVENT are events that are part of the default MSFS SDK (aka H Events).
INPUT EVENT are events that are part of the default MSFS SDK used mainly for cockpit interaction inputs (aka B Vars or B Events).

The below table might lag behind the current developments of the A380X. It is based on the A380X Development version, and we try to keep it updated as best as possible.

You can help us keep this up to date and improve this by reporting any errors or omissions on our - Discord in the #a380x-support channel or by creating an issue report here: Docs Issues.

The order of the panels below is roughly done after the standard cold & dark setup procedure.

The A380X Fuel Panel is split into several parts, the crossfeeds, the left and right fuel tanks, the trim tanks and the x-feeds.

The individual pumps are controlled via circuit connections. The corresponding circuit connection numbers are as follows:

Pushback API HowTo

Pushback API HowTo

Using the Pushback API is relatively easy, but you also might need some additional sim events/vars to make it work. The following step-by-step description helps you to use buttons on a controller or a Stream Deck to control the pushback.

  • Set the Pushback System to enabled ==> set L:A32NX_PUSHBACK_SYSTEM_ENABLED to 1
  • Use the sim var PUSHBACK STATE to check if the pushback tug is connected to the aircraft
    • PUSHBACK STATE == 3 ==> Pushback tug is not connected
    • PUSHBACK STATE < 3 ==> Pushback tug is connected
    • Alternatively there is also the sim var Pushback Attached which can also be used.
  • Call the Pushback Tug via the SimConnect Event K:TOGGLE_PUSHBACK
  • Wait until the Pushback Tug is connected to the aircraft
    • Should be immediately and is independent of the actual visual pushback tug being attached to the aircraft
    • This is a sim issue, as MSFS will not wait for the pushback tug model to be attached before setting the corresponding sim vars
  • Set the Pushback Movement Factor via the LVAR L:A32NX_PUSHBACK_SPD_FACTOR to the desired value
  • Set the Pushback Heading Factor via the LVAR L:A32NX_PUSHBACK_HDG_FACTOR to the desired value
  • Set the Pushback Movement Factor via the LVAR L:A32NX_PUSHBACK_SPD_FACTOR to 0 to stop the pushback tug
  • To disconnect the pushback tug, call the SimConnect Event K:TOGGLE_PUSHBACK again
