Landing and Taxi lights

The default behavior of the SIMCONNECT events for landing lights and taxi lights is very weird for the A320 as SIMCONNECT does not really account for 3 landing lights, one of them on the same switch as the taxi light and an independent RWY TURN OFF light.

These events often trigger several lights and switches together, and it is very hard to specifically map them to single button/switches.

One solution we have found to be working, is:

Landing Lights L
- Set LIGHTING_LANDING_2 to 0 (sets the switch to ON)
- Set LANDING_2_RETRACTED to 0 (extends the landing light)
- Delay of 8-10sec (to simulate the time it takes to extend the lights)
- Set CIRCUIT SWITCH ON:18 to 1 (turns on the actual light)
Landing Lights R
- Set LIGHTING_LANDING_3 to 0 (sets the switch to ON)
- Set LANDING_3_RETRACTED to 0 (extends the landing light)
- Delay of 8-10sec (to simulate the time it takes to extend the lights)
- Set CIRCUIT SWITCH ON:19 to 1 (turns on the actual light)
NOSE
- Set CIRCUIT SWITCH ON:17 (turns on TAXI lights and moves switch to TAXI)
- Set CIRCUIT SWITCH ON:20 (turns on T.O. lights and moves switch to T.O.)
- Set CIRCUIT SWITCH ON:17 CIRCUIT SWITCH ON:20 to 0 to turn off all NOSE lights and move the switch to OFF)
RWY TURN OFF
- Set CIRCUIT SWITCH ON:21 to 1 (turns on left light)
- Set CIRCUIT SWITCH ON:22 to 1 (turns on right light)

Doing it this way might break any third-party software trying to read the status of the lights through SIMCONNECT.

The below table shows ':' if a pump index has to be added. Replace with appropriate value for the corresponding pump. E.g. FUELSYSTEM_PUMP_TOGGLE:2

L1=2, L2=5, C1=9, C2=10, R1=3, R2=6

Please note that FUELSYSTEM_PUMP_TOGGLE 1 and 4 for the center tank pump switches got replaced with FUELSYSTEM_VALVE_TOGGLE 9 and 10, due to the NEO having jet pumps instead of conventional pumps, which was corrected in a recent update.

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

Pushback API Example
