Airbus Interfacing

Interfacing an Airbus with a Flight Simulator requires some technical skill. Korry switches and push buttons can simply be interfaced to an I/O board, many which exist in the market. Most boards on the market today are only compatible with LEDs – the challenge is finding an I/O solution which can drive the current requirement for the korry bulbs.

Components such as the sidestick, rudders, spoilers and flaps panel can be wired up to a joystick board such as the Leo Bodnar BU0836A. If no transducers are present, an interface must be built to translate physical movements to an electrical signal which the computer can read.

Other genuine components such as the ECAM Control Panel, or the ATC/Transponder Panel require specific boards which can read and output ARINC429.

This page list the Airbus hardware and the current solution. It will dynamically change and will update as an interface develops.

Updated January 2018


Hardware Solution
Korry switch push buttons and annunciators


Requires an interface board (I/O) board which is compatible with Flight Simulator and the avionics software. Solution requires a board which can output 5 VDC at 0.115 A per korry bulb.

Existing boards such as those available from Flight Deck Solutions and OpenCockpit do not provide the necessary current to drive the korry bulbs. A Darlington or DMOS transistor can amplify the current, but requires additional wiring.

Native solution in development.

Flight Control Unit (FCU) and Unit


Requires ARINC429 interfacing and 28 VDC. Native solution available from Cockpit Concept. Their FCU interface board allows you to interface the hardware to Jeehell FMGS and FSX/P3D.
 Multi-Function Control and Display Unit (MCDU)


Requires ARINC 429 interfacing. Native solution in development. Requires 115 VAC for operation.
Integral Backlighting


Panel backlighting is achieved with 5 VDC. Flight Deck Solutions and Cockpit Concept have a dimming solution which allows you to connect directly to a potentiometer.
 Electronic Clock


Clock time can sync to Flight Sim time using Cockpit Concept ARINC429  Low Speed boards and requires 28 VDC.
 Radio Management Panelimg_5830 RMP requires 28 VDC and a low speed input ARINC 429 board.
 ECAM Control Panel
ECP requires either a low speed or high speed ARINC 429 transmitter board and 28 VDC for Interfacing.

Direct wiring to an interface board, bypassing ARINC 429 is also possible.

 Rudder Trim Indicator
The rudder trim indicator on the parking brake panel requires either a low speed or high speed outout ARINC 429 board and 28 VDC.
Direct canon pin output to a joystick board. 28 VDC to be supplied to the solenoid to lock the sidestick when A/P is engaged.
ATC/TCAS requires 115 VAC to operate and ARINC 429 interfacing.
Audio Control Panel
Audio Control Panel requires 28 VDC to operate and low speed ARINC 429 interfacing.
Flaps Panel
Direct canon pin output to a joystick interface board.
Direct canon pin output to a joystick interface board.
Sidestick Solenoid
28 VDC required for sidestick solenoid operations.
Triple Brake Pressure Gauge
Cockpit Concept Analogue voltage board

  1. Gooday Ben, you are doing a great job on the Airbus. I wish I had been able to buy real parts when I started back in 1999.
    Congrats on having such a nice site here, I have only just started seeing it again.

    Cheers…………..Brian W.


    • Hi Brian,

      Thanks for the kind comments. I will most likely have some more genuine (pedestal, overhead, instrument panel) parts to sell in the next month or two if you are interested.
