Interfacing Airbus OEM components required careful thought and planning. To decrease any potential difficulty with troubleshooting and maintenance, wiring was kept to the minimum with all interfacing confined within the Main Instrument Panel (MIP) and the structural foundation of the simulator.
Four power supplies are connected to the flight simulator – one dedicated 5V supply for the flight control unit interface board, one 5V supply for the backlighting and korry incandescent bulbs, one 28V for the avionics, solenoids, glareshield lighting and static inverter, and a computer PSU supplying 5V and 12V to the converted MCDUs.
Power has been distributed by using DIN terminal blocks. Backlighting the panels has been achieved by using a custom made
PCB lighting controller. Korry bulbs are switched with the Phidgets 0/16/16 boards. 28V power supply to the avionics is logic controlled with a SimStacks board. D-Sub and crimp connectors are utilised for a solder and frustration free setup. Flight controls axis and push buttons are connected directly to a Leo Bodnar or Phidgets boards. AIRINC 429 avionics are connected to high and low speed Cockpit Concept transceivers.
Airbus A320 Simulator – whats going on behind the scene?
Sidestick and tiller controls are connected to the OEM receptacle cannon plugs and wired to a Leo Bodnar joystick board and a relay (sidestick solenoid lock)
Left Main Instrument Panel – all wiring leads to the interface boards seated in the MIP; wiring has been colour coded for identification; the structure has been earthed (yellow green wire) to the power wall outlet for safety
Left glarewing – FCU interface board sits in a protected but breathable casing; below right – Phidgets 0/16/16 board controls the logic switching for the korry incandescent bulbs; below left – power supplies (5V and 28V) distributed with DIN terminals; DC circuit breakers installed to prevent overloading
Center MIP – Recess left – Phidgets 0/4/4 relay controls backlighting logic and gear solenoid; Recess right – lighting controller for the MIP and pedestal integral lighting; Above – DIN terminals distribute the glareshield lighting (28VDC); lighting controller for the FCU integral light and display lighting
Right MIP – industrial hub (10 ports) for the many devices connected to the simulator; Cockpit Concept triple gauge brake pressure interface board
Below MIP / Forward Pedestal – all wiring from the pedestal avionics and flight controls output here; Left – SimStacks controls the power and logic for the 28V avionics (RMPs, ACPs, ECAM control panel, rudder trim display) and glareshield lighting; Right – Cockpit Concept AIRINC 429 interface boards; Recess – USB joystick board and WAGO splice terminal blocks connect to backlighting (yellow wiring)
Below MIP and Pedestal – upper left – relay controls the sidestick solenoid logic (28VDC) and static inverter logic (115VAC supply); lower left – DIN terminals supplies 115VAC to avionics (DDRMI and ATC/TCAS transponder); ATC/TCAS AIRINC 429 interface board; right – computer PSU for the converted MCDUs, 28VDC power supply
