Common Anode Wiring (Arduino)

Common Anode Wiring (Arduino)

The Arduino interface board is usually wired up with a common ground with switching perform on the outputs (+5 VDC). When working with OEM equipment this arrangement can be the opposite – korries on the panels are wired up with a common anode (+5 VDC), and switching performed with ground. With incandescent bulbs this does … Continue reading

Thales MCDU Conversion (Part 1)

Thales MCDU Conversion (Part 1)

The OEM Thales Multi-Function Control and Display Unit has now been converted with the assistance of Simulator Solutions, a local (Sydney) Australian based company.  Previously a FDS MCDU (reviewed here) was installed in the simulator – as a plug and play device this was a good substitute, but could never fully replace the keypad and … Continue reading

CRT Simulation

CRT Simulation

Modern Airbus aircraft facilitate the use of LCDs (Liquid Crystal Displays) to display aircraft navigational and system information. CRT (Cathode Ray Tube) usage has dwindled due to the superiority of LCD technology. The A320 aircraft we are simulating utilizes CRT displays, part of the EIS (Electronic Instrument System) “1”.  Creating a ‘CRT’ displays requires the … Continue reading

Safety First: Ferrules

Safety First: Ferrules

Working with electrical wires can be a nightmare. End points fray and may not have a secure fitting when inserted into a terminal. The flight simulator will be using hundreds of end point terminals from the I/O boards (Output Amplifier) and ARINC boards. There were accidental shortages to avionics in the past – this is … Continue reading

Radio Management Panel Refurbishment

Radio Management Panel Refurbishment

A 15 year old A320 RMP was recently acquired. The condition was unknown as avionics are usually only purchased ‘as removed’ (AR) – it can sometimes be a real gamble purchasing parts as you may have a broken LCD display, unusable buttons or knobs, or the whole unit may not even power on. After giving … Continue reading

Progress Report

Progress Report

When you literally have hundreds, if not thousands of parts lying around waiting to be put together (a giant jigsaw puzzle) you may tend to have multiple mini-projects developing concurrently. The following solutions are currently being developed – ASI integration with a digital servo (thank you Mick) RMP refurbishment / repair Trim Wheel software/hardware implementation … Continue reading
