1966 onwards EDDS and FPPS Projects for the Civil Aviation Authority (CAA)
I was now working for Ian Donaldson at Great Baddow, and he put me in charge of the two major data processing and display projects which Marconi had secured from the Civil Aviation Authority (CAA). This was to install a new Flight Plan Processing System with Electronic Data Displays at West Drayton. This covered the airspace for the whole of the London TMA (Terminal Movements Area) for both civil and military flights. This was a major project, which required a highly reliable system, with triplicated hardware and a huge amount of software. At one time we had a team of over 100 programmers working on this. It was a very complex system, and for various reasons fell behind the required timescale. I was involved in regular progress meetings, which required a lot of preparation, and at one time I was working at West Drayton during the installation and commissioning phase. Although it was a highly stressful time, it was extremely good project management experience at this stage in my career. We had three growing children, and Joyce took most of the responsibility for their upbringing, as I had to work long hours. But we always made sure we had good summer holidays, including the beginning of a long love affair with Cornwall!
Coming back to the projects, we soon found it was very difficult to squeeze all the programmes needed in the Myriad computers. Without getting too technical, the computers only had 32,000 words of storage, so needed a backup disk drive, which transferred chunks of programme into a reserved area. Today's mobile phones have far more capacity! Eventually we had to separate the civil and military parts of the system, and the civil part was taken over by a new more powerful system supplied by IBM, while we were left with the military system. This was a big blow to our Company pride, but the reduced system gave excellent service through to the 1980s.
