Last Saturday, the Orly airport in Paris was forced to ground all flights due to a computer glitch and not just any glitch, but one caused by a system running Windows 3.1 – Yes, the early 1990s operation system.
This glitch was brought to light by French satirical weekly, Le Canard Enchaîné, which reported that the error that cause the shutdown was traced back to a system called DECOR. DECOR is used to communicate Runway Visual Range to pilots during takeoff and landings, which during adverse weather conditions such as the fog at the time, is almost invaluable. Unfortunately, this critical system runs on the once popular Windows operating system from 1992.
The use of a 20-year-old system to run a critical system is just the tip of the iceberg, which was revealed by Alexandre Fiacre, the secretary general of France’s UNSA-IESSA air traffic controller union. “The tools used by Aéroports de Paris controllers run on four different operating systems, that are all between 10 and 20 years old,” he said “Some of ADP’s machines run on UNIX [an operating system favored by universities and start-ups in the ’80s], but also Windows XP”. Frighteningly, ADP is the company responsible for running two of France’s busiest airports: Orly and Charles de Gaulle.
His further statements only serve to make me think flying to France may not be the safest prospect, stating that the dated systems are ill maintained, a lack of staff qualified to maintain them and that they are forced to resort to scouring eBay for the parts they need to keep the systems running. And even the promises made by France’s transport minister that the systems would be replaced by 2017 are doubted by Fiacre, believing 2019 would be the earliest it could be done.
I for one, worry about the safety and security of systems that are used in critical systems, when they continue to be run on poorly maintained, dated systems. I might even be thinking twice about using air travel…
