UK Air Traffic Control glitches
From
http://www.forbes.com/business/newsw...tr1393847.html or http://tinyurl.com/2v49t "Air control outage adds to UK transport woes Reuters, 06.03.04, 8:10 AM ET By Jeremy Lovell LONDON, June 3 (Reuters) - A computer failure that briefly grounded all aircraft in Britain at the peak morning time caused airport chaos on Thursday and raised further questions about the state of the country's transport infrastructure. ..." What I found interesting was this: "... it was a link between an old control centre at West Drayton in Middlesex and a new one at Swanwick in Hampshire that opened in 2002 -- six years behind schedule and 230 million pounds ($421 million) over budget. Just months after the 600-million-pound centre at Swanwick went operational, there were reports that controllers were being plagued by 'ghost' data on their screens making it hard to identify real aircraft. " They went $421 million OVER budget! What the heck is wrong here? Why are ATC systems so expensive? And with the kinds of computation and radar capabilities we have now, why is it still so difficult to run a system efficiently? Well over a billion dollars just to display blips on a screen so a human can keep them separated? And even with a billion dollar system there are outages and glitches like this! I know I'm simplifying things here, so could someone that knows about the nuances of ATC fill me in? In a related vain, as long as we have an expert on the line, where do you think ATC is going in the future? How much automation is reasonable/practical? Are any of the new technologies available or soon to be available (GPS, ADS-B, TIS-B, etc.) as game changing as I think they will be? What is holding back progress? Enquiring minds want to know. -Aviv Hod |
