INQUIRY LOOKS AT EQUIPMENT FAILURE AFTER NEAR-MISS
AIR experts are investigating how two jets came close to collision after an equipment failure at a new £623 million air traffic control centre.
A trainee controller at the Swanwick centre in Hampshire mistakenly put the two Heathrow-bound British Airways planes - a Boeing 777 and a Boeing 737 - on a possible collision course.
But when his instructor pressed an override button which would have allowed him to warn the pilots, the device failed.
The trainee did manage to warn the Boeing 777 pilot to stay above the Boeing 737 - but the two aircraft passed close enough to each other for the incident to become an official near miss.
The incident, which occurred on Monday this week, is now being investigated by the Joint Airprox (air proximity) Board.
An aviation industry source said: "There was a system problem - no doubt about that. But there was no real risk of collision.
"Although this can be classed as a near miss, the two planes were two miles apart horizontally."
The Swanwick centre was due to open in 1996, but constant computer software problems meant it did not go operational until January this year.
Since then, there have been computer problems at both Swanwick and another air traffic control centre, at West Drayton, west London.
These problems were not the same as the one this week, but they led to controller-pilot communication problem which led to many flight cancellations and delays.
