A packaged from American Airlines and two jumbo jet aircraft military C-17 cargo averted disaster, after that they have been sent by mistake at the same altitude by the Centre of New York for control of air traffic controllers. Aircraft - the two closing 22 000 feet - came less than a mile each other horizontally and 200 feet vertically. Sounds an alarm of collision in the cockpit of American Airlines Boeing 777, warning pilots to descend. They have done, thus avoiding a possible collision.
Closing call took place at 10: 30 am January 20, approximately 80 kilometres southeast of the city of New York. The incident is now under investigation by the National Transportation Safety Board.
The American flight, with 259 passengers and crew, had taken off New York's JFK airport, bound for the Brazil. According to the NTSB, the aircraft was flying in the direction of the Southeast. The two U.S. Air Force C-17's fly to the Northwest, to McGuire Air Force Base in New Jersey.
Aviation sources tell ABC News that the controller to direct the C-17 asked the American flight handling controller to keep flying at 20,000 feet, but this controller was occupied with another jet and missed the application.
As the two aircraft headed at 22 000 feet, the controller of C - 17 realized what was going on, and again asked the other controller to prevent the American Airlines flight to climb. He then led military pilots at 22 000 feet. But the controller, hearing that the statement, think 22,000 altitude training was for the American flight - and the Boeing jet sent at 22 000 feet as well.
"The impact of a breakdown in communication can be very serious," said security consultant and former air traffic control manager Dick Marakovits. "In this circumstance, technology is reached within the system and saved the day."
The Federal Aviation Administration said controllers of the Centre of New York were required to examine procedures in the wake of miss.
Marakovits explains the works of many system together. "Each aircraft under control at the Centre of New York, receives about 8 or 10 air traffic controlled instructions by vol. times 8000 aircraft, that communications 80,0000 per day." Can there be difficulty, can there be errors of communication/misunderstandings in these 80 000 discussions? Yes it can. The system works fairly well, even if, in view of these dynamics. ?
In the incident in January, the aircraft was so close that the error has been classified by the FAA as an operational error of level "A" - the most serious kind. The FAA said the so-called operational errors, when the aircraft closer to permit, are rare. In fiscal year 2010 y were 1,889 operational errors. Four hundred forty-five of those that have been marked "A" or "B" events - the two most serious categories. The FAA just forty-four were regarded as level "A", said it is more than 133 million operations.
