Colorado air traffic controllers lost contact with certain planes on Monday

In the United States, a second air traffic control installation experienced a 90-second communication failure this week after a series of disturbances raised security fears and caused the flight delays to Newark Liberty International Airport near New York.

Part of an air traffic control installation in Colorado which coordinates the flights above a large western band experienced a partial breakdown on Monday, the Federal Aviation Administration announced on Thursday. The breakdown occurred after another air traffic center in Philadelphia has experienced two radar breakdowns in the past few weeks that have left the controllers unable to communicate with planes directed to Newark Liberty International Airport, a large international center.

The colorado failure occurred around 1:50 p.m. when a pair of transmitters covering part of the airspace has fallen. Unlike their peers in Newark’s breakdown, Colorado controllers do not lose with certain pilots and were able to restore communications.

“Controllers have used another frequency to relay instructions to pilots,” said the aviation agency. “The planes remained securely separated, and there was no impact on operations. The FAA investigation. “

The two air traffic installations fulfill different functions. The installation of Philadelphia mainly guides planes that land or take off from Newark while the installation of Colorado supervises planes during their trips. The plane is generally higher in the sky, spaced further and moving at stable speeds. There are approximately two dozen of these installations nationwide, each covering more than 100,000 square miles of airspace.

The breakdown was reported earlier by the ABC Denver7 affiliate. Citing anonymous sources, the station said that nearly two dozen drivers went to Denver International Airport could not contact air traffic control for six minutes on Monday afternoon.
