What is happening in the United States with control of air traffic? Here are the facts

Over the past few weeks, a number of exciting technical interruptions affecting the International Airport of Freedom International Airport, many and asked if it is safe to fly in the United States.

The airport department heading the airspace around the airport held three communication in two weeks, including 90 seconds radar and communication mixture on Friday.

On Monday, a cut was affected by a management object in Denver.

None of the events caused airplanes to collide or collapse. But no one is the seriousness of what happened or the danger of being represented.

What happened in Newark Airport

When a plane is in the duration of the road or downtime, those who control the air traffic in the tower of the airport are responsible. Because it is a tower, they can physically see the planes they control, as well as use radar and radio systems.

However, when a plane is already taken or landed at the airport, but when the last approach is still decreased, a different group of air traffic controls is responsible. They direct all aircraft near air and airports. Due to distances, these supervisors cannot see planes. In order to know where the planes are radar screens and radio communication only rely on radar screens and radio communication.

Their object is known as Tracon standing for the terminal radar approach control. Tracon was in Long Island, but last year the US Federal Aviation Administration moved to Philadelphia, because the high price staff of the living in the New York region was difficult to attract.

The information from Newark airport and nearby radar sites is sent via a telecommunications line to the Philadelphia Tacon specified in the screens of managers.

This telecommunication line is twice in the last three weeks, at a time with about 90 seconds at a time, a third, in the absence of an unknown interruption. This did not know where the plains were not where the supervisors did not.

In the airspace, dozens of aircraft in the tracon control can be many plane in similar heights. You won’t know they don’t know exactly what can cause a catastrophic collision.

There was no disaster, but the experience has traumed so much traumatic than at least five controllers who went to stress leave.

In response to the menvads, the authorities of the airport cut the number of flights in and out. Caused persistent delays and cancellations.

Was the same thing in Denver on Monday?

It was not yet clear if it was similar, but was the same.

This is an ArtCC (Air Route Traffic Management Center) is the subject of a third air traffic. The supervisors there are responsible for those who are reptiles, generally flying high altitudes and areas, but do not decline.

Denver Artcc, lost communication within 90 seconds. Similar to the Newark Tracon, the supervisors could not see the planes they were responsible for the radar screens. However, in this case, they used a spare frequency to communicate with pilots.

The FAA is exploring what happens, but it is not known whether a telecommunications line is still unsuccessful as in Newark.

What is done about it

Newark Airport is already less flights, partial communication problems are combined with employees chronically, many supervisors work a lot.

FAA, air traffic controllers have increased, and three new high bandwidth adds telecommunication ties and transfer to a more reliable fiber optic network, said he placed a temporary reserve system to Philadelphia Tracon.

The FAA, nationwide has been working for about 14,000 supervisors, but at least 3,500 people say, it is necessary to hire.

The US Transport Secretary Sean Duffy should also be spent on the upgrading to billions of dollars for about three to four years to raise air transport management systems.

Is it safe now in the United States?

Duffy says the flyers are safe and the improvements are urgently needed.

More than any other airline than any other airline said that Newark is more “completely safe” than any other airline on Monday.

But many passengers are not sure so. Some have promised to escape from Newark so far.
