It was a dangerous news when air traffic controllers directed to direct and direct aircraft that come around one of the country’s busiest airports, which repeatedly lose their radar and radio communication, but pilots, independent air security experts and federal aviation administration say other futile systems stopped the aircraft.
“I think the risk of collision or an incident increased, but not significantly due to excesses in the aviation system,” said Jeff Guzetty, “FAA and a former accident investigator of the National Transport Safety Board.
They say that there are usually different reasons in accidents like a deadly conflict between a passenger jet and army helicopters – a combination of many things that go wrong, they say.
There is a look at what happened in Newark – and how the safety nets of the people were the major pieces of protected planets.
The radar and the communication system that depends on direct aircraft inside and outside a terminal control team Newark International Airport in Philadelphia failed for a brief duration twice a year together. Another FAA facility in New York failed the main line to bear the radar signal, and the backup line did not work immediately. The system depends in the part on aging copper wires and even when there are fiber optic lines, the signal has to be slowed when it reaches the feature because FAA computers are so old that they cannot handle all data at full speed.
As a result, the controller was unable to see or communicate with aircraft coming with aircraft coming for 90 seconds on 28 April and 9 May. Their radar screen shows each flight in screen speed which suddenly turned black. His radio connections fell silent.
The main line failed for the third time on 11 May, but the backup system worked and the radar remained online. The FAA said the fourth outage knocked on radio communication for two seconds on Monday, but the radar remained online.
After the initial outage, the shorthand control center in Philadelphia already lost five to seven controllers for trauma holiday. Newarark’s terminal control team can no longer manage a whole schedule of handoff with the control tower of the airport, which has a halt and delayed in the country’s airlines. The FAA then imposed security limitations, causing more than 28 arrival and 28 departs every hour. Earlier, 38 or 39 flights usually flew and descended per hour per hour.
When air traffic controllers lose airborn aircraft ability to see or speak, they can try to do text messaging pilots through data link systems or try high -power portable radio. An emergency radio frequency can also be an option if the main communication is below. Tower controllers have high power light guns that tell the pilots to send green or red signals to them whether they are clear whether they cannot talk to them on the radio.
And the entire air traffic control system is created on the overlapping network of radar sites. So if a terminal control team loses its communication like one in Philadelphia, a controller in a radar center that usually directs aircraft at high altitude. If some other controllers in the area listen to a pilot broadcast on an emergency frequency, they can also give a message.
During these Philadelphia outage, Voice Communications first returned online, while radar took another minute to reboot, and the controller was able to hand over the planes without resorting to those some other options.
In recording on May 9, captured by www.liveatc.net, a controller can be heard saying “Fedex 1989. I’m going to exit you from here. Our scopes are black again. If you care about it, contact your airline and try to get some pressure to fix this stuff.” The pilot admitted that the controllers were wished for “good luck friends” before switching frequencies.
Acting FAA Administrator Chris Roshelora has tried to assure the public that all these backups and boundaries remain safe on the number of flights, despite these problems, which highlight how delicate and old some air traffic control systems are.
“When there are disruptions at any airport due to equipment issues or staffing, the FAA will always ensure safety by slowing down the arrival and departure of the airport and reducing the crowd,” Rochelue posted on X. “We protect the flying public because there are excesses built throughout the system during pilots, techniques and air traffic.”
Each pilot is trained on the fact that if they cannot talk to air traffic controllers, and modern passenger jets have their backup systems. Airline pilots receive all regular refresher training, which emphasizes security.
Captain Miles Morgan oversees all training for 17,000 United Airlines pilots, which is at a facility in a feature in Denver and at a feature filled with classes. He said that it is rare to lose communication, but it is something for which pilots are prepared, because most training focuses on what to do if something goes wrong.
“I’ve been flying for 30 years. I have met around 18,000 hours in joint airplanes – jets, and I have once lost communication,” Morgan said. “It was not really a deal. I just went to the emergency frequency, found a separate channel, and contacted a separate feature to come back into communication.”
In addition to many communication systems, aircraft are equipped with the technique of avoiding collision that shows pilots that all other aircraft are moving around them. Morgan said that these systems consume pilots for the trajectory of an aircraft and may recommend an action to prevent the conflict when the aircraft draws very close.
Captain Dennis Tajer, spokesperson of the Allied Pilot Association Union, said that when the pilots lose contacts with the controllers, their first action continues on their final-directed path. If the outage continues, they will broadcast their position in every other aircraft in the area – such as pilots do at small airports, who do not have control towers – because they follow their flight plans.
“This is not to reduce the severity of communication failure or radar outage, but it is to identify that we have procedures, we have trained those procedures, and we have additional equipment that can only enhance the security margin while dealing with that scenario,” said the Fresh.
