Plane experts query how collision happened in ‘most controlled airspace’

Listening: The audio of the air traffic controller seems to indicate the helicopter to avoid the aircraft

The aviation industry is trying to understand how the fatal hollow collision between the passenger aircraft and the military helicopter happened in the “most controllable place in the world’s most controlled airspace in the world”.

A three crew of the US Army Black Hawk helicopter collided with a jet aircraft of an American airline, carrying a 64 -second aircraft, and then passenger plane will land at Washington National Airport.

Two planes were sent to the cold Potoma River on Wednesday night.

The exact cause of the crash is still unknown.

According to data from the National Transport Safety Commission (NTSB), officials will release preliminary reports within 30 days, which is leading the investigation.

According to CBS of the Broadcasting Corporation’s American news partner, staff can restore the flight data recorder (called black box) from the wreckage of Thursday. These devices can help investigators point out the cause of collapse.

Restriction

The airspace of the Columbia SAR is severely restricted to protect the national security and accommodate the core aspects of the US government.

Prevent commercial aircraft from flying over the Pentagon, White House and other historical landmarks.

However, many air transportation in the area, aviation lawyer Jim Brachle handled many litigation affairs related to jets and Reagan Airport, he told Broadcasting Corporation.

There are commercial transportation, as well as private aviation and helicopters flying in the city, often carrying senior officials and politicians between sensitive places.

He said: “You have these very narrow paths, and there are many congested and extra planes, so you put many aircraft in a very narrow space.”

The Federal Aviation Administration (FAA) and NTSB’s former aircraft accident investigator Jeff Guzzetti told BBC NewShour that helicopter seemed to communicate with the control tower before the accident. He said the air traffic controller pointed out the flight from US Airlines to helicopters.

“The helicopter pilot said that he saw the plane and would separate it visually-then the accident occurred, and the accident occurred soon-therefore, there are many questions about the helicopter pilots?” Mr. Yoshidi said.

Helicopter area

Todd Inman, part of the NTSB board of directors, said that DC is also a “unique environment” because they allow them to fly.

He said: “If you look at DC, you will see that many helicopters enter the area, so there is a very clear system in this regard.”

Mr. Yingman could not provide any details about the helicopter helicopter before the flight collision between the helicopter and the US airline.

Brachle handled many litigation affairs related to jets and Reagan Airport. He told BBC that the remaining problems were the ultimate result of the two aircraft in the same aim.

He said: “The real unique place in Reagan is on the river. There is also a helicopter route that pass through that final method, which is 200 feet or below.”

Brache said the method of helicopter lines with aircraft.

He said: “You may put two different planes in a small space without any separation.” “If you get a bit too low, it is a bit too high, then you will eventually be in the same Location.”

“Contact” of the aviation system

Aviation Advisor Philip Butterworth-Hayes said the incident occurred in the “connection between different aviation systems” including civilians and military systems and the unique procedures for airports.

He added: “The boundaries of your three or four aviation systems here-on the boundary where most accidents often occur.”

But John Strickland, a British aviation expert, said that the number of commercial air traffic in the region cannot fully explain why fatal collisions occur.

He pointed out that in addition to the Washington citizens near the city center, there are also international portals, Washington Dulles, and Baltimore Airport.

“You must manage traffic flow to be separated. Just as we have in London, you must manage traffic flow between Henhero Airport, Stanst, Gatewick and London City.

“Therefore, DC is no different from London or New York in this sense … This is not completely rare.”

Mr. Butterworth -Hayes continued: “This is the most controllable airspace in the world. You have the US government and civilian system -Ronald Reagan Airport and even owned by the government. This is one of the very similar people.

“Considering the safety and the number of civilian security organizations in the region, this is indeed the safest in the world-it should be the safest aim of the world.”

The last fatal collapse of a commercial aircraft in the United States was in February 2009. Officials and experts emphasize that this incident is very rare due to the strict security restrictions on all types of flights.

The video partner of the United Kingdom (BBC) American news partner Columbia Broadcasting Corporation (CBS News) from the air traffic control source showed that the two aircraft seemed to involve the collision accident. Essence

The audio proposed by BBC News seems to confirm that the helicopter is in contact with the air traffic control on the airport ground.

The helicopter was asked if he “saw” the passenger plane and “in”. In subsequent audio, the controller seemed to realize that it had collided, and you could hear other planes instructed to the airport nearby.

Mr. Butterworth-Hayes said that such air collisions require many problems.

He said that in order to fly in the field of civilians, military helicopters need to install a responseer to remind the plane of the surrounding aircraft.

He said that this means that both planes should be able to meet with each other. In addition, the instructions of air traffic control and aircraft protection safety devices will have instructions that run separately.

“In this case, you have these two different systems, and both should be able to separate these aircraft.”

The Black Eagle helicopter is part of the 12th Air Camp B. It left Virginia’s military base Belvoir Castle and participated in training activities.

Helicopter crew “quite experience”

US Secretary of Defense Pete Hegseth said the crew of the helicopter “quite experience” and participated in the annual night flight training.

Cedric Leighton talked to the US CNN (CNN)-Retired U.S. Air Force said it was normal Musical instrument required for flying in darkness.

He said that a duty of the department was transporting senior personnel around the capital-although it was a training flight when the crash accident occurred, no one boarded the plane while crash.

He added that the pilot of the unit is expected to be proficient in the busy leader of DC and “to avoid training in such incidents.”

Butterworth-Hayes said that only experienced pilots can train in such a busy lead.

“Whether training for new systems or equipment, we all need to know which systems the pilots have opened in the helicopter, whether they have all the safety systems on the boat, or is they trying to try new programs or new routes.”
