Experts ask why Black Hawk helicopter may have been flying above allowed altitude before crash | Global News Avenue

Military Black Eagle helicopter Hit the passenger plane On Wednesday, it seemed to have a permitted height near Reagan National Airport, which was analyzed by Columbia Broadcasting News.

This data point is one of the key mystery caused by investigators to seek explanation The worst air disaster in the country Aviation experts said more than ten years.

“This is the question of $ 64 million to be answered,” Greg Feith, a former senior aviation security investigator of the National Transport Safety Commission, said in an interview with CBS news.

Allowed flying ceiling On the Poto Mark River near Reagan National Airport, there is 200 feet-this is a vital ceiling that can safely avoid the large amount of military helicopters, and can safely avoid stable commercial aircraft traffic and outside.

Flightradar24’s data tracking and recorded aircraft data from most of the entire United States, showing that the last estimate of the last estimate when the helicopter crashed was about 400 feet. According to data from Flightaware and Flightradar24, the height of jet aircraft is about 375 to 400 feet.

Fei Si said: “They are military pilots; they are familiar with the route.” “Why do they (more than) 150 to 200 feet higher than what they know during that day?”

Steven B.

Wallace said: “I don’t want to speculate the reason, but I can speculate the thoughts of the investigators.” “I think this is likely to be the point.”

Pete Hegseth said the investigation was checking whether the plane was at the right altitude height. NTSB investigators have not yet revealed the helicopter helicopter in the briefing and stated that their working group will evaluate “prevalence and height.”

The deviation of the Army helicopter above the flight ceiling is one of the deviations similar to several collisions involving the Reagan national helicopter.

According to the anonymous report of NASA’s aviation security report on the CBS news data team, in July 2015, an air collision between aircraft and helicopters had 400 feet. system.

The pilot’s report said that the plane “was at the close contact of another plane.”

The 2015 report said: “This happened about 400 feet away from the ground, until the pilot monitors must take control to correct it to prevent it from becoming an air collision.”

Two years ago, in May 2013, a pilot reported a helicopter problem and landed around the 33rd runway. The “floor” or the minimum height during the road is because they need to hit the runway to have the greatest distance to stop.

The pilot wrote: “When we continue to go further; the tower indicates that the helicopter is 360 for the jet aircraft in the 2 miles of the 2 miles of the runway; and report it to him in the sight.”

The report said: “Tower asked if the helicopter asked us to see. He answered ‘is’ is’; the tower tells him to keep the visual separation.” “When we start from the base to the final; What.

The pilot reports that the difficult right turns must be performed, and the method of abortion to avoid collision. The report said: “Because it is on the left side of the plane, I’m not sure how close to the helicopter; but I think it is just a few hundred feet.”

CBS NEWS’s review of NASA security data has determined at least 9 games in the airport’s air collision since 2005, including three helicopters involving helicopters.

Fei Si said that he believes that NTSB and military investigators will check the helicopter in the helicopter to check whether they fail, and check whether the pilot will hinder the pilot’s ability to keep the helicopter at 200 feet. Night -looking mirror.

He said that the recorder on the two planes would help determine what happened. The authorities reported that they had recovered from the Potomac River on Thursday.

“If they are at 200 feet, there will be no problems, because the aircraft is usually 400 to 500 feet from the ground.” “It wasn’t until the helicopter hit them, and the two RJ (regional jet aircraft) pilots knew that it was that it was What attacked them. “
