The pilots discussed alternative ways to land before the flying JEJU flying

Gigo Air Pilot 2216 referred to three different plans to land with the stricken plane in the minutes that preceded it and killed 179 people in December, according to a partial version of their communication with the air traffic monitors obtained by the New York Times.

The text shows that the pilots reported the bird’s strike and learned the May Day call when they approached the Mawan International Airport in South Korea on the morning of December 29. They said they would go to the left, then asked to move right, and intend to approach the only runway to the airport from the south. When this failed, air traffic observers asked whether they wanted to land from the opposite direction, and the pilots said yes.

Plane She fell to her stomachCross the runway and hit a tangible structure that includes navigation tools, and explodes in a deadly fiery ball. Only two people-gifan survived at the back of the plane, which is Boeing 737-800-.

The cause of the catastrophe is still being investigated, which is more destroyed by a bloody plane on the South Korean soil, and the exchange between the pilots and the control tower can be a decisive piece of the mystery. This is because it covers a period of about four minutes, as each of the aircraft registrar, known as the black boxes, stopped recording.

The version does not include any information about the status of Jet engines or its electrical supply, which are intense concentration areas for investigators. It is still unclear why black boxes appear or why the landing equipment has not been involved in the plane.

The text was read on Saturday to Relatives of the victims By a council representative investigating the accident. The official told them that reading excluded parts of the conversation to protect the privacy of the participants, according to the people who participated with them. Officials did not publicize the text publicly, and the Board of Directors did not immediately respond to a request for comment.

Multiple investigations, including a police action, are being conducted in South Korea for the cause of the accident and the factors that may have made it more common, such as the solid concrete structure at the end of the runway. American and French investigators help in an investigation.

Much of what happened in the morning of December is still a mystery.

As the plane, which took off from Bangkok, approached Mawan in southwestern South Korea, it started to go down, as it reached a height of about 700 feet before it was exposed to the problem.

It came first a warning: Air traffic monitors told the pilots to be careful because there are birds in the area. After about a minute, each of the plane’s black boxes – airline data registrar and audio recorder in the cockpit.

This interruption has complicated the investigation. But the videos filmed by the spectators, a preliminary report of the accidents issued by the Korean authorities, and now provides a pilot exchange version with the control tower some evidence.

This is what we know:

At approximately 8:58 am, the pilots reported the bird’s strike to the tower and announced their intention to rotate. My Day, My Day, said one of the pilots. “Getting.”

The authorities later found feathers and blood from the immigrant duck known as Baikal Telez in both aircraft engines. Videos of the eyewitnesses also recorded a high uproar of the right engine, which airline experts described as a compressor or air flow disorder.

After the Mayday call, the pilot control tower asked “Keep the runway address” and move to 5,000 feet. The pilots agreed.

This is the standard procedure when the plane is unable to land, according to Hyoseok Chang, Assistant Professor at the Ministry of Air Transport and Logistics at Hansu University in South Korea. In such measures, the plane climbs to a safe rise and is waiting for a contract pattern.

But seconds after the pilots agreed to this plan, before the plane reaches 5000 feet, they pressed them with the control tower. They answered that they will play the left and fall shortly after the runway 1. (This is the professional terms to approach the runway of the individual airport to the south; the runway 19 indicates approaching from the north).

Professor Zhang said the pilots may have decided to “return to the point of sticking and trying another approach to runway 1 might cause more problems with the plane.” The compressor booth, which was observed in the videos, indicates that there is a problem with at least one of the aircraft engines.

Ten seconds, the pilots stated that they were unable to land. They asked whether they could “leave his right turn and go to runway 1”, and the tower gave them permission to do so.

The text does not explain the reason for this attempt to fail. But at 9:01 am, air traffic observers asked whether the pilots wanted to approach the runway from the north. “Do you want to land on runway 19?” Control units requested.

The pilots said yes, and the tower wiped them to land.

After less than two minutes, the plane hit the airport runway without deploying the landing equipment. She slipped at the end of the runway, criticized the concrete structure and exploded in the fire.

It is not clear what air traffic monitors or pilots know about the concrete structure, which includes what is known as the tools system. Under international safety standards, such structures are supposed to be built to collapse on influence, but this was not.
