Satellite tracking data show the relevance of the two crashes that Boeing 737 MAX 8 has caused

Even if countries around the world decided to stop the "Boeing 737 MAX 8" flight, which crashed twice in the past five months, the Federal Aviation Administration continued to "do not have any system performance problems" But on 13 March 2019 local time suddenly ordered the airline to stop the operation of Boeing 737 MAX 8. According to the Federal Aviation Administration, data newly analyzed by Aireon , which provides aircraft tracking and monitoring systems, indicated the possibility of two incidents being related.

There is a possibility that there may be a link between the Lion Air 610 crash on October 29, 2018, and the Ethiopian Airlines 302 crash on March 10, 2019. Was pointed out immediately after the accident.

You can better understand the similarities of the two accidents by reading the following articles. Simply put, "Boeing 737 MAX 8" was used, and the accident occurred at takeoff and on the first flight of the day.

According to Federal Aviation Administration Dan Ewell, the newly discovered satellite data from the remote control flight telemetry system has been the deciding factor in stopping the operation.

Data analyzed by Aireon is from an Automatic Dependent Surveillance (ADS) system. Among ADSs, ADS-Broadcast (ADS-B) is a satellite that enables monitoring of information such as the position, altitude, and velocity of an aircraft in seconds using artificial satellites (GPS), and highly accurate position information Provide From the information collected, ground air traffic controllers can send an overall picture of what is happening around the aircraft in real time.

The ADS system was introduced to the United States in 2001 and became available globally after the Malaysian Airlines Flight 370 crash in 2014. In Europe, a number of airlines are required to install a system called "ADS-B" for ultrashort "ADS-B" after 2017, and in the United States, ADS-B is expected to be introduced in almost all aircraft by 2020 .

As the Federal Aviation Administration ordered the outage, "new information obtained from the remnants of the aircraft was a concern about the setting of the plane immediately after takeoff. A system to track the flight path of the aircraft on a satellite basis. In conjunction with the data obtained from the above, there are some similarities between ET302 and JT610, and it is better to understand the problem and to solve it by thinking that "the two accidents are the same cause". It is necessary to

However, the investigation has not yet been completed and the link between the two crash cases is not certain. People who witnessed the accident on the Ethiopian Airlines Flight 302 stated that "we saw smoke coming out of the aircraft before the accident", while the momentary 302 flight was transmitted via ADS-B of the plane It is also known that the rate of rise and fall is similar to the pattern of flight 610. It is also suggested that the Boeing 737 is related to the fact that multiple ladder problems were reported in the 1990s.

The Boeing 737 MAX 8 also reports complaints from the pilot.

Following the decision of the Federal Aviation Administration, Japan's Ministry of Land, Infrastructure, Transport and Tourism announced that it will stop Boeing 737 MAX 8 domestic flights.
