Recently, the incident of China Eastern Airlines flight MU5735 can be said to affect the hearts of all Chinese people, and netizens are always concerned about the progress of the rescue work. At present, the two black boxes of the plane are being decoded, and the accident investigation team is also conducting an investigation to determine that we are waiting for the official announcement of the real cause of the crash.

The sensor that grounded a Boeing plane

Once the accident happened, there were many speculations about the reasons behind the crash, one of which was that the aircraft's sensors failed, which caused the plane to dive straight into the crash.

After the accident, the data shows that the model of China Eastern Airlines MU5735 is Boeing 737-800. I believe everyone is familiar with the "Boeing" series of aircraft, especially the Boeing 737 series. It is one of the aircraft that has suffered many aviation accidents. , Boeing 737 series airliners have more than 30 accidents.

Among them, the Boeing 737 MAX 8 was grounded by the Civil Aviation Administration of my country due to a series of accidents caused by sensor errors. Soon after, the aircraft was also grounded worldwide. The personal safety of passengers is the most important.

In 2020, the U.S. House of Representatives released an investigation report on the successive crashes of Boeing 737 MAX 8 aircraft, showing that the accident was mainly attributed to MCAS, Boeing's new maneuvering characteristics enhancement system.

The MCAS has two angle-of-attack sensors, usually mounted on the side of the aircraft near the nose. The sensor installed on the nose of the aircraft monitors the size of the angle of attack. If the sensor detects that the angle of attack is close to the stall state, MCAS will adjust the horizontal wing surface of the aircraft tail to make the aircraft "bow down" to avoid entering the stall state. However, related investigations revealed that the MCAS system failed due to faulty sensor measurements on the Boeing 737 MAX 8.modbus tcp gateway
