Boeing 737 MAX aircraft 30 Ethiopian Airlines Flight 302 crash. Explained through graphics

On March 10, 2019, Ethiopian Airlines Flight 302 crashed, killing 157 passengers and crew. This was the second fatal crash of the 737 MAX aircraft.

Ethiopian flight data 302 show the pilots’ struggle

Immediately after the flight, the left corner of the attack sensor collapses, (1) cockpit warnings about unreliable air speed և altitude readings ել shake the control column with a false booth warning.

By simply avoiding the 2-minute mark, when the pilot withdraws the grandmother և disables the autopilot, the bad sensor activates the MCAS (system for adding details). (2) which drives the nose three times sharply.
The pilots then hit the circuit breakers, turning off the MCAS. But in the following minutes, the forces on the tail make it impossible to lift with the nose.
5: At the 43 mark, they reconnect the circuit breakers, providing them with electricity to move the tail, making two quick movements to clear the nose. (3) But then MCAS comes back with a sharper downward movement. “
The plane crashed to the ground 6 minutes after takeoff (4),

What is wrong? Attack sensor angle

The angle of attack sensor sends the data to the MCAS at the angle of the nose of the aircraft. The angle can stop the plane too sharply. If the sensor sends false data, MCAS will operate prematurely.

How does the angle of attack sensor work?

By disconnecting the 737 MAX automatic system, horizontal tail forces may make it difficult for pilots to rotate manually

Both Lion Air and the Ethiopian Airlines crash turned out to be the main contributing factor to MCAS.
