"Regarding the problems with the MAX 8, we both thought it was appropriate to bring this to your attention," wrote the captain in the report. "The best guess on my part is the fluctuation in speed," which, he said, could be due to a weather system overloading the automation of the aircraft.
On another flight, the co-pilot stated that a few seconds after engaging the autopilot, the nose of the aircraft had tilted down and the aircraft had begun to descend to an altitude of between 1,200 and 1500 feet (365 to 460 meters).
As in the other flight, the aircraft's low altitude warning system sounded a warning. The captain disconnected the autopilot and the aircraft began to climb.
In the second incident, the co-pilot stated that he could "think of no reason why the plane would sting so aggressively."
But in both incidents, the reports indicated that the problem did not seem to be related to the new automated anti-stall system suspected of contributing to the Lion Air crash in Indonesia in October 2018, during which 189 people were killed. killed.
In this accident, the data indicates that pilots also had difficulty with repeated dive commands from the aircraft before it crashed into the Java Sea.
However, the anti-stall system only activates if the autopilot is disabled, according to Boeing.
