In a few months, several pilots reported the abnormal situation of 737MAX8 anonymously.

In the past few months, a number of pilots have anonymously uploaded anomalies in this database about driving a Boeing 737 MAX 8 aircraft and expressed concerns about the safety of the aircraft.
The safety of the Boeing 737 MAX 8 (ie Boeing 737-8) model has received worldwide attention in two consecutive accidents that killed more than 100 people in five months. Although the Federal Aviation Administration (FAA) issued a report saying that the model is still airworthy, more and more countries and airlines decided to temporarily suspend the commercial operation of the Boeing 737 MAX 8, pending further confirmation of its security.
On this occasion, the US Fox News, the Associated Press and other media, through the database compiled by the National Aeronautics and Space Administration (NASA), found that in the past few months, several pilots have anonymously uploaded driving on this database. The Boeing 737 MAX 8 aircraft experienced anomalies and expressed concerns about the safety of the aircraft. According to reports, these concerns are mainly concentrated on the aircraft's autopilot system. The problem usually occurs when the aircraft takes off and when the pilot heads down and the pilot tries to pull up its height. The two recent air crashes occurred during the take-off period, and the planes crashed within 13 minutes and 6 minutes after takeoff.
According to reports, a captain raised dissatisfaction with the Boeing 737 MAX 8 flight manual, saying it was "insufficient" and "almost criminally incomplete." Another organic long-term aircraft requires an "emergency transmission to fly" and considers this to be "a dangerous signal."
According to a report quoted by the Associated Press, when a captain set up the aircraft as an autopilot, the first officer immediately shouted "down", and then the cabin sounded warning "Don't sink, don't sink". The captain immediately disconnected the autopilot and resumed the climb.
"Out of concern for the (737) MAX 8, we think (this situation) deserves your attention." The captain wrote in the report, "I think the best (for the cause of the anomaly) guess is empty The rapid fluctuations are caused by short-term weather factors that interfere with the aircraft's automation system.
In another report, a captain stated that the aircraft had a downward tilting of the nose within seconds of the automatic driving and that the aircraft began to descend at a rate of 365 to 460 meters per minute. Like the aircraft mentioned above, the aircraft's low-altitude warning system also issued an audible warning, and the captain immediately disconnected the autopilot and the aircraft began to climb.
"I can't think of any reason why the plane is so swiftly swooping," said the aircraft copilot.
The above reports submitted in the NASA database are anonymous, so it is impossible to know exactly where the abnormal situation occurred and the airline to which they belong.
On October 29 last year, a Boeing 737 MAX 8 passenger plane carrying 189 people from Indonesian Lion Air was plunged into the sea 13 minutes after taking off. On March 10 this year, Ethiopian Airlines took off a passenger plane carrying 157 people. After 6 minutes, it crashed near the capital Addis Ababa, and there was no life in the two air crashes.
At present, the reasons for the two accidents have not yet been determined, but it is known that both passenger planes have requested to return to the air and have abnormal flight data.
According to the US Federal Aviation Administration, approximately 350 Boeing 737 MAX 8 aircraft are registered for operation worldwide. At present, more than 40 countries or airlines have announced the suspension of the commercial operation of the Boeing 737 MAX 8, pending further confirmation of its security. Boeing told Fox News on the 12th that security is their "top priority" and they "have confidence in the security of the 737 MAX." Two airlines in the United States that use the Boeing 737 MAX 8 (Southwest Airlines and American Airlines), have not yet received reports from the pilots about stall prevention technology, and will continue to use the aircraft.
