explained in April: "On the MAX aircraft, when the critical point is reached, we still need automatic trimming. At high angles of attack, MCAS is different from speed trimming. Because MCAS bypasses the speed trim switch at design time, it is activated based on the angle...
show how Boeing originally designed MCAS as a simple solution with a narrow scope, then altered it late in the plane’s development to expand its power and purpose. Still, a safety-analysis led by Boeing concluded there would be little risk in the event ...
The flight control system will compare inputs from both Angle of Attack (AOA) sensors of the aircraft instead of one, and if there is a disagreement of 5.5 degrees or more with wing flaps retracted, MCAS will not be activated, Boeing explained. In case of an accident, MCAS will not be ...

新在2018年10月29日狮子航空610号班机空难发生不久后,FAA发现全球目前所有的737MAX(包含正在试飞的737 MAX 7和全系BBJ MAX)新增了一个MCAS系统,在失速及翻滚保护系统以防止机头仰角过大而失速或者发生翻滚下坠以及倒飞等现象,而当这个系统被无意触发后即使解除自动驾驶也会导致飞机下坠将近10秒钟,且飞机难以控制。
Boeing designed a system that adjusts the horizontal stabilizer to compensate for this, called the Maneuvering Characteristics Augmentation System (MCAS). When the flight control computer received data from the faulty sensors, it can determine that the airplane is stalled when it wasn’t. Commanding...
A Boeing spokesman called it a "relatively minor issue" and said the plane maker already has a fix in the works. He said the latest issue is not part of flight-control software called MCAS that Boeing has been working to upgrade since the first crash. ...

Kennedy says that during the design process Boeing “went to great pains to hide [MCAS] and how powerful it was.” The stabilizing system was designed specifically for the Max, since the fuel-efficient engines being added to the 1960s-designed plane affected the trim. The House committee foun...
