波音公司为波音737 MAX系列飞机设计的MCAS系统全称为“机动特性增强系统”(Maneuvering Characteristic Augmentation System),用以在襟翼收上和飞机大迎角时增强俯仰特性。 MCAS系统可以在大坡度转弯增加载荷因子,以及襟翼收上后速度接近失速速度时指令安定面往飞机低头方向配平飞机,以增强飞机的俯仰特性。MCAS系统只在襟翼收...

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 ...
The Max is outfitted with bigger, more fuel-efficient engines than earlier 737s, a change that shifted thecenter of gravity forwardand increases the potential for the nose to pitch up after take-off. Boeing created software known as the Maneuvering Characteris...
Boeing engineers began updating flight-control software called MCAS shortly after it was determined to have played a role in the crash of a Lion Air Max off the coast of Indonesia in October 2018. They were still working on the software when an Ethiopian Airlines Max crashed near Addis...

Former Boeing engineering test pilot Mark Forkner has been indicted in a Fort Worth, Texas Federal Court on multiple charges stemming from his involvement in the development of the MCAS system used in Boeing 737 Max airplanes. Prosecutors allege th...
That followed two fatal crashes attributed to problems with the aircraft’s automated Maneuvering Characteristics Augmentation System, or MCAS. Bangs said she was impressed with the FAA’s “right decision” to quickly ground the Max 9 on January 6, a move it was slow in making for the Max ...
