摘要

Boeing has demonstrated the old and new versions of the MAX's Maneuvering Characteristics Augmentation System (MCAS) to pilots and regulators in its 737 MAX engineering cab simulator in Seattle. The MCAS is a new flight-con-trol-computer (FCC) function added to the MAX to enable it to meet longitudinal stability requirements for certification. However, the system is only needed to enhance stability with slats and flaps retracted at very light weights and full aft center of gravity (cg). The aircraft exhibits sufficient natural longitudinal stability in all other parts of the flight envelope without the MCAS to meet the rules. Boeing emphasizes that the MCAS is not an anti-stall or stall-prevention system, as it often has been portrayed in news reports.
