MCAS, or Maneuvering Characteristics Augmentation System, provides consistent airplane handling characteristics in a very specific set of unusual flight conditions. MCAS now contains multiple enhanced protections: Measurements from two Angle of Attack (AOA) sensors will be compared. Each sensor will submit its own data to the airplane’s flight control computer. MCAS will only be activated if both sensors agree. MCAS will only be activated once. MCAS will never override the pilot’s ability to control the airplane using the control column alone. MCAS ON 737 Max The Maneuvering Characteristics Augmentation System (MCAS) flight control law was implemented on the 737 MAX to mitigate the aircraft's tendency to pitch up because of the aerodynamic effect of its larger, heavier, and more powerful CFM LEAP-1B engines and nacelles. The stated goal of MCAS, according to Boeing, was to provide consistent aircraft handling characteristics at elevated angles of attack in certain unusual
