MCAS Explained

The Maneuvering Characteristics Augmentation System (MCAS) was designed to enhance the handling characteristics of the Boeing 737 MAX 8. It was intended to make the aircraft behave similarly to the older 737 NG models, especially at high angles of attack. The system automatically engaged to push the nose of the aircraft down if it sensed an impending stall. However, the system relied on data from a single angle of attack (AoA) sensor, making it vulnerable to incorrect readings. In the accidents, faulty AoA sensor data triggered the MCAS, which then repeatedly pushed the nose of the aircraft down, overwhelming the pilots. The pilots were unaware of the MCAS activation, and they struggled to counteract the system's actions. The original design did not provide pilots with sufficient information about the MCAS and its operation. This lack of transparency and pilot training on the system contributed to the tragic outcomes. The MCAS system has been updated, with changes that now incorporate data from multiple AoA sensors. The software updates also limit the authority of MCAS and include a system to alert pilots if the AoA data is inconsistent.
