Boeing 737MAX- Automated Crashes

Explore the technical, sociological, and organizational factors behind the Boeing 737 MAX crashes in this comprehensive conference talk. Delve into the design flaws of the Maneuvering Characteristics Augmentation System (MCAS), inadequate risk assessment, and certification process failures that led to two fatal accidents. Examine the aircraft's flight characteristics, sensor issues, and the challenges pilots faced in countering automatic nose-down trim movements. Gain insights into the aviation industry's certification practices, including the delegation of evaluation work to manufacturers. Learn about the global response to the 737 MAX grounding and the potential changes in certification processes by aviation authorities worldwide. Understand the complex interplay of factors that contributed to this aviation crisis, including aircraft design, pilot proficiency, maintenance issues, and regulatory oversight.
