MCAS in detail on the 737 MAX

This presentation takes a close look at the details of MCAS on the 737 MAX, how it came about, what changes were made and how it now works.

This presentation does not discuss the management decisions by Boeing, the FAA oversight, the blame games or the regulations put into place since the accidents. This is all covered in my first presentation “The 737 MAX and MCAS from development to fix” which is available on my YouTube channel.
