Speaking to reporters at Boeing's Seattle Flight Test Center last month, 737 Max chief project engineer Michael Teal explained that Boeing has performed most of the program's stability and. "Aircraft longitudinal stability is subject to airworthiness requirements. A primary flight display (PFD) like the one on 737 Max aircraft. The reports in various state-run media that China Southern Airlines, China Eastern Airlines, and Air China would seek payouts from the American aerospace giant come against the. We look into the reasons for the surprising price stability.

If perfect safety is what you are looking for, you would do well to do as aviation pioneer. So while the concept that the MCAS is improving the longitudinal stability of the B737 MAX, most likely due to engine nacelle longitudinal destabilization factors, this is the engineering argument offered for the MCAS system not being a pilot procedural controlled stability control, such as an elevator, in actuality the MCAS acts very similar.
