Engineer on Boeing crash...they should ground MAX8 until pilots are trained
From an engineering point of view it seems to me that the bean counters have prevailed over the real engineers at Boeing. They kept on evolving a 1967 aircraft design for over 50 years, presumably to avoid the massive costs of a complete redesign, testing and certification. The MAX 8 has pushed the 737 envelope so far that they had to mount the new, larger engines further out on the wings, otherwise they'd touch ground. However, moving the engines further out created a potential aerodynamic instability that could lead the aircraft into a stall. Rather than redesigning the wings (and incurring all the costs) they decided to use a very invasive software to automatically correct a detected stall. Then to save even more money they decided that this software would rely on the data from two sensors (instead of three) to determine the pitch of the aircraft - thus making it impossible to determine a safe pitch in case of sensor failure. Then, to squeeze even the last dollars out of their budget, they decided not to include all these new software functions in the manuals, which would have required additional pilot training, and so on. In summary, it seems to me that the MAX 8 is the result of the worst kind of "cost-saving engineering" that I would not accept out of a cheap plastic toy, let alone on a sophisticated aircraft that's supposed to carry millions of people safely around the world. Shame on Boeing. Their CEO and CFO should be sacked.
