The preliminary report from the investigation of LNI610 disagrees with you: https://reports.aviation-safety.net/2018/20181029-0_B38M_PK-... The AoA attack sensor was replaced prior…

Can something be obsolete if it is still extremely widely used? IIRC, Linux and FreeBSD both use a buddy allocator for physical memory, and I'm pretty sure it is used (in addition …

The comment you are responding to addresses the claim that the 737 max is not passively stable. It is less safe than other aircraft, but not because it requires active control for …

But they neglected maintenance when serious issues with the plane were apparent. The pilots of the flights prior to 610 noted that the two AoA sensor readings differed by ~20 degre…

The procedure that pilots are taught to override auto trim was unchanged, but I think that previous auto trim systems could also be "out muscled" just by pulling back on the yoke w…

No, it doesn't. The 737 max has software to prevent stalls in situations outside of the profile of normal flight. As does e.g. the A320.

It's interesting that you reach that conclusion. I'll fly 737 max. I won't fly Lion Air or Ethiopian Airlines. Southwest: fleet size 754, founded 1967, total of seven accidents wit…

The new system (MCAS) was not intended to take action in normal flight. It was intended the trim in certain scenarios (roughly high AoA + steep turn + high g + near stall), but on …

There already is a switch to disable auto trim. The pilots on the flight prior to 610 used it, as trained. The pilots on 610 did not.
