I'm using unstable as the FAA defines it in Federal Aviation Regulation Airworthiness Criteria Sec. 25.173 — Static longitudinal stability.
The 737 MAX, while more stable than the F-16, is not a stable aircraft as evidenced by the MCAS system Boeing installed.
So you’re saying when a 737 MAX is flying straight and level and not accelerating, if the pilot pushed or pulled on the yoke and then let go, the 737 MAX would not return to its original trimmed position?
Are you saying the MCAS is needed for this, and without the MCAS the 737 MAX would not return to its position as trimmed before the upset?
