There is so much doublespeak here. If it is less stable than required for airworthiness then it is not airworthy. Can we agree on that?

- na85 7y agoSure, but that doesn't mean it's unstable.
- petilon 7y agoIf it is not stable enough then it is unstable. Where do you draw the bar on stability, if not airworthiness?
- na85 7y ago>If it is not stable enough then it is unstable. Nope, sorry, that's not what stability and instability mean. Stability means it will return to equilibrium if disturbed, but the issue with the MAX is that it requires a positive force gradient per the Part 25 Airworthiness Regulations, which the MAX does not exhibit in a specific part of the envelope. Stability is not a binary condition. The MAX is longitudinally stable in every part of the flight envelope. "Not airworthy" does not equate to "unstable". Those two terms are orthogonal.
