Those are synonymous even for the pedants.
There are two pedants' arguments:
- If an aircraft
that has not demonstrated failed to demonstrate "static longitudinal stability" according to the FAR you kindly linked, may it be called "unstable"? Answer: For pedants, physicists and engineers no. It might still be stable but just not stable enough. For Joe Average and just about every journo, yes.
- If a system is augmenting logitudinal stability at high AOAs is this an "anti stall device"? For Boeing it is not, for most others including pedants, engineers and physicists, it is.
