25.255, 25.655 and I think 25.161, and AC25-7B (or whatever the current revision was today).
I don't think you're reading that correctly. The maximum out-of-trim condition that must be correctable with the elevator is that resulting from 3 seconds of trim operation. This is *way* beyond 3 seconds.
The stab wins, it always does. I don't know of any modern jet where the elevator can overcome the stab in worst case scenarios. This should be pretty well covered in groundschool...
If the elevator always won, we wouldn't need the cutout switches.
