But, like Dozy says, the Yoke has faults. There were accidents where the Yoke did not save? So SS has faults?
So with the Yoke shown to be fallible, the examination of the SS is:
1. Not necessary
2. Not relevant to this accident
3. Not sufficiently alarming so as to warrant a Grounding
4. All of the above.
5. None of the above.
Likewise, though the A0A would seem to have been helpful, (and it was on the a/c, but INVISIBLE), should the AoA be eliminated from the discussion? After all, how many accidents were not prevented by the presence of the AoA indicator?
Inquiring minds want to know.
