I think the idea behind is somehow different. That 707 auto feature was most probably designed as such ?
To me the use of the trim wheel to counter the unjustified activation of a protection is much more than a challenge, it is pure Experiment.
I believe that if it was the preferable solution, it would be the one mentioned in the Airbus AFM Temporary Revision.
I'm not a big fan of the double ADR OFF selection either but it is IMO a piece of cake compared to what A33Zab is suggesting.
Without any hesitation my recommendation, for what it worth, would be to install a very accessible switch to both pilots to simply cancel any undue activation of a protection.
It would be for sure a Tsunami in regards of the ideological concept as advertised by BZ, but on the technical side it would be nothing.
Am I asking for the unreasonable ... ?
