> I thought that Airbus makes the only airliners with no feedback when there are dual inputs applied

This factoid will not die on HN. Conflicting inputs on an Airbus are handled by averaging and an audible "DUAL INPUT" cockpit warning.[1]

In the case of AF447, the co-pilot used his "Priority Takeover" button which meant only his control inputs were in effect.

If you wanted to say there is no physical feedback, then you would be correct.
