The concept of leaving AB Flight Laws behind, and with the select of a button, at that, is an odious proposal.
It infers that the simple, "DIRECT" method of flight control is superior to that of laboriously designed degrading (cascading?) electronic systems that are inferior to manual control in certain situations: THEY ARE.
This is all about PRIDE, and TURF, and MARQUE.
Nothing to do with flight control, or safety.
