In my view, the whole case for what the computers can do with regard to stability is overstated. Even computers can't make rocks fly. The aerodynamic form of the a/c no matter how inefficient demands that it keep flying. As long as the integrity of the structure is preserved, it takes some effort (either on the part of the computers or the pilots or both) to keep the a/c from flying. This is the context in which we should look at direct law. It simply takes the computers out and lets the aerodynamics do its thing. The question is will the pilots be prepared to start flying stick and rudder at the drop of a hat?
