I fly A-320's for a major US airline and as part of our training we
area required to "fly" the airplane using these backup modes.  I assure
you, that from a practical point of view the airplane is virtually
uncontrollable in this mode and would be incapable of making anything
remotely resembling a controlled landing.

Additionally, there has been one instance where all flight computers
were turned off momentarily in flight.  Panic ensued... and the
aircraft nearly went out of control.
