This publication continues the discussion on Airbus flight control laws started with Airbus A330 Normal Law: Putting fly-by-wire into perspective. Covered here are the reconfiguration laws that become effective when Normal law can no longer function. It is intended to provide additional insight into these flight control laws for the pilots who fly them and for interested aviation enthusiasts.
While these publications focus on the A330 specifically, the principles for each flight control law generally apply to the other Airbus fly-by-wire aircraft. Differences exist between the various models in the computer and hydraulic/electric architecture that operate the flight controls and while these physical differences are not covered here, the focus is on the aspects that affect the pilot and behavior differences between models is discussed.
