Claim:
An architecture for a braking system for an airplane fitted with a plurality of undercarriages each carrying a plurality of wheels, at least some of which are fitted with brakes, the architecture comprising at least two braking computers each having two modules such that in each computer, one of the modules controls a first fraction of the brakes and the other module controls a second fraction of the brakes complementary to the first, the architecture being configured to operate in any one of the following modes of operation: a first normal mode in which both modules of one of the braking computers are active for controlling all of the brakes and both modules of the other of the braking computers do not actively control the brakes; a second normal mode in which both modules of the other braking computer are active for controlling all of the brakes and both modules of the one of the braking computers do not actively control the brakes; and an alternative mode in which one module of one of the braking computers and one module of the other braking computer are active for controlling all of the brakes.
