Electromechanical aeroplane brake control achitecture

The architecture has a first power supply box (B1) supplying power to actuators (1, 2) of first wheels (L1, R1) of first and second landgears, respectively. A second power supply box (B2) supplies power to complementary actuators (3, 4) of the first wheels of the first landgear and actuators of second wheels (R2) of the second landgear. A third power supply box (B3) supplies power to actuators of second wheels (L2) of the first landgear and complementary actuators of the second wheels of the second actuator. A power bus (AC2) supplies power to a fourth power supply box (B4). The fourth power supply box supplies power to complementary actuators of the second wheels of the first landgear and the first wheels of the second landgear.
