The B-747 has four hydraulic systems. Systems 4, 1 and 2 are used for providing pressure to the brake system. Each system is pressurized by an engine driven pump (EDP) and an air driven pump (ADP) which move due to the air circulating in the pneumatic system. Therefore, when the APU is working and providing pressurized air to the pneumatic systems, ADP's may provide pressure to the hydraulic systems. ADP number 1 is used to provide hydraulic pressure to the body landing gear steering function, to assist steering during pushback turns.  2, fiche 1, Anglais, - air%2Ddriven%20pump
