3.5 HYDRAULIC SYSTEM
Description
The aircraft counts with 2 different hydraulic circuits to provide a certain redundancy in the
hydraulic supply of some elements. Part of the Hydraulic circuit 1 can be isolated and fed
through an electro-pump to keep the aircraft controllable in the case of an emergency.
Each circuit is pressurized by a pump powered by the engine and counts with a hydraulic
deposit. As mentioned previously, in case of the pressure of circuit one falling beyond a certain
threshold, part of the circuit is isolated and an electro-pump is activated. A diagram of the
system shows which elements are fed by each circuit:
The hydraulic circuit feeds the control surfaces, the variable sensitivity crank bell (ARTHUR), the
wheel brakes, the actuation of the landing gear, the high lift devices, the shock cones, the
airbrakes and the nose wheel steering.
The landing gear can be deployed in the case of an emergency by an emergency deployment
lever. The gear must be retracted at speeds above 240 kt to avoid the possibility of damage.
