-
two presssure transducers which monitor the pressure in the ducts,
-
two Bleed-air Monitoring Computers (BMC1 and BMC2) which receive information from the sensors. They monitor the system and control its operation,
-several temperature sensors (provided for regulation) which detect overtemperature in ducts and give temperature indication.

This system is installed in the MID and AFT fuselage and contains:
-a crossbleed valve which isolates or connects the right and left bleed air and distribution systems,
-
an APU bleed load valve which is a part of the APU. This valve controls the bleed air flow from the compressor of the APU when the supply system of the engine is off or does not operate,
-
an APU bleed check valve in the APU duct which protects the APU against bleed air from the engine(s).
C. The Ground Supply of Compressed Air (Ref. 36-13-00) (Ref. Fig. 007) This system is installed in the lower MID fuselage on the left side and includes a ground connector behind panel 191DB. A check valve is installed inside the ground connector. This stops the loss of air when the ground supply unit is not connected. The HP air is supplied to the distribution systems through the ground connector.

D. Environment Protection (Ref. 36-14-00)
-Protection of the Pylon and the Nacelles This system is installed between the engine pylons and the fuselage. It has a protection function of the wing leading edge and the nacelle. If there is a major leak in the pneumatic system, a door opens and the pressure is released.
ENGINE BLEED AIR SUPPLY SYSTEM - DESCRIPTION AND OPERATION
__________________________________________________________
R 1. General_______ The purpose of the engine bleed air supply system is to: - select one of the two different compressor stages of the engine HP compressor in agreement with the supplied pressure - regulate the bleed air pressure in order to prevent too high pressures - regulate the bleed air temperature in order to prevent too high temperatures. 2.
