The aircraft has an Auxiliary Power Unit (APU) bleed-air supply and a crossbleed system installed in the AFT and Mid fuselage. The load compressor of the APU supplies the APU bleed air to the distribution system. The supply of the APU bleed air is controlled by the APU bleed control valve. When the APU bleed control valve is in the open position the Pressure Reducing Valves (PRV) of the engines close, and shut off the engine bleed-air supply. Thus the distribution system supplies the APU bleed-air to the user systems. It is not necessary to regulate the temperature, pressure and flow of the APU bleed-air because they agree with the user demand. The crossbleed system connects the left and right wing supply ducts. The left and right bleed-air systems work in correlation. A crossbleed valve isolates them from each other.
