7.14.o Engine Bleed Air System
Two compressor discharge bleed air connections are located
after the centrifugal compressor stage of the engine from which
air is taken for the bleed air system. The extraction of equal
amount of bleed air from both ports is achieved by connecting
both discharge lines by means of a common manifold. The
bleed air system provides airflow to the cabin
pressurization/heating system (primary system) and the
pneumatic de-ice system (secondary system).
Important To prevent a hot start, no bleed air is extracted from the
engine during engine starting.
Note For further information concerning bleed air systems,
refer to paragraph Heating, Ventilation, Defrosting & Air
Conditioning and Cabin Pressurization in this section.
