The engine bleed air flow control valve is set to high flow by the ACS under what 6 conditions?
The cabin air distr. system receives conditioned bleed air from the bleed air system and distributes it through a lower duct system. Cooled air from the AC system is routed through 2 evaporators and into the upper duct distribution duct system. Used cabin air is exhausted through the primary and secondary outflow valves.
