Which component routes conditioned air to the various pressurized compartments?

• A. Air conditioning distribution system
• B. Water separator
• C. Flow-limiting venturi
• D. Diverter valve

Answer: (A)

Routing conditioned air to every pressurized section is handled by the air conditioning distribution system. This network takes conditioned air from the environmental control system and delivers it through ducts to each compartment—cockpit, cabin, and any other pressurized zones—while using valves and flow controls to balance temperature and airflow. The water separator isn’t involved in directing airflow; it’s for removing moisture from other systems. A flow-limiting venturi helps regulate or measure flow but doesn’t by itself route air to compartments. A diverter valve is a component within the distribution system that helps direct air to different ducts, but the overall task of delivering conditioned air to all pressurized areas is the job of the air conditioning distribution system.
