- The bleed air precooler assembly maintains a constant outlet temperature with the aid of a..
- modulating valve, sensor, and temperature control circuit.
- Hot bleed air used for air-conditioning is cooled in a heat exchanger by...
- ram air
- To create a greater cooling effect, atomized water is sprayed across the inlet of the bleed air system secondary heat exchanger by the..
- water aspirator.
- One purpose of the fan in the bleed air system cooling turbine and fan assembly is to prevent...
- turbine overspeeding.
- Bleed air system water seperators remove 70 to 85% of the moisture that accumulates in the conditioned air. This is accomplished as a result of...
- rapid expansion.
- The bleed air system water seperator anti-icing system prevents the condenser bag from icing by keeping the turbine..

- The bleed air system component that causes the aircraft cooling turbine to slow down when an icing condition occurs is the...
- Ice control screen.
- What air source ventilates the cockpit when smoke or fumes are discharged from the airconditioning system?
- Atmospheric air.
- When a fighter aircraft air-conditioning system is being operated on the ground, the ram air necessary to cool the bleed air flowing through the heat exchangers is provided by the..
- ejector valve.
- How is the warning light in the cockpit activated if duct pressure on a fighter air-conditioning system becomes excessive?
