●● Amber CAWS ECS.
Answer: will illuminate anytime the system fails or is turned off


●● ECS will automatically shut down when.
Answer: the starter is activated


●● Air Cycle System.
Answer: Engine bleed air is drawn from either P3 or P2.5 stations
○ Single port for P2.5 and dual opposed ports for P3


●● Source of bleed air is automatically selected by.
Answer: the High Pressure Shutoff Valve


■ Above approximately 80% NG, the valve closes and P2.5 air is used


■ Below approximately 80% NG, the valve opens and P3 air is used

, ●● Bleed air passes through.
Answer: a flow control venturi
○ Regulates flow rate and pressure


●● Temperature control valve (TCV).
Answer: At the TCV the bleed air splits where variable amounts are
either supplied to the Heat Exchanger or to a mix point downstream of
the Cooling Turbine.


Depending on the selected temperature the TCV modulates to
either pass air through or bypass the Heat Exchanger and Cooling
Turbine.


●● temperature is cooler than desired.
Answer: TCV will bypass more air past the heat exchanger.


●● temperature is warmer than desired.
Answer: TCV will duct more air into the heat exchanger allowing it to
be cooled


●● Temperature sensor.
Answer: downstream of the TCV will limit the
