Pneumatics
What is ACSC?
Air Conditioning System Controller
There are 2 of them
They automatically control the bleed air selection
MANUAL selection is on the BLEED Air panel
Pneumatics
What does isolation valve (ISOL) do?
Provides inner connection and isolation capabilities between left and right sides of the bleed air manifold
ACSC controlled, cannot be opened when any engine is supplying bleed air to the manifold or any anti-ice ON
Pnematics
If APU is running during takeoff how does it switch back to engine bleeds?
If APU is operating during takeoff, switch to engine bleed occurs with gear up and flaps 20°or less, and thrust levers retarded from TOGA
Pneumatics
On approach how does it transfer from the engines to APU for the bleeds
We flaps are greater than 20 or landing gear down
Does ACSC allow APU to supply bleed air to wing anti-ice systems?
No
Pneumatics
How does APU LCV interlock protection work
- It will not allow both the engines and the APU to supply the manifold at the same time
- ACSC commands the engine bleed valves to close before opening the APU LCV
- Control logic prevents the APU from supplying bleed air to the Anti-ice systems
- If the APU is supplying bleed air to the manifold and either the cowl or wing anti-ice system is selected ON, the APU LCV is automatically closed and the engine bleed valves are commanded open
What controls the wing anti-ice system
AILC- Anti-ice leak detection controller.
CRJ900 uses pressure regulated engine bleed air from a single common bleed manifold
What happens to N2 when wing anti-ice is turned on
A white arc appears
What’s the message you get when you test the ice detection system
ADS HEAT test OK
It test both the ice detection and air data sensor heat controller systems (ADSHC)
Briefing

- Special considerations:
a. Windshear
b. Weather
c. Anti-ice holdover time
d. Use if radar
e. Use of Continuous Ignition - Taxi route
