For the aircraft Ice Detection System, the ICE advisory message indicates
A). Icing conditions are detected with the wing and cowl anti-ice selected on and operating normally.
B). Icing conditions are detected with the wing or cowl anti-ice selected on and operating normally.
C). Icing conditions are detected with the wing and cowl anti-ice selected off.
D). Icing conditions are detected with the wing or cowl anti-ice selected off
Icing conditions are detected with the wing and cowl anti-ice selected on and operating normally.
For the aircraft Wing Anti-Ice System, selecting FROM RIGHT on the WING A/I CROSS BLEED selector (on the Bleed Air control panel) will:
A). Open the wing cross bleed valve and close the right wing anti-ice valve
B). Close the left wing anti-ice valve leaving only the right wing heated
C). Open the wing cross bleed valve and close the left wing anti-ice valve
D). None of the above
Open the wing cross bleed valve and close the left wing anti-ice valve
For the aircraft’s Air Data Probes and Sensors Anti-Icing components and operation, the following components are electrically heated:
A). Windows, windshields, and air data probes & sensors
B). Wing leading edges and engine cowls
C). Wing leading edges and air data probes and sensors
D). Windows, windshield and window wipers
Windows, windshields, and air data probes & sensors
The side cockpit windows are anti-iced.

When are the ice detectors deiced?
A). Never
B). Always
C). Only when ice is sensed
D). Whenever the engine cowls are deiced
Only when ice is sensed
What controls the temperature of the wing anti-icing?
A). The wing switch on the Anti-Ice panel
B). The position of the slats
C). The position of the flaps
D). The amount of ice sensed by the icing probe
The position of the slats
Wing anti-icing valves are spring loaded (fail-safe):
open
closed
Closed
The wing anti-ice valves will close when:
A). Bleed air supply pressure is removed
B). Loss of electrical power at the valve
C). The ice detector probes no longer sense icing conditions
D). Anti-ice duct failure is detected by the AILC
Bleed air supply pressure is removed
Loss of electrical power at the valve
Anti-ice duct failure is detected by the AILC
When wing anti-icing is selected, _______ arcs appear on the N2 gauges to remind the pilots that N2 core speed should be kept higher to ensure an adequate flow of bleed air.
