Anti Ice Flashcards
When is power to the electrically heated probes applied?
Engine running
Wing anti-ice protection is applied to the ____ of each wing
Three outboard slat
Wing Anti-ice is on, what will the Wing Anti-ice VALVE lights do when the airplane lands?
Illuminate and remain on until wing anti-ice switch is turned off
If the left engine anti-ice switch is blank and its VALVE light is illuminated, what is the condition of the
left Engine Anti-ice Valve?
Signaled closed, and not closed
Wing anti-ice is on, what will the wing anti-ice valves do when the airplane lands?
Close
What is used to compute engine thrust limit corrections for engine anti-ice?
Engine anti-ice switch position
If the right wing anti-ice valve is stuck in the open position, why is the engine bleed air switch turned
off after landing?
Prevent engine bleed airflow to the right wing
How are the wing anti-ice valves controlled and operated?
Controlled electrically, operated pneumatically (pressure actuated)
The ICE DET light indicates that:
A fault has been detected in both ice detector units
Engine anti-ice automatic operation does not work on the ground.
True
The total air temperature (TAT) probe is only heated when airborne
T
In flight, when the Nacelle Anti-Ice switches and Wing Anti-Ice switches are in AUTO, and icing
conditions are detected, the respective anti-ice valves are commanded open.
T
In flight on the -300F when icing conditions are detected the respective anti-ice valves are
commanded open.
Automatically, if the switches are in the auto position
The ICING light on the -300F is an indication the engine or wing anti-ice is manually selected OFF or
an anti-ice valve is closed and engine/wing icing is detected.
T
What happens when Nacelle Anti-Ice is commanded on?
NAI valve opens and engine igniters operate continuously
