Anti-ice, Rain Flashcards
Which flight deck windows are both anti-iced and anti-fogged?
The CA’s and FO’s forward windows
When is power to the electrically heated probes applied?
Anytime an engine is running
Wing anti-ice protection is applied to the ___ of each wing
Three outboard slats
Wing anti-ice is on, what will the Wing Anti-ice VALVE lights do when the airplane lands?
Illuminate and remain on until the 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
Is it necessary to change either aircraft or cabin altitude in the event the outer pane of the windshield cracks with no visible deformation?
No
What is the condition of the engine anti-ice valve with the switch ON and the VALVE light illuminated?
Signaled open, and closed or in transit
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)
How are the engine anti-ice valves controlled and actuated?
Electrically controlled, pneumatically 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. (T/F)
True
The total air temperature (TAT) probe is only heated when airborne. (T/F)
True
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/F)
True
In flight on the -300F when icing conditions are detected, the respective anti-ice valves are commanded open…(when)
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/F)
True
The automatic ice detection system on the -300 detects airplane icing in flight and is inhibited on the ground. (T/F)
True
The wiper panel on the -300F contains the following features:
Two independent selector switches, Intermittent operation position, Low and High position
The Captain and First Officers forward windshields have independent wiper selectors. (T/F)
True
What happens when Nacelle Anti-Ice is commanded on?
NAI valve opens and engine ignitors operate continuously
Is Wing Anti-Ice available on the ground?
No, wing A/I is inhibited on the ground
