ICE AND RAIN Flashcards
How many wing anti ice schedules are there?
Two, when the slats are extended the AILC schedules a higher temperature.
In the event of an engine failure, there will be no way to provide air to the respective wing for ice protection
False, use the wing anti-ice cross bleed selector knob to route air from the good engine to both wings.
What is the maximum speed for the operation of the windshield wipers?
250 KIAS
If ice is detected on one of the ice detector probes, the respective ice protection systems will automatically be activated
FALSE
When are the probes automatically heated?
When one engine is started and its generator comes on line
What will be seen on the N2 gauges when the wing anti ice system is activated
The arc will turn white up to 77% to indicate power setting that may be required for adequate ice protection.
What happens if a Cowl Anti Icing duct ruptures?
The escaping pressurized bleed air is contained inside the outer duct
If the pilot selects the HI position of the windshield heat switch, additional heat will be applied to all four aircraft cockpit windows
FALSE. Only the windshields are heated at the higher level.
The FAST position of the window wipers will always override any other position selected
FALSE. The last position selected by either pilot will control both wipers.
What occurs when the wing anti-icing switch is selected ON?
The modulating SOVs will vary their position based on commands from the dual-channel AILC computer, and will maintain a hotter temperature schedule if the slats are extended
