Anti ice, rain Flashcards
Which statement about the wing anti-ice system is correct?
a) The wing anti-ice system can be used to de-ice all leading edge devices.
b) The wing anti-ice system can be used to de-ice the three inboard leading edge slats
only. The leading edge flaps and outboard leading edge slats cannot be de-iced.
c) The wing anti-ice system can be used to de-ice all leading edge slats. The leading
edge flaps cannot be de-iced.
d) No statement is correct
The wing anti-ice system can be used to de-ice the three inboard leading edge slats
only. The leading edge flaps and outboard leading edge slats cannot be de-iced.
When the WING ANT-ICE switch is selected to ON in flight:
a) The stickshaker and minimum maneuver speed bars on the speedtape move
upward. Stickshaker logic remains set for icing conditions for the remainder of flight,
regardless of subsequent WING ANTI-ICE switch position.
b) The stickshaker and minimum maneuver speed bars on the speedtape move
upward, as well as VREF. The speedbars and VREF will be adjusted downward
again when the WING ANTI-ICE switch is positioned to OFF
c) The stickshaker and minimum maneuver speed bars on the speedtape move
upward, as well as VREF. Stickshaker logic remains set for icing conditions for the
remainder of flight, regardless of subsequent WING ANTI-ICE switch position.
d) Nothing will change on the speed tape.
The stickshaker and minimum maneuver speed bars on the speedtape move
upward. Stickshaker logic remains set for icing conditions for the remainder of flight,
regardless of subsequent WING ANTI-ICE switch position.
Illumination of an amber COWL ANTI-ICE light indicates:
a) An overpressure condition exists.
b) An over temperature condition exists.
c) The respective cowl anti-ice valve is in transit, or the cowl anti-ice valve position
disagrees with the respective ENGINE ANTI-ICE switch position.
d) Both A and B are correct.
a) An overpressure condition exists.
. Refer to the Thermal Anti-Ice (TAI) CDS indication. TAI shown at the top Left side
of each indicator indicates:
a) If amber, an over temperature condition exists in the duct downstream of the engine
cowl anti-ice valve.
b) If green; the cowl anti-ice valve is closed and the related engine anti-ice switch is
OFF
c) If green, the cowl anti-ice valve is open and the related engine anti-ice switch is ON
d) None of the above.
c) If green, the cowl anti-ice valve is open and the related engine anti-ice switch is ON
Which window(s) are heated with the LEFT FWD WINDOW HEAT Switch ON?
a) L2, L3, L4, L5

When is wing anti-ice used?
a) On the ground, when icing conditions exist or anticipated.
b) As a de-icer or anti-icer in flight.
c) In flight, prior to ice accumulation.
d) All of the above are correct.
d) All of the above are correct.
The R ELEV PITOT light is illuminated. What does this indicate?
a) The right elevator pitot probe is blocked.
b) Malfunction in the pitot probe system.
c) The right elevator pitot probe is not heated.
d) Both A and B are correct.
c) The right elevator pitot probe is not heated.

c) Windshield wipers may be operated on a dry windshield.
d) None of the above.
a) Each wiper is operated by a separate control.
How are the alpha vanes heated?
a) By Actuating the LEFT or RIGHT FWD window heat switch.
b) Whenever wing anti-ice is being used.
c) Whenever the alternate static ports are heated.
d) By actuating the A or B PROBE HEAT switches.
d) By actuating the A or B PROBE HEAT switches.
