Max Anti Ice and Rain Flashcards
Which Flight Deck windows are heated?
L/R 1 & 2
What happens if an overheat condition is detected in windows L1/R1 or L2/R2?
Automatically remove power from the window heat system and illuminate the OVERHEAT light for the associated window.
An overheat condition occurs when the embedded temperature probes sense window temperature exceeds approximately 43°C.
The OVERHEAT light remains illuminated until the window has cooled; however, the system must be manually reset by resetting the WINDOW HEAT switch OFF, then ON.
The Engine Anti-Ice System uses engine bleed air to prevent ice formation on which part(s) of the engine?
Engine cowl lip
Using bleed air from the 4th and 10th stages.
What does the green TAI indicate above the N1 indicator?
When engine TAI is turned on.
TAI indicates the valve is open and supplying bleed air to the cowl with the ENG ANTI-ICE switch ON.
What does an amber TAI indicate above the N1 indicator?
Cowl anti-ice valve disagrees with the ENG ANTI-ICE switch position for more than 8 seconds.
What causes the ENG ANTI-ICE light to illuminate?
TAI has been inhibited due to a system failure or engine core anti-ice valve has failed in the closed position.
What causes the COWL ANTI-ICE light to illuminate?
Overpressure condition in the associated duct downstream of the engine cowl anti-ice valve.
The Wing Anti-Ice System uses engine bleed air to prevent ice formation on which part(s) of the wing?
Three inboard leading edge slats using bleed air.
How does wing anti-ice affect stall logic?
Adjust stall warning logic to increase stick shaker and minimum maneuver speed for the remainder of the flight.
What occurs if wing anti-ice is used during takeoff?
Wing anti-ice valves will close automatically to preserve thrust
At lift-off, the WING ANTI-ICE switch will trip OFF to match the valve position.
Which parts of the aircraft are electrically heated?
Pitot tubes
AOA vanes
TAT probes
L1/R1, L2,R2 windows are also electrically heated
