Ice & Rain Protection Flashcards
What areas of the aircraft have ice accretion protection?
Wing leading edges, engine cowls, windows, and air data probes
What occurs to the N2 gauges when wing anti ice is selected on?
White arcs are displayed below 77%
How many ice detectors are there?
2
When will the detector provide an amber caution message on the EICAS? Advisory?
Show a caution when ice it detected with the anti-ice system is off. Shows advisory when the system is turned on
Why is bleed air output increased when the slats are extended?
The wing leading edge is then maintained at a higher temperature
How is hot bleed air routed to the slats from the piccolo tubes?
Via a telescopic duct to slat #1 then span wise to slats 2 and 3
What occurs after a wing overheat is detected?
The anti-ice valve automatically closes
A red WING OVHT displays on the Primary page
The wing is displayed in red on the Anti-Ice synoptic page
What occurs to the pitot heaters when an engine generator is operating and the probe switches are off during ground operation?
Half power is applied to the pitot heads
What occurs to the probes when an engine generator is operating and the probe switch are on during ground operations?
Half power is applied to the pitot heads
Full power is applied to the static ports and AOA sensors
What will occur if neither engine generator is operating and the probes are switched off during ground operations?
Nothing is heated
What will occur if neither engine generator is operating and the probes are switched on during ground operations?
Half power is applied to the pitot heads
Full power is applied to the static ports and AOA sensors
What function will the Air Data Sensor Heater Controller ADSDC perform after takeoff regardless of probe or generator switch position?
Full power is applied to everything
What will occur if the windshield heat switch is brought from off to high during ground operations?
A warm up cycle will occur prior to heating the windows up to the higher temperature
What 3 separate functions does the Ice DET TEST switchlight perform?
Icing Indicator
Ice Detection System testing
ADSHC System testing
