Ice and Rain Protection Flashcards
What subsystems does ice and rain protection include.
1) Wing and Stab AI systems,
2) Engine AI systems,
3) ADSP/ TAT heating system
4) Windshield heating system
5) Windshield rain protection system
When may icing conditions exist
Whenever the OAT on the ground or for takeoff or TAT in flight is 10 deg C or below and visible moisture in any form is present.
Where can performance data/limits for operations in icing conditions be found
I -Preflight
When may the ICE SPEED RESET position on the ICE PROTECTION MODE knob be selected
Only if the crew is certain that there is no ice accretion on the airplane.
What does the ICE SPEED RESET position on the ICE PROTECTION MODE do?
It resets the stall protection (LSA bands) to non-icing condition settings and removes the STALL PROT ICE SPEED CAS message
When is the APU icon and associate flow line on the ICE protection synoptic page displayed
On the ground only.
Can the APU bleed be used as a bleed source for ice protection
No, except for ground tests
How does the Engine Anti Ice system protect the engine air inlets from ice formation
By extracting hot air from the engines
How does the wing stabilizer anti ice system protect the wing and stabilizer leading edges from icing formation
It uses hot air from the pneumatic system
How can the wing and Horizontal Stabilizer Ice protection systems test be initiated
By pressing the the ice protection TEST button on the ICE PROT panel.
How many ice detectors are on the airplane and where are they located
Two, left and right section of the nose section.
How does the windshield heating system (WHS) protect the windshield from ice and fog formation.
It uses electrical power to heat the windshield.
When may the WHS operate in a power savings mode.
If the airplane system is fed by a single engine.
Does the WHS operate if the system is fed by battery power.
No
How are the ADSB/TAT probes heated.
Electrically
