Ice and Rain Protection Flashcards
What sub-systems does ice and rain protection include?
Wing and stabilizer anti-ice systems; engine anti-ice systems, ADSP/TAT heating system; windshield heating system and windshield and rain protection system. AOM 9-12-01
When may icing conditions exist?
Whenever the OAT on the ground or for takeoff or TAT in flight is 10*C or below and visible moisture in any form is present. AOM 2-50
Where can performance data/limits for operations in icing conditions be found?
In the performance section and/or OPERA. AOM 2-50
When may the ICE SPEED RESET position on the ICE PROTECTION panel be selected?
In accordance with the checklist, only if the crew is certain that there is no ice accretion on the airplane. AOM 2-50
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. AOM 9-12-30
When is the APU icon and associate flow line on the ICE PROTECTION synoptic page displayed?
On the ground only. AOM9-12-30
Can the APU bleed be used as a bleed source for ice protection?
No, except for ground tests. AOM 9-12-50
How does the Engine Anti-Ice system protect the engine air inlets from ice formation?
By extracting hot air from the engines. AOM 9-12-50
How does the Wing and Stabilizer Anti-Ice System protect the wing and stabilizer leading edges from icing formation?
It uses hot air from the pneumatic system. AOM 9-12-50
How can the Wing and Horizontal Stabilizer Ice Protection Systems test be initiated?
By pressing the ice protection TEST button on the ICE PROT panel. AOM 9-12-50
How many ice detectors are on the airplane and where are they located?
Two; left and right side of the nose section. AOM 9-12-50
How does the Windshield Heating System (WHS) protect the windshield from ice and fog formation?
It uses electrical power to heat the windshield. AOM 9-12-50
When will the WHS operate in a power savings mode?
If the airplane system is fed by a single DC source. AOM 9-12-50
Does WHS operate if the system is fed by battery power?
No. AOM 9-12-50
How are the ADSP/TAT probes heated?
Electrically. AOM 9-12-50
