Ice & Rain Protection Flashcards
What sub-systems does ice and rain protection
include?
Wing and stabilizer anti-ice system; engine ice
protection system; ADSP/TAT heating system;
windshield heating system and windshield 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 MODE knob shall be selected?
Only if the crew is certain that there is no ice
accretion on the airplane (AOM 9-12-30)
What does the ICE SPEED RESET position on the
ICE PROTECTION MODE do?
It resets the stall protection (LSA bands) to nonicing
condition settings and removes the STALL
PROT ICE SPEED CAS message (AOM 9-12-30)
When is the APU icon and associated flow line on
the ICE PROTECTION synoptic page displayed?
On the ground only (AOM 9-12-30)
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 Ice Protection 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 may the WHS operate in a power savings
mode?
If the airplane system is fed by a single
generator (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)
Will the Anti-Ice system monitor icing conditions
and automatically activate in all flight phases?
Yes (AOM 9-12-50)
Whenever the XBLEED is closed and the right
bleed is the only source available, the anti-ice
system is?
Inoperative (AOM 9-12-50)
What is the maximum operating altitude for antiice
single bleed operation?
20,000 ft (AOM 2-50)
List the 3 ICE PROTECTION MODE knob settings/
temperatures for takeoff:
ENG if the temperature is between 5°C and 10°C
with visible moisture; ALL if the temperature is
lower than 5°C with visible moisture; and AUTO
for all other conditions (AOM 9-12-50)
If the MODE knob is in ALL for takeoff, when will
the white A-I WINGSTAB ARMED CAS message
go to white A-I WINGSTAB ON?
When wheel speed is greater than 30 kts
AOM 9-12-50
When the ICE PROT MODE knob is in the AUTO
position and the ice detector recognizes the icing
condition, at what point will the ice protection
system be activated in flight?
Whenever the airplane is above 1,700 ft AGL
or 2 minutes in the air, whichever occurs first
(AOM 9-12-50)
When will the wing and stabilizer anti-ice system
automatically be turned off after the airplane
leaves icing conditions?
After 2 minutes (AOM 9-12-50)
