Ice & Rain Protection

Question 1

What sub-systems does ice and rain protection

include?

Answer 1

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)

Question 2

When may icing conditions exist?

Answer 2

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)

Question 3

Where can performance data/limits for operations

in icing conditions be found?

Answer 3

In the performance section and/or OPERA

Question 4

When may the ICE SPEED RESET position on the

ICE PROTECTION MODE knob shall be selected?

Answer 4

Only if the crew is certain that there is no ice

accretion on the airplane (AOM 9-12-30)

Question 5

What does the ICE SPEED RESET position on the

ICE PROTECTION MODE do?

Answer 5

It resets the stall protection (LSA bands) to nonicing
condition settings and removes the STALL
PROT ICE SPEED CAS message (AOM 9-12-30)

Question 6

ice protection?

Answer 7

No, except for ground tests (AOM 9-12-50)

Question 8

How does the Engine Ice Protection System

protect the engine air inlets from ice formation?

Answer 8

By extracting hot air from the engines

AOM 9-12-50

Question 9

How does the Wing and Stabilizer Anti-Ice System
protect the wing and stabilizer leading edges
from icing formation?

Answer 9

It uses hot air from the pneumatic system

AOM 9-12-50

Question 10

How can the Wing and Horizontal Stabilizer Ice

Protection Systems test be initiated?

Answer 10

By pressing the ice protection TEST button on

the ICE PROT panel (AOM 9-12-50)

Question 11

How many ice detectors are on the airplane and

where are they located?

Answer 11

Two; left and right side of the nose section

AOM 9-12-50

Question 12

How does the Windshield Heating System (WHS)

protect the windshield from ice and fog formation?

Answer 12

It uses electrical power to heat the windshield.

AOM 9-12-50

Question 13

When may the WHS operate in a power savings

mode?

Answer 13

If the airplane system is fed by a single

generator (AOM 9-12-50)

Question 14

Does WHS operate if the system is fed by battery

power?

Answer 14

No (AOM 9-12-50)

Question 15

How are the ADSP/TAT probes heated?

Answer 15

Electrically (AOM 9-12-50)

Question 16

Will the Anti-Ice system monitor icing conditions

and automatically activate in all flight phases?

Answer 16

Yes (AOM 9-12-50)

Question 17

Whenever the XBLEED is closed and the right
bleed is the only source available, the anti-ice
system is?

Answer 17

Inoperative (AOM 9-12-50)

Question 18

What is the maximum operating altitude for antiice

single bleed operation?

Answer 18

20,000 ft (AOM 2-50)

Question 19

List the 3 ICE PROTECTION MODE knob settings/

temperatures for takeoff:

Answer 19

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)

Question 20

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?

Answer 20

When wheel speed is greater than 30 kts

AOM 9-12-50

Question 21

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?

Answer 21

Whenever the airplane is above 1,700 ft AGL
or 2 minutes in the air, whichever occurs first
(AOM 9-12-50)

Question 22

When will the wing and stabilizer anti-ice system
automatically be turned off after the airplane
leaves icing conditions?

Answer 22

After 2 minutes (AOM 9-12-50)
