1
Q

What is the source of heating for wing and cowl anti-ice

A

6th or 10th stage bleed air

2
Q

When is cowl anti-ice required to be ON during ground operations

A

OAT ≤ 10°C in visible moisture in any form (fog with visibility 1 sm or less, rain, snow, sleet, ice crystals)

OAT ≤ 10°C on contaminated ramps, taxiways or runways

3
Q

When is cowl anti-ice required to be ON during flight

A

When icing condition exist or are anticipated, or
When ICE is annunciated by the ice detection system.
Icing conditions exist in flight when TAT is 10°C or below and visible moisture in any form is encountered except when the SAT is -40°C or below.

4
Q

When is wing anti-ice required to be ON during ground operations

A

OAT ≤ 5°C in visible moisture (fog with visibility 1sm or less, rain, snow, sleet, ice crystals),

OAT ≤ 5°C on contaminated runways.

If Type II, Type III or Type IV deicing fluid has been applied, select wing anti-ice ON just prior to thrust increase for takeoff.

5
Q

When is wing anti-ice required to be ON during flight operations

A

When icing conditions exist and airspeed is less than 230 KIAS, or when ICE is annunciated by the ice detection system.
Icing condition exist in flight when TAT is 10°C or below and visible moisture in any form is encountered, except when SAT is -40°C or below.

6
Q

What will indicated a satisfacory test when the ICE DET TEST switch light is pressed?

A

ICE switch light illuminates
ICE caution message is displayed on EICAS
ADS HEAT TEST OK advisory message id displayed on EICAS

7
Q

What is the purpose of the Wing A/I cross-bleed switch

A

To allow the bleed air from one engine to anti-ice the opposite wing

8
Q

What occurs with the Windshield Heat on LOW

A

All 4 panels are heated to 24°C

9
Q

What occurs with the Windshield Heat on HIGH

A

Side windows are heated to 24°C and both windshields are heated to 41°C

10
Q

When should the Windshield Heat be switched OFF?

A

When OAT is 30°C or above
