ICE and RAIN PROTECTION Flashcards
What is the source of heating for wing and cowl
anti-ice
6th or 10th stage bleed air
When is cowl anti-ice required to be ON during ground operations
OAT ≤ 10°C in visible moisture
(fog with visibility 1 sm or less, rain, snow, sleet, ice crystals),
OAT ≤ 10°C on contaminated ramps, taxiways or runways
When is cowl anti-ice required to be ON during flight
TAT ≤ 10°C in visible moisture
(such as clouds, rain, snow, sleet, or ice crystals) (except when SAT is ≤ -40°C),
or when ICE is annunciated
When is wing anti-ice required to be ON during ground operations
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
When is wing anti-ice required to be ON during flight operations
TAT ≤ 10° C in visible moisture
(such as clouds, rain, snow, sleet, or ice crystals)
with airspeed < 230 KIAS except when SAT is ≤ -40° C, or when ICE is annunciated
What is a good ICE detector test indication
ICE caution message, the ICE switchlight illuminated, ADS HEAT TEST OK advisory message
What is the purpose of the Wing A/I cross-bleed switch
To allow the bleed air from one engine to anti-ice the opposite wing
What occurs with the Windshield Heat on LOW
All 4 panels are heated to 24°C
What occurs with the Windshield Heat on HIGH
Side windows are heated to 24°C and both windshields are heated to 41°C
