ICE AND RAIN PROTECTION
OPERATION IN ICING CONDITIONS
There is no temperature limitation for anti-icing system automatic
operation.
On ground:
- The TO DATASET MENU on the MCDU must be set to ENG
when OAT is from 5–10°C and:
- if there is any possibility of encountering visible moisture
up to 1700 ft AFE, or
- when operating on ramps, taxiways, or runways where
surface snow, ice, standing water, or slush may be
ingested by the engines, or freeze on engines, nacelles, or
engine sensor probes.
- The TO DATASET MENU on the MCDU must be set to ALL
when OAT is less than 5°C:
- if there is any possibility of encountering visible moisture
up to 1700 ft AFE, or
- when operating on ramps, taxiways, or runways where
surface snow, ice, standing water, or slush may be
ingested by the engines, or freeze on engines, nacelles, or
engine sensor probes.
In flight:
- The engine and wing anti-ice systems operate automatically, in
case of ice encounter when the ice protection mode selector is in
the AUTO position. If either one or both ice detectors are failed,
the crew must set the mode selector to ON when icing conditions
exist or are anticipated below 10°C TAT with visible moisture.
