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 SAT is between 5°C and 10°C with visible moisture.
- The TO DATASET MENU on the MCDU must be set to ALL when
SAT is below 5°C with visible moisture
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.
NOTE: - Icing conditions may exist whenever the Static Air
Temperature (SAT) on the ground or for takeoff, or Total Air
Temperature (TAT) inflight, is 10°C or below and visible
moisture in any form is present (such as clouds, fog with
visibility of one mile or less, rain, snow, sleet, and ice
crystals).
- Icing conditions may also exist when the SAT on the ground
and for takeoff is 10°C or below when operating on ramps,
taxyways, 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.
CAUTION:
ON GROUND, DO NOT RELY ON VISUAL ICING
EVIDENCE OR ICE DETECTOR ACTUATION TO TURN
ON THE ANTI-ICING SYSTEM. USE THE
TEMPERATURE AND VISUAL MOISTURE CRITERIA AS
SPECIFIED ABOVE. DELAYING THE USE OF THE ANTI-
ICING SYSTEM UNTIL ICE BUILD-UP IS VISIBLE FROM
THE COCKPIT MAY RESULT IN ICE INGESTION AND
POSSIBLE ENGINE DAMAGE OR FLAME-OUT.
