ICE AND RAIN PROTECTION
OPERATION IN ICING CONDITIONS
Maximum Temperature for Anti-icing Operation ...................10°C
Minimum Temperature for Manual Anti-Icing Operation .......-40°C
Single engine or single bleed maximum altitude operation in icing
conditions ....................................................................15000 ft
Holding configuration:
Landing Gear....................................................................UP
Flaps.................................................................................UP
Minimum Airspeed ...........................................................200 KIAS
NOTE: - There is no temperature limitation for anti-icing system
automatic operation.
- Use Static Air Temperature (SAT) on ground or for takeoff
operations and Total Air Temperature (TAT) for operations in
flight.
- Icing conditions may exist whenever the Static Air Temperature
(SAT) on the ground or for takeoff, or Total Air Temperature
(TAT) in flight, 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,
taxi ways, 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.
- Notwithstanding ice detector monitoring, the crew remains
responsible for monitoring icing conditions and for manual
activation of the ice protection system if icing conditions are
present and the ice detection system is not activating the ice
protection system.
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.
• DO NOT USE APU BLEED AS PNEUMATIC SOURCE
FOR ANTI-ICING SYSTEM.
