ICING CONDITIONS
Applicable to: ALL
Icing conditions may be expected when the OAT (on ground and for takeoff), or when the TAT
(in flight) is at or below 10 °C, and there is visible moisture in the air (such as clouds, fog with low
visibility of one mile or less, rain, snow, sleet, ice crystals) or standing water, slush, ice or snow is
present on the taxiways or runways.
WARNING Pilots must turn on the engine anti-ice system, when temperature and visible
moisture meet these criteria, and should not wait until they see ice building up.
OPERATIONS IN ICING CONDITIONS
Applicable to: ALL
FLIGHT IN ICING CONDITIONS
Engine anti-ice
ENGINE ANTI ICE must be ON during all ground and flight operations, when icing conditions
exist, or are anticipated, except during climb and cruise when the SAT is below -40 °C.
ENGINE ANTI ICE must be ON before and during a descent in icing conditions, even if the
SAT is below -40 °C.
Wing anti-ice
WING ANTI ICE may either be used to prevent ice formation, or to remove ice accumulation
from the wing leading edges.
WING ANTI ICE should be selected ON, whenever there is an indication that airframe icing
exists. This can be evidenced by ice accumulation on the visual ice indicator (located between
the two cockpit windshields), or on the windshield wipers.

CAUTION 1. Extended flight, in icing conditions with the slats extended, should be
avoided.
2. If there is evidence of significant ice accretion and to take into account ice
formation on non heated structure, the minimum speed should be :
In configuration full, VLS +5 kt, and ‐ the landing distance must be
multiplied by 1.1.
‐ In configuration lower than FULL, VLS +10 kt, and the landing distance in
CONF 3 must be multiplied by 1.15.
3. If there is evidence of ice accretion on de-iced parts (WING ANTI ICE
inoperative) of the airframe, the minimum speeds should be :
‐ In clean configuration, VLS + 15 kt.
‐ In CONF 1, 2, 3, FULL, VLS + 10 kt, Refer to 99 Duref Cible QRH
or Refer to STLO-ABN-80-B LDG CONF/APPR SPD/LDG DIST
FOLLOWING FAILURES - BLEED for landing distance determination.
SEVERE ICE ACCRETION
Applicable to: ALL
Icing conditions are severe when there is approximately 5 mm of ice accretion on the airframe.
RAIN REPELLENT (IF INSTALLED)
Applicable to: ALL
If the rain repellent is operative, the flight crew should only use the rain repellent in moderate to
heavy rain.
GROUND OPERATIONS IN HEAVY RAIN
Applicable to: ALL
When the aircraft is parked on the ground during heavy rain, it can take rainwater into the avionics
ventilation system via the open skin air inlet valve.
To prevent this, the following procedure must be applied :
After landing :

This closes the avionics ventilation system, preventing rainwater from entering.
