Icing Limitations
2-14-1
Limitations
Flight in icing conditions is only approved with all ice protection systems, generator 1 and
generator 2 serviceable.
Flight in icing conditions is prohibited when the Propeller De-ice caution is active.
During flight in icing conditions, if there is a failure of any of the aircraft ice protection systems
exit icing conditions. Immediately request priority handling from Air Traffic Control to facilitate a
route or an altitude change to exit the icing conditions.
During flight in icing conditions or flight with any visible ice accretion on the airframe, the
following flap maximum extension limits apply:
With operational airframe pneumatic de-ice boots
15° FLAP
After failure of the airframe pneumatic de-ice boots
0° FLAP
In the event of a balked landing go-around with residual ice on the airframe, the flaps should
not be retracted from the 15° position.
Flight in freezing rain, freezing fog, freezing drizzle and mixed conditions causing ice accretion
beyond the protected areas of the pneumatic boots is not approved.
The aircraft must be clear of all deposits of snow, ice and frost adhering to the lifting and
control surfaces immediately prior to takeoff.
In the event of a balked landing (go around) with residual ice on the airframe, the landing gear
and flaps may not fully retract after selection.
The left wing inspection light must be operative prior to flight into forecast icing conditions at
night.

Icing Conditions
Icing conditions can exist when:
−
The Outside Air Temperature (OAT) on the ground and for takeoff, or Static Air
Temperature (SAT) in flight, is 10 °C or colder, and visible moisture in any form is present
(such as clouds, fog or mist with visibility of one mile or less, rain snow, sleet and ice
crystals)
−
The OAT on the ground and for takeoff is 10 °C or colder when operating on ramps,
taxiways or runways, where surface snow, ice, standing water, or slush may be ingested
by the engine, or freeze on the engine, or the engine nacelle
−
There are visible signs of ice accretion on the aircraft.
