FLIGHT INTO KNOWN ICING CONDITIONS
General
1 – Icing conditions exist when the IOAT on the ground or in flight is + 13°C
or below, and
visible moisture in any form is present (clouds, fog with
visibility of one mile (1.6 km) or less, rain, snow, sleed or ice crystals).
2 – Icing conditions also exist when the IOAT on the ground is + 13°C or
below and
when operating on ramps, taxiways or runways where
surface snow, ice, standing water or slush may be ingested by the
engine or freeze on engine or nacelle.
NOTE :
Refer to Figure 5.4.1 to convert IOAT to SAT in flight.
SAT = IOAT – 2°C on the ground.
3 – Flight into known icing conditions is authorized when all airplane
equipment provided for ice protection is operating correctly. This
includes :
– Pneumatic deice system for inboard and outboard wing, for
stabilizers and for elevator horns.
– Propeller electrical deice system.
– Electrical heating system for both pitots and for the stall warning
incidence sensor.
– Windshield electrical deice system.
– Inertial separator.
Description of deice systems is presented in Chapter 7.13.
Ice accumulation thickness is monitored by the pilot on the L.H. wing leading
edge.
At night, a leading edge icing inspection light located on the fuselage
L.H. side, activated by the ”ICE LIGHT” switch, is provided.
