FLIGHT INTO KNOWN ICING CONDITIONS (1/3)
THE AURAL STALL WARNING SYSTEM DOES NOT FUNCTION PROPERLY IN ICING
CONDITIONS AND SHOULD NOT BE RELIED UPON TO PROVIDE ADEQUATE STALL
WARNING IN ICING CONDITIONS AND AFTER LEAVING ICING CONDITIONS, IF ICE
General
1 - Icing conditions exist when the OAT 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, sleet or ice crystals).
2 - Icing conditions also exist when the OAT 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 cowlings.
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.
Boots are automatically cycling at the optimum time to assure proper ice removal. Correct operation of the system
can be checked observing the corresponding green advisory light illumination at each boot inflation impulse. If
correct operation cannot be confirmed, do not enter or leave as soon as possible icing conditions.
Apply "LEADING EDGES DEICING FAILURE" emergency procedure.
