- 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 illumination in green of
the status light around AIRFRAME DE ICE switch. If correct operation cannot be
confirmed, do not enter or leave as soon as possible icing conditions.
Perform emergency procedure Leading edges deicing failure, paragraph 3.11.
Ice protection procedures
▲ CAUTION ▲
Should conditions require it, apply these directives from beginning of
taxi onwards.
▲
Prior to entering IMC if OAT < 5°C and as long as under icing conditions (IMC and
OAT < 5°C) or if ICE DETECTED is displayed, whichever comes first :
1 - DE ICE SYSTEM mode switch MAN. . . . . . . . . . . . . . . . . . . . . . . . . . . . .
All deicing systems turn on
▲ CAUTION ▲
Inertial separator position affects engine parameters, particularly TRQ
and ITT. Care must be exercised when operating the inertial separator
or when increasing power with the inertial separator ON, to avoid
exceeding engine limitations.
▲
2 - All deicing systems Check ON. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
