PARTICULAR PROCEDURES
FLIGHT INTO KNOWN ICING CONDITIONS (Cont’d)
2 – When operating under IMC :
– All ”DE ICE SYSTEM” switches ON. . . . . . . . . . . . . . . . . . . . . . . . .
–”IGNITION” switch ON. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

CAUTION
SHOULD CONDITIONS REQUIRE IT, APPLY THESE DIRECTIVES
FROM BEGINNING OF TAXI ONWARDS
CAUTION
DO NOT OPERATE THE INERTIAL SEPARATOR IF THE AIRSPEED
EXCEEDS 200 KIAS. THERE IS NO SPEED LIMITATION WHEN
THE INERTIAL SEPARATOR IS IN FIXED POSITION
If a high speed descent (> 200 KIAS) is anticipated into known icing
conditions, position ”INERT SEP” switch to ON before accelerating. This will
avoid reducing speed below 200 KIAS during descent to set the inertial
separator.
IF AIRPLANE LEAVES ICING CONDITIONS, MAINTAIN ”INERT SEP” ON
AS LONG AS ICE THICKNESS ON NON–DEICED VISIBLE PARTS
EXCEEDS 15 mm (OR ½ INCH)
This will avoid ice fragments coming from propeller spinner and being
ingested by engine.
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
