PARTICULAR PROCEDURES
FLIGHT INTO KNOWN ICING CONDITIONS (Cont’d)
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.
Ice protection procedures
1 – Prior to entering IMC, as a preventive :
If 05 C < IOAT <+ 135 C :
–”PROP DE ICE” switch ON. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
–”INERT SEP” switch ON. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
If – 155 C < IOAT < 05 C :
– All ”DE ICE SYSTEM” switches ON. . . . . . . . . . . . . . . . . . . . . . . . .
–”IGNITION” switch ON. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

–”INERT SEP” switch ON. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
When IOAT is below – 25°C, avoid operations of the ”AIRFRAME DEICE
SYSTEM” for a too long period because the boots could be damaged. The
”INERT SEP” switch must be left ON while the airplane remains in icing
conditions.
