ENGINES/APU RUNNING
WARNING: APU OPERATION IS NOT RECOMMENDED DURING
THE AIRPLANE DEICING/ANTI-ICING PROCEDURE.
IF THE APU IS KEPT IN OPERATION DURING THE
DEICING/ANTI-ICING PROCEDURE, DAMAGE CAN
OCCUR TO IT. IF APU OPERATION IS ABSOLUTELY
NECESSARY, MAKE SURE THAT THE APU BLEED
AIR VALVE IS CLOSED, PACKS ARE SET TO OFF,
AND THE DEICING/ANTI-ICING FLUID IS NOT
APPLIED DIRECTLY TO OR NEAR THE APU AIR
INLET.
Parking Brake ............................................................... ON
Thrust Levers ................................................................ IDLE
Gust Lock...................................................................... ENGAGE
Doors ............................................................................ CLSD
Flaps ............................................................................. 0°
Pitch Trim ..................................................................... AS REQUIRED
To avoid APU fluid ingestion, it is recommended that pitch trim
should be set from 0° to FULL NOSE DOWN, hence fluid cascades
downwards and aft, keeping the stabilizer leading edge free from
the fluid drip that could be ingested by the APU.
However, operators are reminded to frequently inspect surfaces for
residue, as prescribed in the SNL 145-30-0006. This is applicable
mainly to fluid Types II, III and IV which may leave residue on the
aerodynamic quiet areas.
Engine Bleed ................................................................ CLOSED
APU Bleed .................................................................... CLOSED
Air Conditioning Packs.................................................. OFF
Packs should be off to avoid contamination of cabin air with fumes
generated from ingestion of fluids in engine/APU.
