operating cabin fans, since air blows to the inboard valve. Considering the low OAT, there is no
time limitation associated with this configuration.
The “CAB PRESS FWD OFV NOT OPEN”, “CAB PRESS AFT OFV NOT OPEN” and “COND LAV
+ GAL VENT FAULT” ECAM cautions will be triggered.
Disregard the associated procedure.
Note: On the ground with passengers on board, it is recommended to avoid packs inoperative
for longer than 20 min because comfort may be affected.
THRUST LEVERS.........................................................................................................CHECK IDLE
“AIRCRAFT PREPARED FOR SPRAYING”........................................... INFORM GROUND CREW
Applicable to: ALL
UPON COMPLETION OF THE SPRAYING OPERATION
DITCHING pushbutton.................................................................................................................OFF
OUTFLOW VALVE......................................................................................................CHECK OPEN
On the ECAM PRESS page, confirm that the outflow valve indication reaches the open green
position to avoid any unexpected aircraft pressurization.
CAUTION If spraying is performed with the engines not running, a small negative cabin delta
P may appear for a short time, just after selecting the ditching pushbutton to OFF.
During this time, do not open any doors or windows.
ENG BLEED................................................................................................................................ ON
At least 60 s after APU start, or on completion of spraying operation.

DE-ICING/ANTI-ICING REPORT..................................................................................... RECEIVED
The information from ground personnel who performed the de-icing and post-application check
must include (ANTI-ICING CODE) :
• Type of fluid used.
• The mix ratio of fluid to water (for example 75/25).
• When the holdover time began.
• Result of post application check : Aircraft critical parts are clean.
NORMAL PROCEDURE..................................................................................................... RESUME
Apply appropriate normal procedures. Pay special attention to the flight control check. In freezing
precipitation, perform the appropriate checks to evaluate aircraft icing. Base the decision on
whether to takeoff, or to re-protect the aircraft, on the amount of ice that has built up on the critical
surfaces since the last de-icing, as revealed by a personal inspection from the inside and outside
of the aircraft. Make this inspection before the holdover time expires, or just before takeoff.
Note: If the fuselage has been sprayed, there is a risk of de-icing fluid ingestion by the APU air
intake, resulting in specific odors, or SMOKE warnings. Thus, consider APU BLEED OFF
during takeoff.
SECURING THE AIRCRAFT FOR COLD SOAK
Applicable to:
Note: At beginning of a cold soak, due to a transient temperature difference between fluid in the
reservoir and the system piping, the G RSVR UNDERFILLED caution may be triggered on
the ECAM. Check the reservoir quantity in the upper half part of the norm filling range. The
caution may disappear with the operation of the green electrical pump.
After switching off all bleeds and before switching off AC power :
DITCHING pushbutton................................................................................................................ON
This closes the outflow valve, the pack valves, and the avionic ventilation inlet and extract
valves.
PARKING BRAKE.....................................................................................................................OFF
Check chocks in place, and release the parking brake to prevent brakes from freezing.
After switching off the batteries :
DITCHING pushbutton.............................................................................................................. OFF
CAPT SEAT.....................................................................................MOST FORWARD POSITION
To facilitate access to the avionic bay, since seat operation becomes difficult once the
mechanism is cold-soaked.
