DITCHING pb.............................................................................................................................. ON
Outflow valve, pack valves, and avionic ventilation inlet and extract valves close.
This prevents de-icing fluid from entering the aircraft. Avionic ventilation is in a closed circuit with
both fans running. In view of the low OAT, there is no time limit for this configuration.
Note: If the “VENT AVNCS SYS FAULT” warning appears, reset the AEVC circuit breaker at
the end of the aircraft de-icing procedure.

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.

At least 60 s after APU start, or on completion of spraying operation :
APU BLEED..........................................................................................................................ON
PITOTS and STATICS (ground crew)....................................................................................CHECK
GROUND EQUIPMENT...................................................................................................... REMOVE
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.
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: ALL
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
PROTECTIVE COVERS....................................................................................................INSTALL
Install protective covers and plugs to protect the aircraft and engines from snow and ice.
WATER SYSTEM DRAINING
Applicable to: ALL
Drain the water system, if the OAT requires it, as shown below :
