Applicable to: -
- Flight preparation/limitations
APU fuel consumption with the APU ON (APU GEN OFF and APU BLEED OFF):
APU ON (IDLE)

The flight crew should take into account the severity of forecast icing conditions. The wing anti-ice will be lost if the remaining engine bleed air supply system becomes inoperative.
- After engine start
  • ENG BLEED (AFFECTED) pb-swOFF
  • X BLEED OPEN
If both PACKs are operative:
If Wing Anti-Ice is not required:
  • PACK FLOW selectorLO
The PACK FLOW selector must be set to LO due to precooler performance.
If Wing Anti-Ice is required:
  • PACK (AFFECTED) pb-swOFF
If one PACK is inoperative:
  • PACK FLOW selectorHI
- Before takeoff
  • APU MASTER SW pb-swON
  • APU START pb-swON
- For takeoff
Set at least one air conditioning pack to off, or use the APU bleed air supply system.
- After takeoff
If the APU has been used to supply the air conditioning during the takeoff:
  • APU BLEED pb-swOff
- In flight
If Wing Anti-Ice is required and both PACKs are operative:
  • PACK (affected side) pb-swOFF
In the case of failure of the remaining engine bleed air supply system, or in the case of failure of the associated engine:
Apply the associated ECAM procedure, then

Apply the AIR ENG 1+2 BLEED FAULT ECAM procedure.
CAUTION:
Reset ENG BLEED pb-sw as requested by ECAM procedure even if the ENG BLEED pb-sw is placarded inoperative as per MMEL 36-11-01.
In the case of failure of the opposite PACK:
  • PACK (AFFECTED) pb-swON
