18.
Monitor the ECAM SDU. When the CTR LH pump indication changes from green cross-line (pump set to on but not in operation) to green in-line (pump in operation), on the panel 40VU:
-
release (out) the X FEED P/BSW
-
release (out) the L TK PUMPS 1 and 2 P/BSWs
-
release (out) the CTR TK L XFR P/BSW.
-
the crossfeed valve indication changes from green cross-line (valve closed) to green in-line (valve open)
-
the LEFT pump indications change from amber cross-line (pump not in operation) to green in-line (pump in operation)
-
the CTR LH pump indication changes from amber cross-line (pump not in operation) to green cross-line (pump set to on but not in operation).
On the EDAM SDU, the fuel quantityindication for the LH wing tankdecreases.
On the panel 40VU:
-
the OPEN and the ON lights of the XFEED P/BSW go off
-
the OFF lights of the L TK PUMPS 1and 2 P/BSWs come on
-
the OFF light of the CTR TK L XFR
P/BSW comes on. On the ECAM SDU:
-
the crossfeed valve indication changes from green in-line (valve open) to green cross-line (valve closed)
-
the LEFT pump indications change from green in-line (pump in operation) to amber cross-line (pump not in operation)
-
the CTR LH pump indication changes from green in-line (pump in operation) to amber cross-line (pump not in operation).

19. On the ECAM SDU:
-monitor the fuel quantity indications
-write down the LEFT wing-tank fuel-quantities indications when they have become stable.
20.
Use the fuel quantity indications (that you wrote down) to calculate the quantity of fuel removed from the aircraft, to operate the CTR TK L XFR pump. The quantity of fuel removed from the aircraft must be between 150 kg and 250 kg (330 lb and 550 lb).
21.
On the panel 40VU:
-
push (in) the R TK PUMPS 1 and 2 P/BSWs
-
push (in) the CTR TK R XFR P/BSW.
22.
Defuel the RH wing tank at a rate of 60 l/min (16 gal/min) (Ref. TASK 28-25-00-650-001).
23.
Monitor the ECAM SDU. When the CTR RH pump indication changes from green cross-line (pump set to on but not in operation) to green in-line (pump in operation), on the panel 40VU:
On the panel 40VU:
-
the OFF lights of the R TK PUMPS 1and 2 P/BSWs go off
-
the OFF light of the CTR TK R XFR
P/BSW goes off. On the ECAM SDU:
-
the RIGHT pump indications change from amber cross-line (pump not in operation) to green in-line (pump in operation)
-
the CTR RH pump indication changes from amber cross-line (pump not in operation) to green cross-line (pump set to on but not in operation).
On the EDAM SDU, the fuel quantityindication for the RH wing tankdecreases.
