Do you think everything is linked to Anti ice?
No.
Only those lines which include mentions to
"One pack must be closed when wing anti-ice is in use due to precooler performance.
L1 X BLEED (IF ENG FIRE PB NOT PUSHED)...............OPEN
L2 X BLEED pb-sw must be opened to have symmetrical wing anti-icing."
&
"If ENG FIRE pb-sw pushed:
XBLEED ............. SHUT
WING ANTI ICE............OFF
AVOID ICING CONDITIONS"
I don't have access to a simulator any more - if you get a chance please investigate.
I was caught out once by this so won't forget.
