APU to pack takeoff configuration (when selested on Take off FMC page):
• left engine bleed valve is closed : L ENG OFF light is illuminated
• APU provides air to ADP C1 and to left pack
• center bleed isolation valve is closed
• the right engine provides bleed air to ADP C2
• the right pack valve is closed, and the R PACK OFF light is illuminated
Should have written : When APU to Pack is used there is only one engine bleed AND one pack
Sad I cannot find a good schematics dispaly from my doc.
