A320 APU Bleed Use
In the A320 if the Engine Fire pushbutton is pressed APU bleed should not be used in case of Eng. 1 Fire pb pressed and APU Bleed can be used with the cross bleed rotary switch in shut position in case of Eng 2 Fire pb pushed. Can someone please explain the reason why APU bleed should not be used. Is it to prevent a reverse flow?
