Airbus a320 APU system question answers

[@vishalthakur3671]

Question 12 Apu is the current answer because Apu avail means it is powering the system already Avail light in Apu comes after the blue on light …….in the case of External power switch Avail light comes first and when you press it external source Blue on light comes on now it will take priority over the Apu……….in the question it’s mentioned Both Are on Avail light which means external power is not switched on so Apu is still running .
