Detection fire APU on B777-300
Dear all,
I would like to ask you about an exercise I have in a sim . After takeoff we loose one engine(severe damage) , EO SID then DET FIRE APU, then radar vectors for an approach, go around, second approach and landing. According to QRH DET FIRE APU , Plan to shut down the APU as soon as practical. According to your professional opinion when I have to shut down the APU and why.
Thank you in advance for your help.
