B737 Cargo Fire Checklist
We have in some of our B737-300s a Cargo Fire Protection Sytem installed. In the checklist for a cargo fire the last two items left me a bit puzzled. According to the checklist you have to switch of the recirculation fan, which i can understand (no recirculation of fumes), and "One pack switch......Off" (plan to land at the nearest suitable airport).
Why do i have to switch one pack off? Why is it not specified which pack is to be switched off?
Any answers?
