787 cargo fire detection system
Not sure if we have any specialists on pprune able to answer these questions.
I understand the 789 has 28 photo-optic area smoke and fire detectors for the cargo hold. I assume these are purely smoke (rather than temperature) sensors.
Are the forward and aft cargo hold temperature sensors (as displayed on the synoptic) different units......is there a single sensor for each hold or are they multiple like the fire detectors?
