A true nerd moment...
DC-10-30 Has a total of 6 firex bottles, 2 x firex each
for all 3 engines. The same two firex bottles
for #2 Engine also serve the APU.
Some operators(BCAL)elected to fit a '3rd' APU firex
bottle which was mounted in the stab bay, aft of rear
pressurised bulkhead.This could be fired manually @ F/Es or GND
Panel or automatically dependant what the APU FIRE controller
sensed.
One of my old bosses accidentally fired a #2 pos next to me
(during testing)one day - I staggered round deaf and totally
unbalanced afterwards...
BAe146?
