I may be one of the few -9a drivers with more than one extinguisher, but hear me out.
In the event of fire on the ground, I want something 'bigger', so behind the seat bulkhead/flap enclousure I have a 2 lb. BC...'cause you're getting out anyway, right?
For inflight or other emergencies where I really need instant access, I have a 1 lb upright between the seat backs. It would be Halon if it weren't so hard to get them here!
then for the passenger, who may be more able to deal with the distraction while I'm doing the other 'pilot stuff', I have one of those aerosol 'FlameOut' cans in their side pouch. I got mine at Wal-mart USA; again, hard to find in Canada for some stupid reason! also at a few of the pilot supply places.

So I'll go with those that say 3 is too many, until you need one!
