Why mount the extinguisher behind you? It would be better placed on the pax side floor so you can get at it quickly, as trying to reach behind you in a panic whilst trying to get belts off as you see flames licking up the windscreen isn’t going to end well
Plus on a safety side, how is it secured? It looks well strapped down to me (which is good, as it won’t come loose in an accident and smash you in the head) but then how easy is it to take it out quickly?
Good thread though, keep it coming
