I find it interesting the link to the FAA recommended method of extinguishing still refers to halon nearly a generation later. Is it still legal in other countries?
"Fire Control Systems in Civil Aviation
There are 4 types of Fire Control Systems on commercial aircraft: (1) lavatory bottle extinguishing system, (2) on board portable extinguishers, (3) cargo compartment systems and (4) engine fire protection systems.
All lavatory bottle systems, cargo compartment systems and engine fire protection systems being installed today use halon 1301. All on board portable extinguishers being sold today use halon 1211. The popular belief is that the likelihood of seeing a halon free new commercial aircraft in the next five or perhaps even ten years is remote. "
