Presumably all airliners have similar switches and procedures for isolating and eliminating a smoke source. Plainly this procedure wasn't enough to save SR111: how often does it work in practice? Is this just some theoretical fantasy that keeps the flight crew busy while the plane is burning up? I would hope there are some success stories. -- -Stephen H.
