Wiz the following comes from your own companies B777 QRH checklist instructions/ non normal checklists.
It must be stressed that for smoke that continues or a fire that cannot be positively
confirmed to be completely extinguished, the earliest possible descent, landing,
and evacuation must be done.
Indeed it does, and forms part of Boeings recomendations regarding handling such incidents repeated in the FCTM.
Please understand that by "Fire Indication" I meant cockpit annunciation. Obviously a fire confirmed by other indications (smoke, flame, heat) is a completely different thing and would indeed mean an evacuation.
It does not however form part of any individual checklist. Nor does it cover the case where it has not been positivley confirmed that a fire exists in the first place, or that indications are that a fire HAS been extinguished.
Are you suggesting that this paragraph means that any fire warning must necessarily lead to an evacuation, without seeking confirmation or otherwise from other sources?
