SMOKE/FUMES/AVNCS SMOKE - GENERAL (Cont'd)
‐ After an ENG or APU failure, smoke may come from the faulty item via the bleed system and
be perceived in the cockpit and/or cabin. In such a case, it will be recirculated throughout the
aircraft, until it completely disappears from the air conditioning system.
‐ If only the AVIONICS SMOKE warning is triggered, the crew may suspect avionics smoke.
‐ If the smoke is detected while an equipment is declared faulty, the crew may suspect that smoke
is coming from this equipment.
‐ Avionics or forward galley smoke may be smelt, or may enter in the cockpit before ECAM
warning activation.
