1 SMOKE ORIGIN IDENTIFICATION AND FIGHTING
The crew tries to identify the smoke source by isolating systems.
Some guidelines may help the crew to identify the origin of smoke:
? If smoke initially comes out of the cockpit's ventilation outlets, or if smoke is detected in the cabin, the crew may suspect an AIR COND SMOKE. In addition, very shortly thereafter, several SMOKE warnings (cargo, lavatory, avionics) will be triggered. The displayed ECAM procedures must therefore be applied.
? Following an identified ENG or APU failure, smoke may emanate from the faulty item through the bleed system and be perceptible in the cockpit or the cabin. In that case, it will be re-circulated throughout the aircraft, until it completely disappears from the air conditioning system.
? If only the AVIONICS SMOKE warning is triggered, the crew may suspect an AVIONICS SMOKE.
? If smoke is detected, while an equipment is declared faulty, the crew may suspect that smoke is coming from this equipment.
According to the source he suspects, the crew will enter one of the 3 paragraphs:
1. IF AIR COND SMOKE SUSPECTED...
2. IF CAB EQUIPMENT SMOKE SUSPECTED...
3. IF AVNCS/ELECTRICAL SMOKE SUSPECTED OR SMOKE SOURCE CANNOT BE DETERMINED...
Since electrical fire is the most critical case, he will also enter paragraph 3 if he doesn't know the source of the smoke, or if the application of paragraph 1 and/or 2 has been unsuccessful.
This part of procedure consists of shedding one side, then the other. If unsuccessful, setting the electrical emergency configuration is the last means to isolate the smoke source.
When the flight crew sets the electrical emergency configuration following a smoke situation (whatever the case "AVNCS VENT SMOKE" ECAM warning triggered or not), the ECAM displays
ABNORMAL OPERATIONS
FIRE PROTECTION
the same ELEC EMER CONFIG procedure as the one displayed following the loss of main generators. However, as the flight crew has voluntarily set the electrical emergency configuration to attempt to isolate the smoke source, he must not try to restore the generators as requested by the ECAM. Therefore, the SMOKE/FUMES/AVNCS SMOKE paper procedure indicates that the flight crew must not reset the generators.
BOXED ITEMS
These items (applying SMOKE REMOVAL procedure, setting electrical emergency configuration, or considering immediate landing) may be applied at any time, in the procedure (but not before the immediate actions).
When necessary, the SMOKE REMOVAL procedure must be applied before the electrical emergency configuration is set. Indeed, in electrical emergency configuration SMOKE REMOVAL procedure cannot be applied, since manual control of cabin pressure cannot be selected.
Once the first step of the smoke removal procedure have been applied, the flight crew will come back to the SMOKE/FUMES/AVNCS SMOKE procedure, to apply the appropriate steps, depending on the suspected smoke source while descending to FL 100. Reaching FL 100, the smoke removal procedure will be completed.
