When a cockpit smoke indication occurs, what is the initial crew action sequence?

• A. Don oxygen masks, identify and isolate the source if possible, follow ECAM procedures, and prepare for possible diversion or landing.
• B. Immediately shut down all power and leave the cockpit.
• C. Ignore and continue as normal.
• D. Notify air traffic control only, no actions in cockpit.

Answer: (A)

When cockpit smoke is detected, the first priority is the crews’ safety and preserving control of the aircraft. Donning the oxygen masks immediately is essential for both pilots to ensure adequate oxygen and to minimize the effects of smoke inhalation while enabling the crew to think clearly and operate the aircraft.

Once the masks are on, quickly identify and isolate the likely source if possible. This involves using the ECAM/QRH guidance to assess which system triggered the warning and take the recommended actions to isolate that source or reduce its impact. This step is about narrowing down the cause without delaying critical flight control tasks.

After initiating the appropriate mitigations, follow the ECAM procedures. These are the step-by-step actions designed for the specific smoke indication, including system resets, switching or isolating affected circuits or equipment, and configuring the aircraft for safe continued flight or transition to a safe landing profile. Relying on the ECAM ensures actions are systematic and aligned with the airplane’s design.

Finally, be prepared for a diversion or landing at the nearest suitable airport if the situation cannot be resolved promptly or if the smoke/fire risk remains. This includes coordinating with air traffic control and cabin crew as needed to ensure a safe and orderly outcome.

Other options miss the core priority: providing immediate crew oxygen and following structured procedures to identify, isolate, and manage the source, while planning for a possible diversion if required.
