What should be the first action if smoke is noticed within the flight deck?

When smoke is detected within the flight deck, the immediate priority is to ensure safety and maintain control. Communicating the issue promptly is vital for several reasons. It allows the flight crew to alert air traffic control and any other relevant personnel about the situation, ensuring that rescue and emergency procedures can be initiated as necessary.

This action also keeps all crew members informed, enabling them to coordinate their responses effectively. Quick and clear communication helps prevent confusion and allows for a swift assessment of the situation, which is critical in emergencies.

While turning off electrical devices, ventilating the space, or activating the fire suppression system are important steps to take in response to smoke, none should take precedence over effectively communicating the issue. The potential for an emergency necessitates that all crew members are aware and can act together to address the situation safely.
