What should be done if smoke is detected in the cabin?

When smoke is detected in the cabin, the immediate and appropriate action is to alert the crew. Crew members are trained to handle emergencies, including smoke detection, and can initiate the necessary safety protocols. By notifying them promptly, they can assess the situation, determine the source of the smoke, and implement the correct emergency procedures, which may include locating the source, using fire extinguishers, or preparing for evacuation if necessary.

This timely communication is critical because the crew has access to training and equipment to manage the situation effectively, ensuring the safety of all on board. They can also coordinate with pilots to prepare the aircraft for a landing if the situation escalates. Therefore, alerting the crew is essential for maintaining safety in the cabin.
