What action must cabin crew take if they discover a prohibited item during a flight?

When cabin crew discover a prohibited item during a flight, it is crucial to confiscate and secure it from passengers. This action is essential to maintain safety and compliance with aviation regulations. Prohibited items might include weapons, explosives, or other materials that could pose a risk to the aircraft, passengers, or crew. By confiscating the item, crew members prevent any potential harm it might cause, ensuring the safety and security of everyone on board.

Securing the item also aids in managing the situation appropriately, allowing the crew to follow protocols for reporting and handling such items, which typically involve notifying the flight deck and following established procedures. This helps ensure that the crew can effectively manage any threats and maintain a safe environment for all passengers and staff on the flight.
