Where can unserviceable seals be found?

Unserviceable seals can be primarily found in the Flight Satchel, which is an essential tool for flight attendants that contains various required items for ensuring passenger safety and compliance with regulatory standards. The Flight Satchel is specifically designed to hold materials that are used on every flight, and unserviceable seals would need to be secured in a location that is readily accessible for inspection and management.

In contrast, while the cockpit and other options may house equipment related to the operation of the aircraft, they are not specifically designated for the storage or management of unserviceable seals. The cockpit is focused on operational controls and instruments essential for piloting the aircraft. A crew member's personal bag is primarily for personal belongings and items not related to flight operations or safety protocols. Onboard supplies storage would typically involve items that are still operational and maintain the normal service levels during a flight, rather than items that are unserviceable.

Thus, the Flight Satchel is the key area for maintaining such unserviceable equipment, ensuring they are managed correctly in alignment with safety protocols.
