When is the onboard emergency checklist (OEC) utilized?

The onboard emergency checklist (OEC) is specifically designed to be utilized by flight attendants in situations where the Link or EFAOM (Electronic Flight Attendant Operations Manual) is not functioning as expected. This checklist serves as a critical reference tool that ensures all necessary emergency procedures are followed accurately, especially when standard operational resources are unavailable.

In scenarios where communication systems are down or access to the electronic manual is compromised, the OEC allows flight attendants to quickly reference essential protocols and safety measures, thereby enhancing the overall safety of the flight. It is a vital resource that supports crew members in effectively managing emergency situations without relying solely on technology, ensuring preparedness and response efficiency.

Other options may imply a broader or different use of the checklist, such as for pre-flight checks, general crew use during flight, or as part of the boarding process, which are not the primary functions of the OEC. The use of the checklist is particularly critical under malfunctioning conditions, reinforcing its targeted purpose within emergency management protocols.
