In an air carrier flight, is it required for a crewmember to have a flight engineer certificate to perform emergency FE functions?

In the context of air carrier operations, it is not required for a crewmember to hold a flight engineer certificate to perform emergency flight engineer functions. This is based on regulatory guidelines that provide flexibility during emergencies, allowing qualified personnel to step into roles to ensure the safety of flight operations.

During critical situations, the focus is on immediate response and safety rather than certification status. If a qualified individual, regardless of their certification as a flight engineer, possesses the necessary training and knowledge of the aircraft systems, they may assist in emergency functions. Such an approach is rooted in practical considerations, where handling an emergency effectively takes precedence over strict adherence to certification details.

This understanding underscores the importance of crew resource management and the capability of individuals to operate under pressing circumstances, emphasizing teamwork and the ability to act based on situational needs. Thus, while a flight engineer certificate is crucial for standard operations, it is not an absolute requirement for emergency functions.
