What is the focus of regulations regarding "operational control" of a flight?

Regulations surrounding "operational control" of a flight primarily center on the authority and responsibilities of individuals involved in the flight's conduct. This includes the ability to initiate, conduct, and terminate a flight, focusing on the overall command and decision-making aspects that ensure the mission is executed as intended.

Operational control involves not just oversight but the ability to make critical decisions about the flight based on real-time data, circumstances, and operational norms. This authority ensures that safety, compliance with regulations, and mission objectives are maintained throughout the flight. Thus, it encompasses a broader understanding of command than just the individual roles of crewmembers or the technical manipulations of the aircraft itself.

While specific duties of crewmembers, control manipulation, and adherence to safety measures are all vital components of flight operations, they are subsets of the wider scope of operational control. They contribute to the effective execution of a flight but do not encompass the full authority and responsibilities that "operational control" implies. The correct answer emphasizes the critical nature of decision-making in flight operations.
