Who is referred to as the Captain of an aircraft?

The term "Captain" in the context of aviation refers specifically to the pilot in command (PIC) of the aircraft. This individual is responsible for the overall operation and safety of the flight. The Captain is distinguished by wearing four stripes on their uniform, which indicates their rank and level of experience.

This role encompasses more than just flying the airplane; the Captain is also accountable for making critical decisions, managing the crew, and ensuring that all safety protocols are followed. This direct link between the title "Captain" and the pilot who holds that responsibility is a fundamental aspect of flight operations.

In contrast, the first officer, also known as the co-pilot, typically holds a lower rank than the Captain and wears three stripes on their uniform. The flight attendant in charge focuses on cabin safety and passenger service rather than piloting the aircraft. Finally, the air traffic controller is responsible for managing the flow of air traffic but does not operate the aircraft itself. These distinctions further clarify the role of the Captain as the leader of the flight crew.
