What does the term "pilot in command" refer to?

The term "pilot in command" refers specifically to the individual responsible for the operation of an aircraft. This designation is crucial as it indicates who has the authority and responsibility for the safety of the flight and its passengers. The pilot in command makes critical decisions related to the operation of the aircraft, such as navigation, communication, and adherence to regulations. This role encompasses both the legal responsibilities and the accountability for the aircraft's condition and the well-being of everyone on board.

Understanding this term is essential for pilots, as the pilot in command must ensure they meet certification and experience requirements and are fit for the flight. This designation is established under federal regulations to promote safety and clarify the chain of command within the flight crew. In comparison, aspects such as the most recent flight experience, presence of a flight instructor, or the filing of a flight plan are not directly related to the overarching responsibility of commanding the aircraft during operations.
