What role does the pilot-in-command have during a flight?

The pilot-in-command holds full accountability for the flight operation, which encompasses a wide range of responsibilities critical to the safety and success of the flight. This role extends beyond just managing navigation or compliance with regulations; it involves making crucial decisions regarding flight safety, aircraft operation, passenger welfare, and adherence to regulations set forth by aviation authorities.

The pilot-in-command is ultimately responsible for ensuring that the aircraft is operated safely and according to the prescribed procedures, which includes making judgment calls about weather conditions, the functionality of aircraft systems, and the readiness of the crew. This accountability starts prior to departure, with a thorough preflight inspection and planning, and continues throughout the flight until the aircraft has safely landed and come to a complete stop.

While aspects such as passenger safety, navigation, and compliance with airport regulations are certainly important, they fall under the broader umbrella of the pilot-in-command's overall responsibility for the safe operation of the flight. In essence, the pilot must integrate all these factors into their decision-making process to ensure a successful flight.
