What is the main responsibility of the pilot in command?

The main responsibility of the pilot in command is to ensure the safety of the flight and the aircraft. This encompasses a broad range of duties, including making critical decisions regarding the operation of the aircraft, adhering to safety protocols, managing potential in-flight emergencies, and ensuring compliance with aviation regulations. The pilot in command must continuously assess the situation during the flight, including weather conditions, aircraft performance, and the well-being of any passengers or crew onboard.

While the comfort of passengers, maintaining technical specifications, and minimizing operational costs are important aspects of flight operations, they are secondary to the overarching responsibility of ensuring safety. The pilot in command's foremost duty is to prioritize the protection of everyone on board and the integrity of the aircraft itself, making safety the primary focus in all facets of their role.
