Which one of the following is not a responsibility of the Pilot in Command?

The Pilot in Command (PIC) has several key responsibilities that are fundamental to ensuring the safety and effectiveness of flight operations. Among these, maintaining the aircraft in an airworthy condition is primarily the responsibility of the aircraft owner and the maintenance personnel. While the PIC must ensure that the aircraft is in a condition to be flown safely and must conduct pre-flight inspections, the formal responsibility for the overall airworthiness lies with those who maintain the aircraft and with regulatory standards set by aviation authorities.

In contrast, the final authority for aircraft operation rests with the PIC, as they make crucial decisions regarding the flight. During emergencies, the PIC has the authority to deviate from established rules to ensure the safety of the flight. Familiarity with flight information is essential for the PIC to make informed decisions during flight planning and execution, ensuring compliance with regulations and safe navigation.

Thus, while the PIC plays a vital role in overseeing safe operations during flight, direct maintenance and airworthiness management is outside of their defined responsibilities.
