What responsibilities does a pilot-in-command have regarding navigation?

The pilot-in-command holds the primary responsibility for the overall safety and operation of the flight, and this encompasses several critical tasks related to navigation. Ensuring safe navigation is a fundamental duty, which involves planning and following a route, maintaining situational awareness, and adjusting for any changes in flight conditions or air traffic.

Verifying position is also crucial for the pilot to maintain accurate awareness of the aircraft's location relative to the intended flight path, airspace boundaries, and any obstacles. This often requires cross-referencing navigational charts, using onboard navigation systems, and continuously monitoring the aircraft's progress.

Moreover, compliance with regulations is essential for safety and professionalism. This includes adhering to air traffic control instructions, following established flight rules, and being aware of any temporary airspace restrictions.

In contrast, the other choices are either too narrow in focus or miss the overarching responsibilities of a pilot. Focusing only on landing disregards the significant aspects of navigation that need to be managed throughout the flight. Managing in-flight entertainment and supervising passenger safety, while important, do not encapsulate the critical navigational duties that the pilot-in-command must prioritize during the flight.
