Who is responsible for monitoring enroute and alternate airport weather?

The pilot in command holds the responsibility for monitoring enroute and alternate airport weather. This is critical for safe flight operations as the pilot in command must ensure that all weather conditions are suitable for departure, enroute navigation, and landing. By continuously assessing weather reports and updates, the pilot in command can make informed decisions regarding route alterations or alternate airports to ensure the safety of the aircraft and its occupants.

While other crew members, such as the co-pilot, may assist in gathering weather data, the ultimate responsibility lies with the pilot in command, who must integrate this information into the flight management process. The dispatch officer plays a role in planning and initial weather assessments prior to departure, but during the flight, it is the pilot in command who actively monitors and responds to changing weather conditions.
