Duties of a Captain. The captain is responsible for the flight, the crew, the passengers and the aircraft. He has to ensure that all necessary checks are made before, during and after the flight. Typically, this role is responsible for weather checks, safety checklists, flight planning and flying the plane to its destination. Pilots also report any issues or changes during flights, take note of communications from air traffic control personnel and adapt flight plans if required.
