The Cockpit Crew, also known as the Flight Crew, is composed of the Pilot, Co-Pilot, and Flight Engineer. The Pilot is responsible for the overall operation of the aircraft, while the Co-Pilot assists the Pilot in navigation and other duties. The Flight Engineer monitors the aircraft's systems and assists the Pilot and Co-Pilot with the operation of the aircraft. Together, the Cockpit Crew ensures the safe and efficient operation of the aircraft. The term 'FLYERS' is often used to refer to the Cockpit Crew, as they are the ones who fly the aircraft.
