Airline pilots fly passengers and/or cargo on long or short-haul flights for leisure, business or commercial purposes.
The aircraft is typically operated by two pilots; one will be the captain who is the pilot in command, while the other will be the supporting first officer. The pilots will usually take turns to fly the plane to avoid fatigue, with one operating the controls while the other speaks to air traffic control and completes the paperwork. In some instances, such as long-haul flights, there may be three or four pilots on board so that the necessary breaks from flying can be taken.
Prior to the flight, pilots check flight plans, ensure that the aircraft's controls are operating efficiently and calculate the required fuel for the flight. They are also responsible for checking the weather conditions and briefing cabin crew.
