The most common-known pilots are those who work for an airline company, flying passengers who are commuting or vacationing. Their primary responsibility is to operate the aircraft, but their day consists of other duties as well. Pilots check the weather and confirm flight plans before departing. They also perform pre-flight inspections and check flight logs prior to departure. During the flight, they are responsible for the safety of all crew and passengers on board. They may often need to make split-second decisions and are in constant contact with the Federal Aviation Administration (FAA) to keep abreast of changes to the flight plan or safety issues.
