The aircrew of a Jetstar Airways Boeing 787

Aircrew, also called flight crew, are personnel who operate an aircraft while in flight. The composition of a flight's crew depends on the type of aircraft, plus the duration and purpose of the flight.

Commercial aviation

Flight deck positions

In commercial aviation, the aircrew are called its 'Flight Crew'. Some flight crew position names were originally derived from nautical terms, and also indicated a rank, or command structure similar to that on an ocean-going vessel, quickly allowing for executive decision making during normal operations or emergency situations. Historical flightdeck positions include:

  • Captain, the pilot designated as the Pilot-In-Command (PIC),[1][2] and the highest-ranking member or members of a flight crew.
  • First Officer (FO, also called a co-pilot), another pilot who is not the pilot-in-command, and is normally seated to the right of the captain. (On helicopters, an FO is normally seated to the left of the captain, who occupies the right hand seat).[1][2]
  • Second Officer (SO), a person lower in rank to the First Officer, and who typically performs selected duties and also acts as a relief pilot. The rank of Second Officer was traditionally a Flight Engineer, who was often the person who handled the engine controls. In the 21st century second officers on some airlines are pilots who act as "cruise relief" on long haul flights.[2][3][4]
  • Third Officer (TO), a person lower in rank to a Second Officer, and who typically performs selected duties and can also act as a relief pilot. Largely redundant in the present day.[3]
  • 'Relief Crew' members in the present day are fully licensed and trained Captains and First Officers who accompany long-haul airline flights, and who relieve the primary pilots during designated portions of the flight to provide them with rest or sleep breaks (some large wide-body airliners are equipped with special pilot sleeper berths, but more typically reserved seats in the section closest to the flight deck, or cockpit, are used for the relief crew). The number of relief crew members assigned to a flight depends in part on the length of the flight and the official air regulations the airline operates under.[2][3]
  • Flight Engineer (FE), a position originally called an 'Air Mechanic'. On older aircraft, typically between the late-1920s and the 1970s, the Flight Engineer was the crew member responsible for engines, systems and fuel management. As aircraft became increasingly sophisticated and automated, this function has been mostly assumed by the primary pilots (Captain and FO), resulting in a continued downsizing in the number of aircrew positions on commercial flights. The Flight Engineer's position is commonly staffed as a Second Officer. Flight engineers can still be found in the present day (in greatly diminished numbers), used on airline or air freight operations still flying such older aircraft. The position is typically crewed by a dual-licensed Pilot-Flight Engineer in the present day.[3][5][6][7]

  • Radio Operator (archaic). A position on much older aircraft, typically between the mid-1910s and the 1940s, where a separate crew member was often responsible for handling telegraphic and voice radio communications between the aircraft and ground stations. As radio sets became increasingly sophisticated and easier to operate, the function was taken over directly by a FO or SO, and still later by the pilot-in-command and co-pilot, making the radio operator's position redundant.[3][9][10]

Cabin positions

Aircraft cabin crew members can consist of:

  • Purser or In-flight Service Manager, is responsible for the cabin crew as a team leader.
  • Flight attendant or Cabin Crew, is the crew member responsible for the safety of passengers. Historically during the early era of commercial aviation, the position was staffed by young 'cabin boys' who assisted passengers.[11] Cabin boys were replaced by female nurses, originally called 'stewardesses'. The medical background requirement for the flight attendant position was later dropped.[11]
  • Flight medic, is a specialized paramedic employed on air ambulance aircraft or flights.
  • Loadmaster, is a crew member on a cargo aircraft responsible for loading freight and personnel, and for calculating the aircraft's weight and balance prior to flight, which must be within the aircraft manufacturer's prescribed limits, for safe flight. On non-cargo aircraft, weight and balance tasks are performed by the flight crew.


USAF, RAF and RAAF aircrew and maintenance personnel with their C-17s

From the start of military aviation, additional crew members have flown on military aircraft. Over time these duties have expanded:

  • Pilot
  • Co-pilot
  • Air gunner, crew member responsible for the operation of defensive weapons, for example gun turrets. Specific positions include nose gunner, door gunner and tail gunner
  • Bombardier or Bomb Aimer is a crew member for the release of ordnance particularly bombs.
  • Boom operator, in the USAF the crew member on tanker aircraft responsible for operating the flying boom and the transfer of fuel.
  • Combat systems officer
  • Crew chief, an enlisted aircraft mechanic responsible for the maintenance and preparation of the aircraft.
  • Flight engineer, a crew member responsible for engines, systems and fuel management.
  • Flight officer
  • Flight surgeon, not involved in the operation of the aircraft but is considered by some militaries to be aircrew.
  • Loadmaster, crew member responsible for loading freight and personnel and the weight and balance of the aircraft.
  • Navigator, a crew member responsible for air navigation. Still actively trained and licensed in some present day militaries, as electronic navigation aids can not be assumed to be operational during warfare.
  • Air observer
  • Rescue swimmer on air-sea rescue aircraft
  • Signaller or radio operator, crew member responsible for the operation of the aircraft communications systems.
  • Tactical coordinator
  • Weapon systems officer or "Weapon Systems Operator"
