The term Fly-by-Wire is associated with aeronautics, especially the automatic computer controlled operation of an aircraft.

  Instead of conventional mechanical controls, operated manually by the pilot, the Fly-Wire-System of modern technology uses computers to control all the flight operations of an aircraft.

  The system is extremely reliable, accurate and free from human errors. In this technology electrical, electronic and computer systems completely replace conventional, mechanical systems required for, like turning the rudder or wing flaps of an aircraft.

  However, hydraulic or pneumatic systems required for like applying brakes to wheels, are only partially replaced. The most important feature of this high-tech system is that the computers perform all the calculations connected with the flight of an aircraft and conduct it in safe and fuel-efficient manner.

  They also issue instructions to update and correct the speed and altitude of the aircraft to obtain the maximum mileage.

  If by any chance, any instrument or part of the aircraft malfunctions or fails, the computers issue warning signals to the crew to take corrective action.

  And above all, if a pilot makes a mistake during a flight, the computers issue him a warning to rectify his mistake during a flight, the computers issue him a warning to rectify his mistake or lock the relevant control at the safety limit. To date, the only aircraft equipped with this technology is the Airbus-320.
