Aircraft Navigation

  • Ever wondered how the pilots know which way they are going? This article takes a look at how commercial aircraft are navigated over thousands of miles, seamlessly reaching their destination with pinpoint.

  • The common Nav system used on aircraft today is GPS. At the start of the flight, the pilots load a predetermined route into the Flight Management System or Computer (FMS / FMC). This imposes the route of the flight onto a moving map which the pilots can monitor on their screens throughout the flight. The pilots can see other things around their flight path on their screens, like other airports, other aircraft, high terrain, and bad weather.
  • Navigation of Aircraft is achieved through the Flight Management System (FMS)
  • FMS provides map displays, traffic, and weather overlays of data, contains VOR/DME/localizer/glideslope receivers, and can compute fuel usage in addition to the navigation route information.
  • You can feed information into the system as well. The controls allow the pilot to enter information and program the avionics to accomplish the desired operations or tasks.

  • The FMS is constantly updated with aircraft position by reference to available navigation aids such as GPS.
