  2. Description • ILS is a ground-based navigation system used to provide precision guidance to an aircraft approaching and landing on a runway • It uses a localized transmitter, a glide path transmitter, an outer marker, and the approach lighting system.

  3. Components • The localizer provides lateral guidance. It is a VHF(Very High Frequency) radio transmitter and antenna system. • The glide slope provides vertical guidance. It is a UHF(Ultra High Frequency) radio and transmitter system.

  4. Marker beacons provide information on the distance from the runway. They are low power transmitters. • They radiate \ an elliptical Beam upward From the Ground.

  5. Lighting systems enable the pilot to locate the runway accurately. A transmissometer provides the light necessary for this.

  6. There now are several different alternatives to the ILS including: GPS, WAAS(Wide Area Augmentation System), and LAAS(Local Area Augmentation System).

  7. Conclusion • The ILS is a precise form of navigation that has been a great help to pilots. • With the rise of other navigation systems, precise navigation is now pretty common.
