Navigation and Instrument Landing Systems

With different functions, the navigation systems provide accurate navigation guidance information during approach and landing.

  • Glide path, GP

  • Localizer, LLZ

  • Distance measuring equipment, DME

  • Doppler VHF Omnidirectional Range, DVOR (VOR)

  • Non-directional radio beacon, NDB

  • Markers and locators

 

Distance measuring equipment, DME, measures the distance between an aircraft and a ground station via radio signals. By pairing the DME with e.g. a VHF omnidirectional range (VOR), a two-dimensional navigation system is obtained and thus an even more precise guidance information.
 

Doppler VHF Omnidirectional Range, DVOR (VOR), is a ground based radio navigation system that assists the aircraft in the approach by sending omnidirectional signals from ground based beacons located at the runways.
 

Instrument Landing Systems, ILS, is a runway approach aid based on two radio beams to provide pilots with precise vertical and horizontal guidance during landing approach.
