NAV PORTUGAL HAS SEVERAL TYPES OF RADIO-AIDS:


- VOR (VHF Omnidirectional Radio Range), which gives the pilot information on the radial area in which he is flying;

- DME (Distance Measuring Equipment), which gives the distance between the aircraft and the radio-aid;

- NDB (Non-directional Radio Beacon), which provides the position of the aircraft with respect to the radio-aid;

- ILS (Instrument Landing System), situated in airports and which allows landing with the help of ground guidance.  This is an important aid tool in conditions of Low visibility. 



RADIO-AID FUNCTIONS

The radio-aid stations provide the aircraft with a set of information which allows them to fly on the established routes, locate aerodromes and other significant points and to fulfil the proper approach procedures.
