The navigation system includes VHF omnidirectional range ( VOR ), distance measuring equipment ( DME ), automatic direction finder ( ADF ), radar altimeter, Global Positioning System ( GPS ), air data computer, and a flight management system.

Some types of navaids, such as non-directional beacons and Distance Measuring Equipment, do not operate on these frequencies; in the case of NDBs, the low frequency and medium frequency bands are used between 190 415 kHz and 510 535 kHz.

In addition to developments in radar, Bowen also undertook two other research activities : the pulse method of acceleration of elementary particles; and air navigation resulted in the Distance Measuring Equipment ( DME ) that was ultimately adopted by many civil aircraft.

The U . S .-made dlrs 2.3 million-worth advanced equipment _ ILS ( Instrumental Landing System ), VOR ( Very high frequency Omni directional Radio range ) and DME ( Distance Measuring Equipment ) _ improves landing conditions even at lower visibility.

The crew decided to fly the instrument landing system ( ILS ); however, the vertical guidance system was inoperative, so they were forced to fly with only the lateral guidance as the first officer monitored the airport's distance measuring equipment ( DME ).

As a result, despite the fact that the aircraft was cleared for a VOR / DME ( VHF omnidirectional range / Distance Measuring Equipment ) approach, it was an ILS / DME ( Instrument Landing System / Distance Measuring Equipment ) that was initiated.

The lack of ground-based navigation aids at Kokoda Airport meant that the only potential navigation assistance for the crew during their approach to Kokoda was from the GPS, or via the ground-based non-directional beacon / distance measuring equipment ( NDB / DME ) located at Girua.

The air station is equipped with state-of-the-art airport surveillance radar ( ASR ), precision approach path indicator ( PAPI ), Doppler very high frequency omnidirectional radio range ( DVOR ) distance measuring equipment ( DME ) and nondirectional beacon ( NDB ), as navigational aids.
