Communications, navigation and surveillance services are provided all over the Vilnius Flight Information Region.
Flight safety in this region is ensured by the currently operating communications, navigation and surveillance facilities, meeting the international civil aviation standards. Maintenance of the facilities is performed by highly-qualified specialists. The enterprise annually allocates considerable funds for their skills development and it means investment not only into successful solution of everyday issues, but also investment into the future.
Navigation systems are designed to provide crew members with the precise information on the position of aircraft in the airspace.
For the purpose of providing air navigation services the following radio navigation facilities are used:
|
|
VHF Doppler omnidirectional radio beacons (DVOR) and VHF omnidirectional beacons (VOR); |
|
|
Distance measurement equipment (DME); |
|
|
VHF automatic direction finders (ADF); |
|
|
Nondirectional radio beacons (NDB) and etc. |
DVOR/DME or VOR/DME complexes, operating in the Vilnius Flight Information Region (FIR) form a special navigation data field, providing crew members with the precise information on the position of an aircraft in the airspace.
Instrument landing systems (ILS) provide information on the position of an aircraft with respect to a runway. Lithuanian airports are equipped with ILS of ICAO category I, permitting precision approach with a decision height of 60 m and a visibility of 800 m. Landing direction in respect of a runway is strictly observed. Radar surveillance systems provide air traffic controllers with the precise information (with an error of 300 metres) on the position of aircraft in a radar control zone. Alongside with precise coordinates, additional messages on the flight altitude, speed, flight profile, route and other relevant information is displayed.
Three radars in Vilnius, Kaunas and Klaipėda are connected into the air traffic control system and provide primary and secondary radar information. Advanced communications systems ensure continuous information exchange with crew members and air traffic controllers in all phases of a flight as well as uninterrupted data sharing with the neighbouring centres.
