Thales won a contract by the Ministry of Transport & Communications of the Sultanate of Oman to supply, install, and commission 10 instrument landing systems (ILS)/Distance Measuring Equipment (DME) systems and six Doppler-VOR (DVOR) VHF Omnidirectional Radio Range/DME systems to Muscat and Salalah international airports, as well as to five regional airports located in Sohar, Al Duqm, Adam, Ras Al Hadd, and Haima.The contract will modernize Oman's current navigation surveillance capabilities, contributing towards a considerable increase in flight safety. The recent air traffic growth in the Persian Gulf region has led to a crucial need for modernization of the Sultanate of Oman’s transport infrastructure, along with Oman's ambition to increase tourism."This contract further increases our footprint in the region and is an acknowledgement of our capabilities and expertise in navigation surveillance systems," says Olivier Badard, president, Thales Middle East and Western Asia. "Oman’s Ministry of Transportation has chosen Thales's latest generation equipment to replace its existing navigation aids, and enabling them to improve landing capability and increase flight safety." The new navigation systems will be deployed nationwide in three packages -- A, B, and C -- with these divided into nine phases. Packages A and B and related phases, which will begin immediately, include delivery, installation, and commissioning of six ILS and two DVOR systems for Muscat and Salalah International Airports. Package C will include delivery, installation, and commissioning of four ILS and four DVOR navigation systems for Sohar, Al Duqm, Adam, Ras Al Hadd, and Haima regional airports.The DME system provides pilots with distance information between the aircraft and the location of the DME ground equipment. The system is used for both en-route and terminal area guidance.DVOR VHF Omnidirectional Radio Range system is suited to operation under demanding conditions and terrain. The system uses micro-processor control to provide accuracy.
