dans manages a number of CNS systems with integrated redundancies for resilience purposes. To further ensure business continuity, an asset replacement and enhancement programme is now ongoing at DXB and DWC.
Various radio communication systems and facilities are being replaced or enhanced at both airports, and are scheduled for completion in 2017 Q1. A significant benefit is the prevention of double transmitions – a hazard that has a major safety impact in congested airspace or airports. A new voice communication system is also planned to replace the existing system. It will provide sufficient radio frequencies and a communication network that will more than cater to the additional controller working positions that are envisaged at both airports.
The need to move multiple Code E and F aircraft around the manoeuvring areas of DXB is critical to Dubai Airports’ business plan. However, this is challenged by the positioning of existing runways and taxiways. In response, a CAT-III ILS system was implemented for DXB’s southern runway in 2014.
In 2017 the southern runway ILS system will be upgraded to reduce the existing Localiser sensitive areas and facilitate the movement of departing aircraft across the southern runway.
To further enhance landing navigation capability at Dubai Airports, dans has endorsed deployment of GBAS at both DXB and DWC. This system (based on satellite and ground base transmissions) is not new, but recent technological advances and the availability of more satellites has significantly improved its accuracy and resilience.
- Surveillance – WAM and ADSB
Two PSR/MSSR radar surveillance systems are presently located at DXB and DWC. A third system has been decommissioned and was replaced in July, 2016. Airborn surveillance coverage and resilience is further enhanced through other radar sources (located within the UAE) and integrated with its ATM system. Additionally in Q2, 2017 dans is introducing the latest WAM and ADSB technology at DXB, with the intention of eventually expanding the coverage at DWC.
