Airways unveils future digital air traffic control tower

Airways New Zealand is demonstrating a prototype digital air traffic control tower at Auckland Airport, it announced today. The air traffic control organisation is assessing how the technology could increase aviation safety, extend the hours of air services in more regional locations, enhance resilience, and improve traffic flows in bad weather.

A digital tower allows air traffic to be directed by controllers in a remote location watching live footage of the airfield from high-definition video cameras. Under the existing system, controllers manage traffic from a tower that overlooks the runway and use multiple systems to gain a complete picture of the airfield.

Airways Chief Operating Officer Pauline Lamb says digital towers are a viable alternative to bricks and mortar air traffic control towers that have the potential to improve safety through greatly improved aircraft tracking ability and enhanced visual images.

“For example, cameras can automatically zoom in and track objects that are fast moving or otherwise hard to see, such as birds which are a serious hazard to aircraft. In low light or bad weather, infrared would provide controllers with heightened visibility,” she says.

Digital towers present controllers with a huge amount of information and panoramic views of an airfield in more detail than is possible to see with the human eye.

This vision is enhanced with surveillance sensors and microphones. Augmented reality overlays mean controllers will be able to see additional flight data collected via radar like aircraft speed, separation between aircraft and airfield information.

"Digital towers are one of the intelligent transport technologies we are looking at to modernise our air traffic network and ensure New Zealand gets the most benefit out of an increasingly complex and busy airspace,” Ms Lamb says.

The most recent estimates suggest that demand for air transport in New Zealand will increase by an average of 4.3% per annum over the next 20 years. And, with the arrival of UAVs, rockets and other new entrants into New Zealand skies, the demand for air traffic management services is increasing.

“In future digital towers could support greater air connectivity, by giving us the option to extend services in areas of New Zealand where the costs of building or servicing a physical tower are currently not cost effective,” she says.

The prototype tower is not being used to manage live traffic. In the first instance Airways is exploring digital towers to see how the technology could be used as a contingency option to back-up to physical towers.

Digital tower technology is gaining a foothold internationally. Systems are currently being tested at Changi and London City Airports, and rolled out across Sweden and Norway.

Airways has partnered with Austrian technology leader Frequentis to engineer the demonstration system.
