New Zealand’s busiest airport will begin experimenting with digital tower technology, joining a handful of other airports around the world testing how they might benefit from the system.A prototype digital air traffic control is being trialled at Auckland International Airport. Airways New Zealand, the county’s only air navigation service provider, announced today that it had partnered with technology firm Frequentis to engineer the technology. The demonstration prototype will be used to assess how digital towers could increase aviation safety and extend hours of air services in more regional locations, enhance resilience and improve traffic flows in bad weather.
