London City Airport launches fully digital air traffic control tower

Published on : Friday, April 30, 2021

London City Airport has become the first major international airport in the world to be fully controlled by a remote digital air traffic control tower. The announcement follows intensive testing and live trials of the revolutionary technology during lockdown. All flights on the summer schedule are being guided to land by air traffic controllers based 115-kilometres away at Nats’ air traffic control centre in Swanwick, Hampshire.


Controllers will be using an ‘enhanced reality’ view supplied by a state-of-the-art 50 metres digital control tower. The technology marks a step-change in global air traffic management and will help the airport meet an expected surge in demand for flying during the summer season as COVID-19 restrictions are eased. The multi-million-pound investment in the proven remote digital technology marks a major milestone in City Airport’s investment in its future, following the completion of new aircraft stands and a full-length parallel taxiway which became operational in December.


The technology was pioneered by Saab Digital Air Traffic Solutions, which has successfully tried and tested the system at Ornskoldsvik and Sundsvall airports in Sweden. Sixteen high-definition cameras and sensors mounted on the mast capture a 360-degree view of the airfield. This is relayed through super-fast fibre connections to a new control room in Nat’s air traffic control centre in Swanwick. A dedicated team of controllers will use the live footage, an audio feed from the airfield and radar information to instruct aircraft movements in and out of the airport.


The live feed, transmitted through independent secure fibre networks, is displayed on 14 HD screens in the Swanwick control room to provide a panoramic moving image. This can be overlaid with digital data to provide an ‘enhanced reality’ view. Information such as call signs, altitude and speed of all aircraft approaching and leaving the airport, weather readings and the ability to track moving objects can all be included in this single visual display. Pan-tilt-zoom cameras can magnify images up to 30 times for close inspection.


Alison FitzGerald, Chief Operating Officer, London City Airport said in a statement that they are immensely proud to become the first major international airport to adopt the pioneering technology. The investment in smart infrastructure will help meet future growth in passenger demand, improve air traffic management and give an enhanced capability as aviation bounces back from the pandemic. She mentioned that it is also a demonstration of the commitment to innovation in the UK aviation sector and to being at the forefront of defining the future of flight. She shared that since going operational at the end of January; the technology has worked really well and is ready for the expected increase in demand for flights as Brits book their well-deserved summer getaways.
