Last month, the Intelligent Approach User Group – the world’s Time Based Separation trailblazers – met at Swanwick to share their experiences.

You’re on the flight deck, sitting on stand and ready to start engines. You call to the tower to request permission to depart, but what if the clearance you get back doesn’t come from a human air traffic controller, but a computer?

It’s now more than a year since London City Airport successfully transitioned to a digital tower and began controlling flights from a brand-new remote-control centre, based in Swanwick.

Now, instead of sitting in a physical tower based at London City Airport, a dedicated team of controllers manage the runway through sixteen high-definition cameras and sensors mounted on a mast, capturing a 360-degree view of the City Airport airfield.
