London City is not a remote-low-traffic airport. Staffing a remote airport is like having lighthouse keepers. That I understand.
And yet the tower will be closed, and moved off-airport to become a virtual tower.
All those working on the project are very happy apparently, and the press releases (and videos) don't reveal much. I don't get it. The only thing that I saw as a positive, was an augmented reality overlay on the screens that highlights nearby drones.
(...) a critical new safety feature means the cameras will be able to pick out rogue drones near the airport, as well as light the runway at night.
Why would a major airport undergo such change? What problems are being solved?
