Heathrow Turns to AI to Cut Gap Between Flights by 20 Seconds

London’s Heathrow airport will test an array of ultra high-definition cameras to help determine more accurately when its runways are clear of planes and cut the gap between flights by as much as 20 seconds.

If successful, the system will initially be deployed when Heathrow’s 285-foot control tower is shrouded in cloud -- a situation that currently compels the airport to rely on radar readings to determine the position of jets. That in turn requires a bigger gap between flights, costing the hub nine landings an hour or 20 percent of the usual total.
