FARNBOROUGH, England—UK air navigation service provider NATS plans to stage a major contrail management trial later this year, as attempts to limit or reduce the warming effects of contrails intensify.
Non-CO2 climate-warming phenomena like contrails have come under increasing scrutiny in recent years as potentially having as great an effect on the climate as aircraft exhaust emissions.
“We’ve been working with government and a collection of organizations like Google, the [UK] Met Office and Cambridge University, at the behest of the government, to run a large-scale contrail management trial over the North Atlantic this winter,” NATS’ sustainability director, Ian Jopson told ATW at the air show.
“We’re waiting for ministerial sign-off [for the trial],” Jopson said. “We’ve been working with airlines like EasyJet on individual contrail avoidance flights. It’s quite easy to do a single flight, but in a network that handles 2.5 million flights a year, it’s more difficult.” Noting that the air traffic control system operates at all hours, “It’s a bit like trying to change the tires on a Formula 1 car while it’s moving,” Jopson said.
