US airports are considering a new way of clearing snow — heating pavement. – Could this be the way for UK airports in the furture?
Workers have traditionally relied on chemicals, plows and sweepers to clear snow on runways and taxiways. But some in the industry are pitching the Federal Aviation Administration to make the new methods — passing electric current under the pavement or circulating warm liquids through pipes or tubes — eligible for the federal funding that airports receive for capital-improvement projects.
In a report that outlines the specifications needed for its grants, the FAA says the heating systems could enhance safety for equipment operators, minimize disruptions caused by heavy snow, provide a greener option or reduce snow-removal time.
Disadvantages include high initial costs and complex installation procedures, the FAA says.
The FAA also advised that heated-pavement systems be limited to locations at the airport where manual and chemical treatments are difficult and operational safety is a factor.
It’s being tested on a limited basis at a few airports, says Chris Oswald of Airports Council International-North America. But airports are generally reluctant to install the systems because they’re concerned about ongoing energy costs, he says. “There isn’t a compelling need for these systems in the industry,” Oswald says. “We don’t believe the case has been demonstrated for the need, and that’s what we want to see.”
The council says the FAA has to be more discriminating on selecting new technology eligible for federal subsidies, given the limited pool of money.
