GPS-Aided Test Flight Lowers Emissions by 35 Percent in Alaska Airlines “Greener Skies” Project

GPS-Aided Test Flight Lowers Emissions by 35 Percent in Alaska Airlines “Greener Skies” Project

Alaska Air graphic

Alaska Airlines demonstrated next-generation GPS-aided flight procedures last week (July 23) during a test flight over Puget Sound, Washington, that burned less fuel and reduced emissions by 35 percent compared to a conventional landing.

The flight was part of Alaska Air Group’s “Greener Skies” project at Seattle-Tacoma International Airport (Sea-Tac) focused on using satellite-based guidance technology to fly more efficient landing procedures that will reduce environmental impacts in the region.
