FAA upgrade takes a toll on residents' sleep

Washington

The US Federal Aviation Administration (FAA) has touted the benefits of its shift to a modern, more sophisticated system for managing air traffic.

NextGen, it says, reduces carbon emissions, speeds departures and will save millions, even billions, in fuel costs. In Washington alone, where new flight patterns were put in place last year, the agency estimates that airlines will cut their annual fuel consumption by 2.5 million gallons.
