SCOTT SIMON, HOST:
Government's trying to modernize the nation's air traffic control system; with cost overruns, software problems and management concerns, makes some wonder whether the so-called Next Generation system may take another generation to complete.
NPR's Brian Naylor reports.
BRIAN NAYLOR, BYLINE: The radar screens in the nation's aircraft control towers are based on technology dating to the Second World War. Many of the routes airliners fly were laid out at a time pilots followed bonfires for navigation at night. The promise of NextGen, as explained in a video on the Federal Aviation Administration's website, is to bring all that into the 21st century.

UNIDENTIFIED MAN: You will appreciate the increased safety, environmental benefits, and reduced delays as the Next Generation air transportation system is adopted.
NAYLOR: What sounds so wiz-bang in the video isn't really all that different from the satellite-based GPS navigation systems many Americans have in their cars, but adopting that technology to the airline industry has been a challenge. The Transportation Department's inspector general reported that one of the key software components of the system is running more than $300 million over budget, and might not be fully phased in for another five years.
Airlines have been investing in elements of the new system, one in particular which would enable aircraft to land in a more efficient, fuel-saving manner.
Steve Lott is with the Air Transport Association, the airline industry lobbying group.
STEVE LOTT: You know, where you're flying on a plane you can actually feel it where a plane will lose altitude and it will drop, say, 5,000 feet and then it'll stay steady for awhile, at the same altitude. And it'll drop again. It's this stepped landing approach that is not particularly efficient. And using satellite technology, we can have a smoother landing.
NAYLOR: Lott says the airline industry wants the FAA to allow more use of the advanced navigation procedure which many aircraft are now equipped for. The deputy administrator of the FAA, Michael Huerta, told a congressional panel recently the agency is working on making that happen.
MICHAEL HUERTA: In the year ahead, what we really want to do is focus on how can we improve the quality of these procedures, and how can we see the very real benefits associated with reduced fuel consumption, reduced time and corresponding environmental benefits as well.
NAYLOR: But Transportation Secretary Ray LaHood says until Congress approves a long-term bill for the FAA, the NextGen program will remain in a holding pattern.
SECRETARY RAY LAHOOD: We're stuck in mid-air be cause of the fact that Congress wont pass an FAA bill. As soon as they pass a bill we've got a big, bold vision for Next Generation technology.
NAYLOR: The government's share of the NextGen program is estimated to be more than 20 billion dollars. And another big concern of its supporters is coming up with that cash, at the same time the government is desperately looking for ways to cut spending.
