What does NAS stand for?

These vehicles will present unique challenges for the FAA with their high-speed flight through the national airspace system during their ascent and descent from space.

Balancing all of these issues will be a challenge, but is essential to FAA's ability to transform and operate the national airspace system safely and efficiently.

Sep 3, 2007 US Government Accountability Office issued a report on very light jets indicating that there is little consensus on their impact on the National Airspace System or on US FAA's costs and Trust Fund revenues but that "most experts" said Very Light Jets - VLJs "will likely have little impact on safety due to FAA's certification procedures for aircraft, pilots and maintenance.

The HOCSR upgrade has been a very solid success for the FAA and is another important step in the agency's efforts to modernize the National Airspace System infrastructure," said Sue Corcoran, vice president for North American Programs at Lockheed Martin Air Traffic Management.

The FAA is planning to re-compete its current technical assistance contract supporting the management, engineering, development, acquisition, and implementation of a particular group of surveillance systems for use in the national Airspace System.

We are pleased to have been awarded the opportunity to continue to serve the FAA at the world's premier aviation research and development facility, which is dedicated to enhancing the National Airspace System.

GE Aviation and the FAA have entered into a cooperative research and development agreement (CRDA) to assess ways to integrate unmanned aerial vehicles (UAVs) into the National Airspace System (NAS) -- including using next generation trajectory-based operations.

The Federal Aviation Administration (FAA), together with the National Aeronautics and Space Administration (NASA), the Environmental Protection Agency (EPA), and others, is working to increase the efficiency, safety, and capacity of the national airspace system and at the same time reduce aviation emissions, in part, by transforming the current air traffic control system to the Next Generation Air Transportation System (NextGen).
