Lifting Aviation Off the Ground: Planning the Next Generation Air Transportation System
--------------------------------------------------------------------------------
March 2006

Today\'s national airspace system relies on a fixed structure tied to more than 5,000 ground-based navigation aids. In its place, the authors of a new model—the Next Generation Air Transportation System—envision a world where travelers and shippers set their own arrival and departure times, pilots assume some tasks now handled by controllers, and precision landings occur without control towers or radar. In promoting the new model, Secretary of Transportation Norman Mineta said it heralds \"an exciting future where even the sky may not be the limit.\"
The genesis of the air transportation system transformation was the 2003 Vision 100—Century of Aviation Reauthorization Act. A major impetus for the measure was economics, especially the need to accommodate an expected tripling of demand in the next 20 years, including unmanned vehicles, and increases in single-engine planes and small jets. The primary goals of the next generation system are to improve the level of safety, security, efficiency, quality, and affordability of the National Airspace System and aviation services.

The Act created the Joint Planning & Development Office (JPDO), a partnership of seven agencies, plus the private sector, as the hub of activity (see \"The Cast of the JPDO\"). Amr ElSawy, senior vice president and general manager of the Center for Advanced Aviation System Development (CAASD), describes it as \"a brand new operating model for government. The idea is to have technical alignment, programmatic alignment, and budgetary alignment toward a single mission. I think that is both unprecedented and difficult to do.\"

MITRE as Chief Engineer

At the very center is MITRE, serving in the role of the JPDO chief engineer. Jerry Friedman, a CAASD director, holds the title and leads the effort, but ElSawy says the function is really \"beyond a sole individual’s capacity—it includes the capabilities of the entire company.\"

Friedman is a nine-year veteran of similar privileged roles, most recently as chief architect for the Air Force. He describes the task of planning the Next Generation Air Transportation System as \"unprecedented not only in its scale, but also because it crosses the boundaries of the core mission areas of so many agencies. There really are few if any pathfinders.\"

Given this complexity, he says, the expectation of our sponsors is that we will fully leverage across all of MITRE. \"Whenever I mention that somebody from [MITRE\'s] Air Force Center or the Washington Command, Control, and Communications Center is working on this, or that we\'re consulting with somebody from our Center for Enterprise Modernization, that’s exactly what our customers want to hear,\" says Friedman. \"That’s why they want MITRE.\"

Demonstrating the Future
Security operations stand to gain significant advantage from shared situational awareness. In today\'s aviation environment, the time it takes to share information about a suspicious aircraft—off-course, transponder turned off, or veering into restricted airspace—often precludes any option but interception, a costly proposition (close to $40,000/hour) for a frequent event.

Showing the impact of shared situational awareness was the focus of a multi-agency,
multi-million-dollar, multi-company, multi-system demonstration staged last fall. The Network-Enabled Operations demo linked equipment in 11 laboratories in eight states, different types of control displays—including personal digital assistants (PDAs)—and several agencies.

The first operator to spot the fictitious aircraft straying from its pre-set path could send messages instantly to interested operators in other operating centers and then transmit cueing information for display on other radar systems. They could share a passenger list for checking against the terrorist watch list. In one scenario, the suspicious action stemmed from an avionics problem, which was confirmed by the air marshal using his PDA. No action needed.
