We need 21st century air traffic control

Commentary: Gary Kelly is the chairman of the board, president and CEO of Southwest Airlines.

It's been a tough decade for the U.S. airline industry. Over the past ten years, total financial losses have risen to more than $50 billion. Fuel costs are 4.5 times higher. And, an obsolete air traffic control system exists that contributes to congestion and delays. It's not only been a tough decade -- it's been a lost decade.

Once again, escalating fuel prices are having a devastating effect on the airline industry. From the end of 2009 to the end of 2010, the price of jet fuel rose 44 cents per gallon. And, from the end of 2010 to the week ending April 21, the price of jet fuel rose 74 cents per gallon. To put things in perspective, just a penny increase in a gallon of jet fuel costs U.S. airlines $175 million annually.

The airline industry, both individually and collectively, has been focused on reducing our dependence on petroleum-derived jet fuel. Our efforts to conserve fuel have focused on three key areas:

• Modernizing our nation's air traffic control system, including private investments in fuel-efficient technologies;
• Developing, producing and acquiring the most advanced aircraft engines and airframes; and
• Developing, certifying, and eventually producing commercially viable alternative jet fuels.

Step one must be to develop and deliver a much more direct and efficient satellite-based air traffic control system. The FAA has had a plan called "NextGen" to transform today's antiquated ground-based system to a 21st century satellite-based system.

However, the federal government must do more to leverage the technological investments already made by the airline industry so NextGen's benefits -- including greatly improved fuel consumption and reduced emissions -- can be realized much more quickly.

It's not an exaggeration to say that today's air traffic control system is using 1950's technology and flight paths to route our aircraft during a time when most drivers on the highway are following direct routes guided by their GPS systems.

Today's antiquated, ground-based systems add flight time because they do not route aircraft in a direct, linear fashion. Further, because today's technology does not precisely pinpoint an aircraft's position in space, greater separation must be factored into flight patterns.

Utilizing satellite-based systems, the FAA and airlines should be able to route flights more efficiently, precisely, and directly, thereby reducing fuel consumption, as well as flight miles, flight times, congestion, and delays.

Additionally, a satellite-based system would:

• Make a safe system safer and more efficient because everyone shares the same precise view of aircraft in their vicinity;
• Improve airline and airport operations because of greater scheduling and operating reliability;
• Increase efficiency and reduce emissions;
• And, enable the airlines to compete more effectively in the global marketplace.

The fuel savings projected from full NextGen implementation are significant and range from 6 to 15 %. Even a 6% fleetwide reduction in fuel burn results in 1.16 billion gallons in fuel savings and nearly 11 million metric tons (24 billion pounds) of carbon dioxide savings.

Southwest (LUV, Fortune 500) is the first airline to commit to spending millions of dollars to outfit its entire fleet with a GPS-based, NextGen technology called "Required Navigation Performance" (RNP). To date, we have committed to investing more than $175 million dollars over the next several years to install GPS in our 550 Boeing 737 aircraft and train our 6,000-plus pilots in RNP.

But the airlines cannot reach NextGen alone. The FAA, in coordination with the aviation community, must focus its limited resources to design and implement GPS-based flight paths that will result in measurable reductions in fuel consumption and emissions.

In other words, it does no good to use new technology to fly the same old routes more precisely. We must have new flight procedures approved by the FAA to leverage the tremendous potential of NextGen technologies.

Although it's been discussed since the 1970s, Southwest, along with the entire domestic airline industry, is ready for NextGen now.
