  • [narrator] Air travel has changed a great deal since the 1950s.

  • Jetliner technology has improved dramatically.

  • Many more cities are connected, and the number of flights per day has skyrocketed.

  • The air traffic management system, however, is essentially the same,

  • and while the air traffic control system remains extremely safe,

  • it is unnecessarily inefficient and a source of noise and delays.

  • That's why Boeing has developed a new solution

  • that could save billions of gallons of fuel every year,

  • reduce noise around airports, and help ensure more on-time arrivals.

  • It's called "Tailored Arrivals."

  • Depending on the aircraft type,

  • [Suzanne Hawkins, Systems Engineer, Boeing Research and Technology]

  • our trials have shown that tailored arrivals can save

  • between 400 to 800 pounds of fuel per arrival.

  • [narrator] That translates into 58-116 gallons for every landing.

  • With more than 30,000 flights everyday in the United States alone,

  • the potential savings per year are enormous.

  • [Hawkins] As an analogy, tailored arrivals would be like taking a ramp to get down to the ground

  • rather than taking the stairs and slowly descending in steps.

  • Air traffic controllers usually direct the aircraft down through several altitude levels

  • in a stairstep approach to the runway.

  • This requires pilots to power up engines after reaching each successive step.

  • With a tailored arrival, an aircraft is guided by computers to smoothly glide from top of descent

  • directly to the airport runway for landing.

  • This allows the aircraft to descend continuously at low engine power.

  • [Hawkins] The computers on the airplane know the most efficient path to take,

  • so when we can let the airplane do that, we can end up saving fuel.

  • [narrator] When you cut fuel use, you also cut greenhouse gases.

  • If the tailored arrival system were fully implemented around the globe,

  • it could reduce CO2 emissions by billions of tons per year.

  • That's like taking hundreds of thousands of cars off the road.

  • [Hawkins] In addition to fuel savings and reducing carbon emissions,

  • tailored arrivals also reduce workload to the pilot and controller,

  • and they reduce the flight duration, so that can help improve on-time arrivals.

  • [narrator] The world has been using an air traffic control system designed in the 1950s.

  • It's been a remarkably effective system over the decades,

  • but it wasn't designed to save fuel, reduce noise, and help ensure more on-time arrivals

  • at today's busier airports.

  • That's our challenge now, a challenge being met with tailored arrivals.
