The Federal Aviation Administration will implement a software program at 27 domestic airports that is designed to minimize airport taxi delays and all but eliminate the long lines of aircraft that can build up ahead of takeoff, the agency announced jointly with NASA on Tuesday.

Driving the news: The software calculates gate pushback times at busy airports ranging from Washington National Airport to Phoenix, and is designed to make airports more efficient while also minimizing delays. Rollout will begin in early 2022 and take several years, the FAA said.

A four-year test phase of the software conducted at Charlotte Douglas International Airport, which was conducted jointly with NASA, saved more than 275,000 gallons of fuel annually, or the equivalent to the typical fuel burn of a Boeing 737 flying 185 flights between New York and Chicago.

  • It also cut delays by 916 hours, equivalent to shaving 15 minutes of waiting time on a taxiway for more than 3,600 departing flights.
  • The new program will be part of the FAA’s Terminal Flight Data Manager flight merging system that seeks to allow aircraft to both climb and descend at more constant rates, rather than the current stair-climb system used in many parts of the country.

What they're saying: “The future of flight must be more sustainable and environmentally friendly,” said FAA Administrator Steve Dickson in a press release.

  • “If you do the math, the numbers get very big, very fast, and in a good way across these 27 airports, we estimate a savings of more than 7 million gallons of fuel, and the elimination of more than 75,000 tons of co2 emissions,” Dickson told reporters on a press call Tuesday.

Yes, but: The program won’t be implemented overnight, however, as it will be gradually rolled out to airports that also include: Atlanta, Boston, Chicago O’Hare, Dallas-Ft. Worth, Denver, Seattle, Washington Dulles and New York JFK, among others.

The big picture: The FAA is also taking other steps to make airports more efficient, including through the increased use of electric vehicles.

The Federal Aviation Administration has cleared Virgin Galactic to return to spaceflight operations after concluding an investigation into the company's July trip to suborbital space, Virgin Galactic said in a statement Wednesday.

Why it matters: The high-profile flight, carrying billionaire Richard Branson, was seen as a step forward for the company to begin commercial services in the near future.

The startup that wants to disrupt big internet providers

A new startup backed by funding from AOL founder Steve Case and Laurene Powell Jobs wants to break up broadband monopolies across the country.

Why it matters: Internet access has been crucial during the pandemic, but it's not ubiquitous, and it can be both slow and unaffordable in swaths of the country.

Top general: China's hypersonic missile test "very close" to a "Sputnik moment"

Gen. Mark Milley, the chairman of the Joint Chiefs of Staff, warned Wednesday that China's test of a hypersonic missile is "very concerning" and "very close" to the kind of "Sputnik moment" that triggered the Space Race during the Cold War.

Why it matters: The comments by America's top uniformed general underscore the depths of U.S. concerns about China's rapid military expansion and development of advanced weaponry.
