Airplane taxis are not only annoying but also a major source of greenhouse gas emissions.
Buckle up and know your flight is on its way to your destination: All right. Getting stuck in asphalt traffic and waiting for your flight to take off: Not good. Waiting doesn't seem to help the planet either.
Flying is one of the busiest things to do right now. Globally, air transport generated more than 1 billion tons of carbon emissions in 2019, which is more than 2% of total human emissions - more than sea or rail. Aircraft engines also emit nitrogen oxides, soot particles, and water vapor, which also contribute to global warming.
This new program is part of a two-decade effort to modernize the country's air traffic control system. The plane contains 11 bits of real-time data from the airlines — including when the plane actually left the gate and when another plane hit the asphalt — so you can move the plane more precisely and accurately through the airport. This does not mean that the information is complex or new. This means that the players at the airport - the operators, air traffic control, the airlines - have a means of automatic real-time sharing, with fewer phone calls. Finally, the system must remove the paper progress bars that controllers use to manually track flights, and create an all-digital system that, for example, reminds controllers when a particular runway is closed. The system can save a lot of fuel After the Federal Aviation Administration tested a new program with American Airlines at North Carolina's Charlotte Douglas International Airport for four years, it decided to reduce driving time. It saves more than 275,000 gallons of fuel annually, the equivalent of 185 flights between New York and Chicago on a Boeing 737. Be. For travelers, the project reduced delays by about 40 minutes per day. "For Charlotte Airport - one of the world's busiest, including commercial, cargo, military and private - this means 'you can fly more planes in and out of the ground,'" says Healy Gentry, the airport's director of aviation. . "We're making the most of the berth we have." York, Phoenix and San Francisco, starting in 2022. It could take 10 years for the agency to reach another 27.
For a single passenger, the changes may seem incremental, says Pam Whiteley, the FAA's assistant director for the renewal program, but he expects less inconvenience. "The experience of showing up at the gate, the plane isn't there, I'm not sure when the plane will show up - I hope the passenger doesn't feel like that," he says.
