The software is designed to make your flight smoother and help the earth

Must read

Fasten the seat Buckle and know that your flight is on its way to your destination: good. Getting stuck in traffic jam on the tarmac and waiting for your flight to take off: not so good. It turns out that waiting is not good for the planet.

Flying by plane is already one of the most emissions-intensive things you can do.Globally, aviation production Carbon emissions exceeded 1 billion tons in 2019, More than 2% of human-generated emissions-more than any one transportation Or railway. Aircraft engines also emit nitrogen oxides, soot particles and water vapor, which also contribute to global warming.

Take-off and landing are usually only a small part of the flight, but Account for a quarter of its emissions, According to NASA. Unnecessary aircraft stops during this process will increase fuel consumption. If the plane can enter and exit the airport smoothly, it will be better for everyone (including passengers).

Hamsa Balakrishnan, a professor of aerospace at MIT who studies airport operations, said this is because aircraft engines are designed to operate in the air. When airplanes wait at the gate, they rely on auxiliary power systems to keep essential items running. But once the aircraft is pushed back, it will start to run the engine and burn fuel. Balakrishnan said that being idle at the airport can also damage the local air quality-people live and work near the airport, not in the middle of the sky.Also very noisy

Now, the Federal Aviation Administration and NASA have created a system to smoothly take off and land, eliminating delays and unnecessary emissions in the process. Real rocket scientists are involved-the system is derived from NASA’s work to help spacecraft establish a stable orbit in space.

Today, most airports create take-off queues based on the time the aircraft is pushed back from the gate. This can cause traffic jams on the tarmac and overload of runways that are idle while the aircraft is waiting for takeoff. In addition, air traffic controllers do not always have a good understanding of how long it takes for an aircraft to taxi and lift off. In fact, although the FAA does obtain the schedule for each airline, the controller does not know exactly when the flight will take off until it reaches a specific part of the tarmac. They deal with this unpredictability by establishing buffer zones and adding extra time everywhere to ensure the smooth operation of the entire system. Therefore, “there are many inherent inefficiencies,” said Balakrishnan, a professor at the Massachusetts Institute of Technology.

For passengers, inefficiency is like waiting for a plane to land 30 minutes before boarding, or being tied to an uncomfortable seat while waiting in line for takeoff. For airlines, inefficiency is like burning unnecessary fuel and discharging unnecessary emissions into the air.

The new software is part of two decades of efforts to modernize the country’s air traffic control system. It combines 11 real-time data from airlines—including when one plane actually leaves the gate and when another plane actually hits the tarmac—to more accurately schedule the movement of planes in and out of the airport. It’s not that the information is so complicated or so new. This is where the participants in the airport-operators, air traffic control, airlines-have a way to automatically share it in real time with fewer phone calls.Ultimately, the system should kill Paper progress bar The controller is used to manually track flights and create a fully digital system, for example, to alert the controller when a runway is closed.

The system can save a lot of fuel. After four years of testing the new software with American Airlines at Charlotte Douglas International Airport in North Carolina, the FAA concluded that the reduced taxi time saved more than 275,000 gallons of fuel each year, equivalent to Take a flight 185 between New York and Chicago. Boeing 737. Carbon emissions are reduced by more than 2,900 tons per year, which is about the same as emissions from 15 coal-saving rail cars. For passengers, the project reduced delays by nearly 40 minutes per day. Charlotte Airport is one of the busiest airports in the world, including commercial, cargo, military and private flights, which means “you can let more planes take off and take off,” said Haley Gentry, the airport’s aviation director. “We We are making the most of the sidewalks we have.”
