United States – Washington wants to limit the wait on the tarmac to reduce pollution


Software developed by NASA and the FAA will be deployed in several American airports. Purpose: to calculate the right moment for the plane to leave the boarding gate.

This image, showing several planes queuing on the tarmac before take-off, should soon be remembered thanks to new software developed by NASA and the FAA that will be deployed at 27 US airports.


Several major American airports will soon use software to calculate when an aircraft must leave the boarding gate to prevent it from waiting on the tarmac before take off with the engines on, and thus limit emissions but also delays. .

Developed by NASA and the FAA, the American agencies in charge of space and aviation, this air traffic management software must be deployed in 27 airports, details a communicated mardi.

According to experiments already carried out at the airport in Charlotte, North Carolina, the software has reduced the consumption of kerosene by more than a million liters per year, the equivalent of 185 flights between New York and Chicago. with a Boeing 737.

Less delays too

The software also reduced delays by 916 hours over four years, the equivalent of 15 minutes less waiting time on the tarmac for more than 3,600 flights.

“Currently, air traffic controllers have the company’s schedule but only find out when planes are ready to go when they join the line (aircraft ready to take off) on the tarmac and communicate with the control tower” FAA boss Steve Dickson explained during a presentation.

“Now, we will have more visibility on the data of the companies and we will be able to predict the departure time much more easily, which will allow us to better manage the entire system and avoid bottlenecks on the ground, ”he added.

A sector with a heavy carbon footprint

Reducing aircraft taxiing time is one tool among others used by the aviation sector, responsible for 2% to 3% of greenhouse gas emissions responsible for global warming, to reduce its carbon footprint.

On the ground, companies can, for example, run aircraft with electric motors rather than jet engines, with a single engine running, or use a tractor to which the aircraft is docked to reach the take-off runway.
