Toronto Pearson International Airport (YYZ) has introduced new landing procedures in order to reduce greenhouse gas emissions and noise caused by descending aircraft.

Nav Canada, which runs the country's air navigation system, has unrolled a new practice that allows aircraft to shorten their flight paths and flying times, reduce fuel burn, and increase the use of quieter descent operations.

Leveraging satellite-based positioning and modern flight management systems, planes are now able to arrive simultaneously on parallel runways on more direct and efficient routes, the organization said in a statement.

“As Canada’s air navigation service provider, our goal is to ensure aircraft transit to their destination on the safest and most efficient path possible, while also respecting local communities and reducing the overall impact on the environment,” said Blake Cushnie, program director at NAV CANADA. “The EoR project at Toronto Pearson is designed to achieve just that and we believe this concept will eventually become the new normal at other major international airports globally. We are pleased to be at the forefront of this evolution, building on EoR’s first successful deployment at Calgary International Airport and now at one of the world’s busiest airports.”

Until now, aircraft that landed simultaneously on parallel runways were separated by three nautical miles laterally or 1,000 feet vertically until they were lined up with the runway and established on final.

As a result, some aircraft were required to fly at a low altitude or a longer trajectory to maintain their separation, Nav Canada says.

Planes approaching Pearson from the south will now be able to fly up to 1,000 feet higher than before, which Nav Canada says will also reduce noise over some communities.

The changes will result in shorter routes and lowered fuel consumption, helping to decrease the aviation industry’s impact on the environment, the organization says.

“Over the next 10 years, [the new practice] at Toronto Pearson is estimated to reduce greenhouse gas emissions by 178 million kilograms,” Nav Canada said.

Toronto Pearson is the second airport in Canada to implement the new process, which is called the “Established on RNP-AR' ICAO standard.”

The procedure was first introduced at Calgary International Airport in 2018.

Several airlines in Canada have supported Nav Canada’s modernization efforts, the organization said, including WestJet and Air Canada.

Currently, all of WestJet’s fleet and the majority of Air Canada’s fleet of aircraft are equipped for RNP-AR.
