Through the use of new Area Navigation (RNAV) approach procedures, the NextGen programme allows for a more efficient and environmentally friendly satellite-based air traffic control (ATC ) system.
US transportation secretary Ray LaHood said that these new procedures in Portland are the building blocks of NextGen.
"NextGen initiatives underway in major regions across the country are helping deliver more on-time flights for consumers, reducing fuel consumption for airlines and creating an even safer aviation system," LaHood said.
Using RNAV technology, flights landing at Portland Airport will cut fuel consumption, noise and emissions.
FAA acting administrator Michael Huerta said that these procedures will continue to improve operational safety and efficiency at Portland International Airport, while improving air quality around the region.
RNAV procedures are also aimed at maximising the efficiency of the ATC system and will allow aircraft to fly more accurate and predictable routes, allowing efficient use of airspace, while reducing pilot-controller communications.
The design phase of new RNAV approaches, which were aimed at connecting future arrival routes from the north, east and south, involved FAA along with the PDX C itizens Noise Advisory C ommittee, the Port of Portland and airlines.
