The move is part of the FAA’s net zero emissions goal by 2050.
In an effort to cut emissions, the Federal Aviation Administration announced it is changing the way some planes land at US airports.
Currently, most aircraft that land at airports are stepped-landing, in which the aircraft repeatedly stalls and starts up its engines during landing. According to the agency’s 42 new Optimized Profile Description, or OPD, planes will alternate from cruising down the runway in a smooth, continuous path with the engines set to idle. near no load.
FAA spokesman Matthew Lehner said in an interview with ABC News: “If you just think about what takes more energy, going down stairs or sliding down a slide, that’s basically it. is what planes are doing.”
The move is part of the agency’s work to achieve a net greenhouse gas emissions aviation sector by 2050 – part of the Secretary of Transportation’s US Aviation Climate Action Plan. Pete Buttigieg is announced at United Nations climate change conference previous November.
“There’s less fuel burned as you slide down the airport approach road,” says Lehner. “It also means that with less fuel burning, you get fewer emissions in the air.”
In 2013, FAA and Georgia Institute of Technology researchers found that OPD had cut approximately 41 million pounds of carbon dioxide emissions and 2 million gallons of jet fuel at Los Angeles International Airport in one year, the equivalent of cutting 1,300 flights from Atlanta to Dallas, the FAA said.
The FAA has deployed OPDs at various airports across the country in 2021, including Dallas-Fort Worth International Airport, Miami International Airport, and Florida’s Orlando International Airport. This year, they plan to perform descents at New York’s LaGuardia Airport, Missouri’s Kansas City International Airport, and Omaha, Nebraska’s Eppley Airport. It is also adding additional routes at Orlando International Airport.
In addition to cutting emissions, the agency says passengers may notice a smoother, quieter approach with the engine not revving during deceleration. The continuous landing technique is also quieter for the area around the airport.
