Levels Remain Constant Even As Airport Gets Busier

Efforts to reduce jet engine noise have resulted in real benefits for those living near Wyoming's Jackson Hole Airport. Officials there say noise levels have held steady over the years... even as more passengers arrive and depart the airport.

The reason? Quieter airplane engines, and voluntary programs that keep planes away from residential areas.

Assistant airport director Jeanne Kirkpatrick says the airport has seen an increase in the number of commercial aircraft flying with engines that meet or exceed the Stage III standard.

Airport director Ray Bishop told the Jackson Hole News & Guide the airport’s 2006 annual noise report “good news for everybody.”

“All of the noise at the airport is well below our established goal and the enplanements have gone up dramatically,” said Bishop. “There are more people on quieter and less frequent airplanes. If you look at any airport throughout the country, the Stage III engines are lowering the noise footprint dramatically. It’s been a quiet revolution, so to speak.”

Airport officials add Jackson Hole is meeting both its FAA-required noise limits, as well as requirements for nearby Grand Teton National Park. Noise measurements are taken at a variety of areas within the park.

The airport also encourages pilots to arrive and depart the airport's south end whenever possible, as well as other voluntary noise-abatement procedures designed to avoid overflying residential areas.

“We have a volunteer program,” said Bishop. “At the end of the day, it’s up to the pilot. He has the safety right to say ‘no.’”

Some airlines have been more resistant to the voluntary guidelines than others, says Bishop.

“United Airlines has been more reluctant to turn than other airlines,” said Bishop. “But, we’re working on that. We’re trying to be the best neighbor we know how to be.”

Noise reduction methods aren't limited to engine guidelines or designated flight routes, however. Bishop says the airport also plans to plant about 200 spruce trees along the airport's perimeter, to muffle noise even further.
