FAA reconsiders rise in airport noise over parts of south Minneapolis
3. CALL SENATOR AMY KLOBUCHAR 12/8
Amy sits on the Senate Aviation Subcommittee.
The Metropolitan Airports Commission (MAC) will be hosting a noise information public open house for members of the community who are interested in learning about aircraft noise measurements and metrics, the MSP Noise Oversight Committee, historical aircraft arrival and departure data, and other MAC Noise Program functions.
The open house will be held on December 8, 2011 from 5:30-8 p.m. at the at the MAC General Offices located at 6040 28th Avenue South, Minneapolis. For more information please call 612-725-6455.

A top federal aviation official at Minneapolis-St. Paul International airport said Wednesday he’ll investigate whether factors other than a change in takeoff procedures contributed to increased noise over parts of south Minneapolis.
“I tend to agree … that it can’t be just one thing that is doing what people are experiencing,” Carl Rydeen, assistant air traffic manager at MSP, told an airport noise panel. “That’s part of the issue that we are reviewing.”
His comments came in response to more questions from Minneapolis officials and homeowners about increased noise over some neighborhoods in the past year.
The Metropolitan Airports Commission and the Federal Aviation Administration in September attributed additional noise to a decision to route more departures over the neighborhoods as a safety measure. The change reduced the potential for planes to cross flight paths and began after a near-collision between a commercial jetliner and a cargo plane in September 2010. But City Council Member John Quincy expressed skepticism Wednesday that the change alone caused “such a dramatic and sudden increase in aircraft noise.”
The FAA review will consider whether changes in the types of aircraft, their altitude over the neighborhoods and other takeoff procedures played a role, said Rydeen, an FAA official.
“We don’t have enough data yet,” he said. “I want to assure you that the FAA takes these concerns seriously.”
Fueling the skepticism of some residents, the change that sent more flights over their homes had been in effect for a year before it was disclosed in September.
Flights over the Keewaydin and Ericsson neighborhoods from the closest runway increased 33 percent from January to September over the same period in 2010. The increase occurred even as overall departures from the runway declined.
While the neighborhoods still experience significantly less airplane noise than some other areas, the increase represents a big change for them.
“The noise that you’re not used to is obnoxious,” Odia Wood-Krueger, an area resident, told members of the Noise Oversight Committee.
Many of the residents who have complained of noise live outside the boundaries established years ago for noise-proofing homes. Chad Leqve, in charge of noise management for the Airports Commission, said the increased noise isn’t enough to expand those mitigation efforts.
But Wood-Krueger and others say they don’t want noise proofing, just quieter skies. “We want to be out on our decks over summer,” Bob Friedman said.
Looking for answers
Friedman, addressing the committee, voiced concerns that the sharp right turn after takeoff that routes planes over the neighborhoods is linked to factors other than new control-tower directions.
“It saves fuel in most cases and in all cases it saves flight time,” said Friedman, attributing his theory to a Delta pilot he declined to identify.
After the meeting, Bill Underwood, chief pilot at Delta who sits on the committee, said lower flights over the neighborhoods after takeoff would not save fuel.
“Your fuel conservation comes from getting to altitude as quickly as possible,” he said. He said there is no Delta policy to keep planes at a lower altitude after takeoff.
Complicating the debate over airport noise is disagreement between City Council members and the Airports Commission over how to measure and mitigate it.
The airport considers average noise levels, which Quincy said “doesn’t accurately reflect what people are experiencing on the ground. … The human ear does not hear in averages.”
