Anchorage residents will be able to tell Air Force officials Wednesday night what they think of jet fighter noise from Joint Base Elmendorf-Richardson, which is holding a public open house to consider proposed changes to the base’s flight pattern for its F-22 Raptors.

The meeting is scheduled for 6 p.m. to 9 p.m. at Clark Middle School on 150 Bragaw Street, according to a statement from base officials. An Air Force presentation will begin at about 6:30 p.m., with public testimony slated to begin at 7:15 p.m.

The proposals require an environmental impact statement, which in turn requires input from the public on the jets’ noise over Anchorage. A draft version of that statement is posted on a website discussing the base’s potential changes.

The Air Force is evaluating half a dozen options – as well as making no changes to the base’s current flight layout – which could affect how efficiently JBER can launch the stealth fighters for training missions from its north-south and east-west runways.

JBER’s current scheme of F-22 flights sees a quarter of the base’s Raptors launching eastbound, according to the statement, with the remainder split evenly between southbound and northbound departures. The jets land southbound.

Three options would see Raptors launch eastbound and land southbound, launch and land southbound or launch northbound and land southbound.

The other three alternatives, which involve a potential extension of JBER’s east-west runway, would see jets launch northbound and land westbound, launch eastbound and land westbound or launch northbound and land westbound.

Most options being considered by JBER would improve the F-22s’ efficiency, allowing for up to 8.5 percent more training time. One alternative, southbound launches and landings, would decrease training time by 9 percent.

From a noise standpoint, base officials believe only one of the options – eastbound launches and southbound landings – might increase noise over Mountain View and west Anchorage. The others are expected to either reduce noise or cause no discernible change in noise levels.

Comments can also be submitted on the proposal website, by email or by mail to JBER Public Affairs, Bldg. 10480, Sijan Ave. Suite 123, JBER AK 99506.
