Good Afternoon:
This request relates to a recent change in north flow airplane departures from SeaTac. Due to this change, a large number of low elevation airplanes (mainly Alaska) now fly directly over Burien-Seahurst in contrast to historic custom. In response to a complaint I filed, Tom Fagerstrom (Community Specialist, Noise Programs, Port of Seattle) wrote to me as follows on 9/15/1`6:
"The Port of Seattle was recently informed that on July 28, 2016, the Federal Aviation Administration (FAA) implemented a new departure procedure for propeller aircraft departing to the north and turning west. The new procedure turns propeller aircraft directly after takeoff, which appears to place more aircraft over the Seahurst-Burien area. Although propeller aircraft have always overflown this area in the past, there is now a noticeable increase during north-flow operations. The Port is communicating directly with the FAA to express the communities’ concerns and better understand the FAA’s reasons for this change."
With that information as background, I request the following:
- Documents prepared (by FAA, the Port or others) on or after January 1, 2016 addressing why this new departure procedure was implemented (i.e., to relieve capacity issues, to address Alaska Airline requests, etc.)
- Documents received by the Port from FAA on or after January 1, 2016 related to this new departure procedure.
- Documents received by the Port from Alaska Airlines on or after January 1, 2016 related to this new departure procedure.
- Flight path maps for every day between July 28, 2016 and the date of this request showing the frequency and location/path of any aircraft departing to the north and then entering any airspace over Burien/Seahurst.
- As to the flights depicted in the maps requested in # 4, documents showing the elevation of said airplanes within Burien/Seahurst airspace.
- As to the flights depicted in the maps requested in # 4, documents showing the time of day or night said airplanes were within Burien/Seahurst airspace.
Thank you.
