F-22 Plus-Up Environmental Assessment Joint Base Elmendorf-Richardson, Alaska
2011Co-Authors: John K Austin, Wesley D Birch, Cay Fitzgerald, Ellen Godden, Catrina D Gomez, Heather Gordon, Joseph A Jimenez, Claudia Laughlin, Kristi Regotti, Deborah L LasalleAbstract:Abstract : This EA has been prepared in accordance with the National Environmental Policy Act (NEPA). The analysis focused on the following environmental resources: airspace management and air traffic control, noise, safety, air quality hazardous materials and waste management, biological resources, cultural resources, land use, socioeconomics, and environmental justice. Airspace management would not be impacted by the additional six primary F-22 Aircraft. Additional portions of the Knik Arm, the Port of Anchorage, and land west of the Knik Arm would experience noise levels of 65 decibels (dB) Day-Night Average Sound Level (Ldn) or greater, but this change is not projected to significantly impact any human or natural resources, including threatened or endangered species. On February 22, 2011, the National Marine Fisheries Service evaluated the potential consequences and issued a finding of may affect but not likely to adversely affect Cook Inlet beluga whales. There would be no construction required. Hence, there would be no construction noise, no construction air emissions and no impacts to JBER cultural resources. Any hazardous materials associated with Aircraft would be handled in the existing specialized F-22 maintenance facility and controlled to protect air and water resources. An increase of 103 base positions (less than one percent of base employment) is not expected to substantially affect commute times and would result in no measurable effect upon the regional economy. No on- or off-base residences are exposed to noise levels greater than 80 dB Ldn. Workers on JBER are protected against possible noise impacts by adherence to DoD noise management guidelines. The 65 dB Ldn noise contours would not extend off base over residential areas. Disadvantaged populations would not be disproportionately affected by the proposed plus-up, and there would be no health or safety impacts to children.

Using software document evaluations to enhance software supportability
[1993 Proceedings] AIAA IEEE Digital Avionics Systems Conference, 1Co-Authors: F.c. Budlong, J.j. StankoAbstract:A study has been conducted to help increase the supportability of software for complex systems, specifically, for the F-22 Aircraft. The aim of the study was to identify areas of risk to software support, to develop methods to reduce that risk, and to identify metrics that would provide a strong indication of software supportability during development and after deployment. This paper provides an overview of a set of Software Document Evaluation Guidelines that was prepared to help ensure that acceptable documents will enhance software supportability and reduce software support risk. An overview is provided for: the F-22 definition of software supportability, how software document evaluations can enhance that supportability, and current guidelines use. It also defines a standardized software document evaluation process the Government is using on a sample of the software documents for the F-22 Aircraft to determine their acceptability. >

Acoustic loads prediction on jet Aircraft
1992Co-Authors: N. N. ReddyAbstract:A nearfield Aircraft noise prediction computer program is presented for the F-22 Aircraft. The dominant sources of noise are jet turbulent mixing noise, jet broadband shock noise, and fluctuating pressure under the turbulent boundary layer. All results from this investigation are presented in viewgraph format.
