On-Call Aviation Noise Consulting:

San Francisco International Airport

 

BridgeNet International has been retained by the City of San Francisco to provide support services to the San Francisco International Airport Noise Abatement Office since 1999. These services include acoustical consulting and software development, utilizing BridgeXtreme to assist the Airport in the evaluation and development of noise abatement programs. As part of the consulting services, BridgeNet analyzed the Standard Offset Instrument Approach (SOIA) project for the Noise Abatement Office.

 

Project Profile, Model the Standard Offset Instrument Approach:

 

The project included visually depicting the existing Runway 28R/L ILS approach and proposed SOIA in 3-dimensions using BridgeXtreme. The project also involved the development of CNEL noise contours to comply with NEPA regulations; these contours showed that there would not be a 1.5 CNEL increase or decrease at the 65 CNEL noise level. Noise data from the Airport’s ANOMS noise monitoring system was used to create an INM input file from the actual flight and radar data, comparing conditions pre- and post-SOIA implementation. This data was used to analyze actual noise from specific aircraft and generate a grid analysis for the arrival procedure.

Noise Monitoring and Management Systems:

Jackson Hole Airport

 

The Jackson Hole Airport is located in one of the country’s most natural and breathtaking areas, within the Grand Teton National Park. The pristine and sensitive environment, coupled with several administrative authorities, demanded that the design criteria for the Noise Management System (NMS) meet rigid requirements while blending in with the surrounding environment.

 

BridgeNet International, teaming with hardware vendor 01dB, installed the original six (6) permanent NMS around the airport and provide a public access display viewable over the Internet. Some of the sites presented installation challenges that were met by installing solar panels for electrical power and wireless connections for high speed data transfer, a first for any NMS in the United States. This obviated the need to trench or pole the sensitive topography and has been hailed as a great success.

 

Additionally, the reporting and display software allows the airport board to share with the public and disseminate important information regarding noise procedures and compliance measures. The BridgeNet suite of software is being utilized at Jackson Hole Airport as programs highlighting the desire to address noise issues in the most complete and thorough manner available.

 

In fall of 2008 the FAA installed new technology BI-6 radar at the airport. With the installation of radar, the noise monitoring system was also upgraded. The upgrade consisted of numerous components, including; access to the BI-6 radar data, weather data and the additional of new features to the remote noise monitoring stations. The radar data connection allowed for the noise monitoring system to correlate an aircraft noise event to the aircraft causing the event. At the same time the noise monitoring stations were also upgraded to measure detectability. Detectability follows along the Volpe standards for measuring aircraft noise in a park setting. The audible contribution of aircraft and other noise sources to the Park’s Natural Quiet can be approximated using the detectability metric. The upgrade allows the noise monitoring system to more accurately measure the aircraft noise levels at the noise measurement points and to also quantify the aircraft audibility levels at these locations.

Noise Contour Modeling

BridgeNet has provided noise contour modeling for hundreds of independent noise studies and as part of numerous Part 150 Study and Part 150 Study Update programs. Each noise contour presents with unique issues, ranging from extreme terrain challenges to correlation of thousands of noise events with associated radar data.

Most recently, BridgeNet has provided noise contour modeling for the following projects:

Dallas Fort/Worth International Airport Vision 2030

BridgeNet, working with the Lopez Garcia Group, provided DNL noise contours for the Vision 2030 program at Dallas Fort/Worth International Airport. The analysis involved correlating approximately 200,000 data points from the noise and operations monitoring system with radar data to correlate aircraft noise events with flight tracks, therefore identifying aircraft noise events with specific aircraft. Using in-house proprietary software, BridgeNet generated 18 noise contours depicting multiple future-year scenarios and associated land use in the noise contours. Included in this analysis were flight tracks with RNAV headings and traditional vector-based flight tracks.

 

BridgeNet also provided additional consulting services which included land use in the 65 DNL noise contour for many of the future alternatives as well as extensive analysis and documentation for using alternative INM inputs. This documentation was included in a letter to the FAA for approval to change INM inputs to more accurately reflect conditions at DFW, including stage length profiles based on radar data instead of standard inputs.

Aspen/Pitkin County Airport

Aspen/Pitkin County Airport has used the airport consulting services of BridgeNet International for bi-annual noise monitoring and DNL noise contour generation. Aspen/Pitkin County Airport is located in an area with mountainous terrain in the Colorado Mountains. This topography requires BridgeNet to pay special attention to the terrain when generating the bi-annual noise contours. Twice a year, BridgeNet creates DNL noise contours for Aspen, using data from its noise monitoring collection to correlate aircraft flights with noise events.

 

This data is also used as the baseline for the Fly Green/Fly Clean Program implemented at Aspen/Pitkin County Airport.
