A Federal Aviation Regulation (FAR) Part 150 Study is a voluntary noise exposure and land use compatibility study prepared by an airport to identify existing noise exposure, identify potential future noise exposure, to evaluate various alternatives, and to make recommendations as to viable noise abatement/mitigation measures. This Study will examine both aircraft operational measures and land use measures which will be developed with community and stakeholder input.
The overall purpose of a Part 150 Study is to reduce the number of people affected by significant aircraft noise levels within acceptable economic, environmental, and legal parameters. The Ted Stevens Anchorage International Airport is updating their previous Part 150 Study because the Federal Aviation Administration (FAA) requires that the Airport have current Noise Exposure Maps to receive federal funding for noise mitigation. The existing Noise Exposure Maps are 10 years old. Additionally, over the past 10 years there have been changes to aircraft fleet mix, change in aircraft activity levels, updates to the noise model used for analysis, and changes in the airfield development.

The Study identifies and evaluates aircraft noise and land use for both existing and future conditions. The Study contains two primary components: the Noise Exposure Maps (NEMs) and the Noise Compatibility Program (NCP). The other main Part 150 Elements include:
- Study Mobilization
- Inventory of Existing Conditions
- Forecasts of Aviation Activity
- Existing Noise Exposure Contour
- Future Noise Exposure Contour
- Existing and Predicted Future Baseline Noise Intrusions
- Future Noise Compatibility Alternatives
- Future Land Use Alternatives
- Noise Compatibility Program
Unique elements to this Part 150 Study Update include the use of supplementary noise metrics, evaluation of ground run-up noise, summer and winter noise measurements, and extensive community involvement.
An important part of the Study is the involvement of the public and other stakeholders. Involved parties include: Airport Management, the Federal Aviation Administration, Aircraft Operators, Airlines, a Study Input Committee, Airport Tenants, Surrounding Neighborhoods, Surrounding Jurisdictions, Airport Users, Consultant Team, and Other Interested Parties. The public involvement process will include meetings and open house workshops where the public can review Study related information, ask questions, and provide comments on the Study.
