DTW PART 150 NOISE STUDIES
The Noise Compatibility Program (NCP) for DTW includes measures to reduce aircraft noise,
control land development, mitigate the impact of noise on non-compatible land uses,
and carry out and update the program as needed. The objective of the NCP
is to improve the compatibility between aircraft operations and noise sensitive
land uses in the area, while allowing the airport to continue to serve its role
in the community and state.
way to do this is by completing a Part 150 Study. The goal of the Study
is to work in conjunction with surrounding communities, aviation experts and airport
neighbors to establish a balanced, cost-effective and comprehensive NCP.
Airports are not required to complete a Part 150 Study. However, by doing so airports
become eligible for federal funds that may be used to conduct the Study and implement
some of the approved solutions that comprise the NCP. DTW has conducted
two Part 150 Studies.
FAR Part 150 Study (1992)
the FAA approved the first Part 150 Study, resulting in the Airports first NCP. It allowed for implementing operational actions such as:
- Preferential Runway Use
Fanning of Departures Flight Tracks
- Established Ground Run-up Procedures
- Construction of Noise Barriers
- Establishment of a Noise Office
the Airport to obtain federal discretionary funds for noise related projects, such
as property acquisition, residential sound insulation, and purchase assurance.
FAR Part 150 Study Update (2009)
changes had occurred at the Airport since the 1992 Study, including changes in the
number of flights, aircraft fleet mix, aircraft technology, and airfield improvements.
These new developments raised the possibility that areas affected by aircraft may
have changed, thus necessitating the need to update the 1992 Study.
2003 the Airport initiated the Part 150 Study Update.An integral part of the
Study was the establishment of a Study Advisory Committee (SAC). The Committee was comprised
of various individuals who included 14 local communities, Wayne County, State of
Michigan, the FAA, and other businesses and airport users. The SAC was an advisory
board who provided input and feedback relative to update recommendations.
2009, the FAA approved the update to the DTW Part 150 Study. Some of the recommendations
