What does FAR Part 161 pertain to?

FAR Part 161 specifically addresses noise access restrictions on aircraft operations at public use airports. This regulation is important as it provides a framework that allows airports to implement measures related to managing noise pollution. It enables airports to establish restrictions on the types of aircraft that can operate during certain hours or to limit operations based on noise levels.

By establishing noise control measures, airports aim to balance the needs for air transportation with the community's quality of life, especially in areas surrounding the airport that may be significantly affected by aircraft noise. The rule requires airports to follow a defined process that includes public participation, thereby ensuring that local communities have a voice in decisions that may affect them.

The other options, while related to airport operations, do not align with the focus of FAR Part 161. Airport funding opportunities deal with financial aspects, runway safety measures pertain to the physical safety of operations on runways, and passenger terminal expansions relate to the physical infrastructure of airports. None of these areas are covered under the specific concerns of noise management that FAR Part 161 addresses.
