Which of the following is NOT a standard of review under the NCP?

The standard of review under the NCP (Noise Compatibility Program) primarily focuses on managing and mitigating the impacts of airport noise and ensuring that various interests and responsibilities are balanced. Each of the correct standards centers around the core objectives of noise abatement, equitable treatment of airport users, and consideration of the FAA's broader responsibilities.

The option that is correctly identified as not a standard of review is related to implementing additional runway construction. While runway construction can be a part of airport development and expansion plans, it does not fall under the specific standards of review associated with noise compatibility. The NCP instead emphasizes reducing incompatible land use, preventing unjust discrimination among users, and safeguarding the FAA's broader responsibilities—not the physical expansion of facilities like runways.

Thus, the focus of the NCP is more on managing existing conditions and impacts rather than adding new runway capacity, which could lead to increased noise and a further complication of existing noise issues.
