Which Part governs common airport development measures such as runway extensions, new runways, and taxiway development?

• A. Part 150
• B. Part 161
• C. Part 139
• D. Part 77

Answer: (A)

Part 150 sets the framework for noise compatibility planning around airports and the development measures used to manage that impact. It guides how airports evaluate changes like runway extensions, new runways, or taxiway upgrades, and how they implement mitigation actions through a Noise Compatibility Program. This includes required noise exposure mapping, planning for capital improvements and land use, and engaging communities to minimize noise effects. Other Parts cover different areas—Part 77 deals with objects affecting navigable airspace, Part 139 covers airport certification and safety, and Part 161 addresses notices of proposed construction or alteration for noise-related issues—but they do not govern the broad planning and implementation of development measures in the way Part 150 does.
