Which federal program funds a significant share of eligible capital projects at public-use airports in the United States?

• A. National Infrastructure Grant
• B. Federal Airport Maintenance Fund
• C. Public Works and Development Grant
• D. Airport Improvement Program (AIP)

Answer: (D)

The key idea is that airport capital improvements are funded by a dedicated federal program, not general grants. The Airport Improvement Program provides grants specifically to public-use airports for eligible capital projects—things like runway and taxiway upgrades, terminal and security enhancements, safety improvements, and environmental or noise compatibility work. It’s administered by the FAA and financed through the Airport and Airway Trust Fund, making it a stable, targeted source of funds for building and modernizing airport infrastructure. The other options aren’t established federal programs that fund airport capital projects, so they don’t fit the scenario.
