How long are airport grants typically valid through the Airport Improvement Program (AIP)?

• A. 5 years
• B. 7 years
• C. 10 years
• D. 12 years

Answer: (C)

Airport grants issued through the Airport Improvement Program (AIP) are generally valid for a period of 10 years. This timeframe allows airports adequate time to implement the projects funded by the grants, ensuring that they can plan, design, and complete significant improvements to their facilities or operations.

A 10-year validity period aligns with the long-term nature of airport infrastructure projects, which often require extensive planning, regulatory approval, and construction time. It provides airports with flexibility to manage their projects according to their budgets and operational needs, and to coordinate with other funding sources or necessary permits.

The other options reflect shorter or longer durations that do not align with the established norms for AIP grants, which is specifically tailored to accommodate the complexities involved in airport project development.
