How long do AIP grants generally remain active?

• A. 10 years
• B. 15 years
• C. 20 years
• D. 25 years

Answer: (C)

AIP grants, or Airport Improvement Program grants, typically remain active for a duration of 20 years. This period allows airports sufficient time to implement the projects funded by these grants, which can involve complex planning, design, and construction processes. The 20-year period also provides flexibility for airports to manage any unforeseen delays or changes in project scope that may arise during the implementation phase.

The longer duration compared to some other federal funding programs acknowledges the significant investment and complexity involved in airport infrastructure projects. This allows airports to adequately utilize the funds and ensures that improvements can be made without the constant pressure of reapplying for funding or losing granted resources before completion of the project.
