Which of the following is a typical item eligible for AIP funding?

The typical item eligible for Airport Improvement Program (AIP) funding is related to infrastructure development and enhancements directly associated with the safety and operational efficiency of airports. Runways and taxiways are critical components of airport infrastructure that ensure safe takeoffs, landings, and ground movements of aircraft. Since AIP funding is aimed at improving aspects of airport operations that affect public safety and capacity, supporting the construction, rehabilitation, or improvement of runways and taxiways is a primary focus of the program.

In contrast, luxury airport lounges, while valuable for passenger experience, do not directly enhance airport infrastructure in terms of safety or operational efficacy, and thus are not eligible for AIP funding. Similarly, retail shops and airline ticket sales systems do not fall within the scope of infrastructure improvements related to operational safety and efficiency at airports. These elements, while important for airport revenue and customer service, are generally funded through different means, though they may be indirectly supported by the overall health of the airport’s finances.
