Summary

Defines the main words used in this part of the law. An airport capacity enhancement project is work to build or lengthen a runway (including buying land, taxiways, or safety areas tied to it) or other airport projects the Secretary says will help cut air traffic delays. An airport sponsor has the meaning given in section 47102. An aviation safety project is work whose main goal is to reduce injury or damage as the FAA Administrator decides, or to follow an NTSB recommendation as the Administrator decides, or to meet FAA airport certification rules (part 139, title 14). A congested airport is one that both made up at least 1 percent of U.S. delayed aircraft operations in the latest year with data and is listed in table 1 of the FAA’s Airport Capacity Benchmark Report 2004 (or a successor report). A Federal agency is a U.S. government department or agency. A general aviation airport construction or improvement project is runway work and related items (land, helipad, taxiway, safety area, apron, or navigation aids) at general aviation, reliever, or non‑primary commercial airports, or other projects the Secretary says help build capacity at those airports. A joint use airport is owned by the Department of Defense and used by both military and civilian aircraft. Terminal development has the meaning given in section 47102.
