scope:

PURPOSE.

• Order 5090.5 establishes guidelines for managing and maintaining two federal plans that are essential to airport development: the National Plan of Integrated Airport Systems (NPIAS) and the Airports Capital Improvement Plan (ACIP). The Order also discusses the Office of Airports (ARP) NPIAS project database that supports these plans and its use for preparing the Secretary of Transportation's biennial NPIAS Report.

• The NPIAS identifies existing and proposed airports that are important to national air transportation, and it provides a forward-looking estimate of the type and cost of eligible Airport Improvement Program (AIP) development needed to meet the needs of civil aviation.

• The ACIP, a subset of the NPIAS plan for airport development, is the primary financial planning tool for systematically identifying, prioritizing, and assigning funds to help meet the capital project needs of airports within the NPIAS. The ACIP also provides the basis for grant planning and management under the AIP.
