$1.5 billion AVAILABLE for airport projects! 

The Airport Improvement Program - Supplemental Discretionary Grant (AIP-SDG) aims to support airport construction and planning. The AIP-SDG looks to fund projects that will create proportional impacts to all populations in a project area. Applicants can use the funding for improvement projects as well as sustainability projects. 

Funding Overview

  • For large and medium primary hub airports, the grant covers 75 percent of eligible costs (or 80 percent for noise program implementation).
  • For small primary, reliever, and general aviation airports, the grant covers a range of 90-95 percent of eligible costs, based on statutory requirements.

Eligible Applicants 

AIP grants for planning, development, or noise compatibility projects are at or associated with individual public-use airports (including heliports and seaplane bases). A public-use airport is an airport open to the public that also meets the following criteria:

  • Publicly owned, or
  • Privately owned but designated by FAA as a reliever, or
  • Privately owned but having scheduled service and at least 2,500 annual enplanements.

Further, to be eligible for a grant, an airport must be included in the NPIAS. The NPIAS, which is prepared and published every 2 years, identifies public-use airports that are important to public transportation and contribute to the needs of civil aviation, national defense, and the Postal service.

Recipients of grants are referred to as "sponsors." The description of eligible grant activities is described in the authorizing legislation and relates to capital items serving to develop and improve the airport in areas of safety, capacity, and noise compatibility. In addition to these basic principles, a sponsor must be legally, financially, and otherwise able to carry out the assurances and obligations contained in the project application and grant agreement.

Eligible Activities

  • Improvements related to enhancing airport safety, capacity, security, environmental sustainability, planning, or any combination of the above 
  • Planning for the feasibility of and options for unleaded aviation fuel infrastructure
  • Airport projects associated with pavement rehabilitation, reconstruction, and extension of the pavement's useful life
  • Noise planning and noise mitigation
  • Projects to plan for, relocate, and/or construct run-up locations to reduce community exposure to emissions from leaded aviation fuel usage
  • Emission reduction projects
