Overview of Airport Improvement Program (AIP)

The Airport Improvement Program (AIP) is a federal-state partnership to assist airports in making improvements that ensure the safety and efficiency of our nation’s airport system. AIP grants are available to public agencies as well as non-profit and private entities that operate either publicly-owned or privately owned airports, with some restrictions. The Federal Aviation Administration (FAA) is responsible for administering the AIP, reviewing applications for funding and approving projects for construction.

AIP grants can be used to fund a variety of airport infrastructure projects including improvements to runways, taxiways and aprons; land acquisition; noise compatibility planning; environmental assessments; airport layout planning; terminal facilities construction, rehabilitation and expansion; engineering services for design of grantees’ projects; and landside access improvement activities. Eligible grant recipients can also use parts of the program funds to provide users with compensation in accordance with prescribed formulas based on specific criteria such as projections of lost revenue due to aircraft operations.

To be eligible for funds under the AIP program, an organization must be either a public entity that owns or operates an airport, or a nonprofit entity which has been leased or assigned responsibility by the public owner/operator of an airport. In addition, FAA review is required prior to any project that includes activities potentially affecting wildlife habitation areas or historical properties as defined in Title 16 United States Code Section 470f.

Benefits of AIP

The Airport Improvement Program (AIP) is an important part of the Federal Aviation Administration’s (FAA) mission to provide a safe and efficient national air transportation system. AIP provides funds for airport infrastructure and operational improvement projects, encouraging safety, capacity, security, and environmental improvements in American airports.

Benefits of AIP funding include:

  • Improved runway surface conditions to reduce incidents or accidents caused by poor visibility or snow/ice removal;
  • Upgraded navigational systems such as associated instrument landing systems, precision approach path indicators, VHF omnidirectional radio ranges, localizers and GPS technology;
  • Airport signage, marking and lighting upgrades;
  • Restriping of airfields;
  • Airfield security upgrades;
  • Construction or improvements of hangars;
  • Refueling equipment to help reduce aircraft ground delays;
  • Rehabilitation projects for runways, terminals/terminal buildings layouts and reconfiguration projects for enhanced flow control operations;
  • Upgrades for terminal baggage carousels to ease passenger flow;
  • Drainage repairs or improvements to avoid water from pooling in runways during wet weather operations;
  • Additionally unforecasted aircraft force majeure runway maintenance can be funded through AIP grants.


The Airport Improvement Program (AIP) provides funds to public or private agencies for the planning and development of public airports. The funds can be used on a wide range of eligibility criteria, such as improving runways, taxiways, and aprons, and the environmental protection of airports.

To qualify for the program, applicants must meet United Intranet Flyingtogether App criteria. Let’s look further into the eligibility requirements for AIP funding:

Who is eligible for AIP?

The Federal Aviation Administration’s Airport Improvement Program (AIP) provides grants to public agencies for airport development and planning, and to airports who serve commercial transportation.

AIP funds are essential to helping ensure the safety and efficiency of America’s airports.

In order to receive AIP grants, applicants must meet certain eligibility requirements as outlined by the FAA. An applicant must be a public agency or government entity, be in control of an airport that serves general aviation or scheduled commercial flights, and be in compliance with FAA environmental regulations. Generally, applicants must submit an application for projects over $3 million and must have enough revenue generated at the airport for costs associated with development or maintenance of the airport.

Once eligibility is established, the FAA reviews requests for AIP grants on an annual basis through their discretionary program selection process. The FAA reviews each application based on their commitment criteria such as safety issues, national priority objectives, and return value on investment (ROI). ROI is calculated by comparing measurable economic benefits with monetary costs over a specified period of time when compared to other projects under consideration. Once approved, each eligible project will receive a maximum grant amount that covers up to 95% of total project costs.

What types of projects are eligible for AIP funding?

The Airport Improvement Program (AIP) provides grants to public airports to fund projects that improve safety, enhance capacity and increase security of the nation’s airports. The types of projects and activities eligible for AIP funding include:

  • Airport land acquisition and relocations
  • Runway and taxiway development
  • Engineering studies
  • Noise compatibility programs
  • Environmental programs, including wildlife hazard assessments, bird/wildlife hazard management plans, erosion control

  • Installation of airport firefighting equipment
  • Security projects including surveillance systems and access control improvements
  • Safety projects such as crash rescue equipment for aircraft firefighting, Runway safety areas improvements, runway marking/lighting modifications.

What types of airports are eligible for AIP funding?

The Federal Aviation Administration (FAA) offers Airport Improvement Program (AIP) grants for airports owned by public agencies and operating for the benefit of the public. AIP funds are available for a variety of projects aimed at improving safety, security, capacity, accessibility and environmental sustainability in the national airspace system. To be eligible for AIP funding, an airport must meet specific criteria as outlined in 49 USC 405.

Generally speaking, airports that meet one or more of the following criteria will qualify to receive AIP funds:

  • Airports with regularly scheduled commercial air service.
  • Airports certified or publicly used by helicopters.
  • Reliever Airports, i.e., airports not a commercial service airport and which has an annual departing aircraft traffic load of fewer than 2 million enplanements each year and services primarily general aviation aircraft.
  • Small Hub Airports – these are reliever/medium hub airports primarily composed of general aviation operations whose most recently reported calendar year enplanements are between 2 million and 10 million.
  • General aviation (GA) airports – non-commercial service airport open to the public which have at least 3000 annual takeoffs/landings with more than thirty percent local GA traffic based on total annual payments per category How to Login to Flyingtogether Off Net.

Application Process

The application process for the Airport Improvement Program (AIP) is designed to ensure that airports of all sizes have access to the program and its benefits. Applicants must have an approved Airport Layout Plan (ALP) from the FAA that describes the proposed projects and the funding required.

The process for submitting a successful application will be described in this section:

How to apply for AIP funding

The Airport Improvement Program (AIP) is a Federal program that provides funding to both public and private airports for improvements or maintenance projects. These projects may include runways, terminals, preliminary engineering and studies, aircraft rescue and firefighting equipment and noise reduction initiatives.

To apply for AIP funding, applicants must submit an Airport Capital Improvement Plan (ACIP) to their local Airport District Office or state aeronautics office. This plan must describe the project in sufficient detail, including estimates of total expected cost of the project and its timeline. To qualify for the program, applicants must meet United Intranet Flyingtogether App criteria. The ACIP also needs to be consistent with the existing State Aviation System Plan (SASP). Different states have different criteria for developing their SASPs; therefore, applicants should contact their local FAA office to determine eligible application categories in advance.

In addition to providing a complete ACIP proposal, applicants are also required to submit any associated studies or analyses needed by the FAA before a grant award can be finalized Flyingtogether Employee Res. These might include environmental impact assessments, land surveys and noise-compatibility studies if applicable.

Additionally, applicants will need to provide financial statements showing an ability to meet at least 20 percent of the total development costs for larger projects with an airport layout plan or airport master plan submitted as part of those financial statements if applicable FAA before a grant award can be finalized Flyingtogether Employee Res.

As financing from the AIP is competitively awarded on a rolling basis throughout its fiscal year funding cycle, potential applicants should regularly check updates from state aeronautics offices or FAA offices for deadlines related to submitting applications as these Dates may change significantly from one fiscal year to another.

To ensure accurate submission requirements through this process, it is recommended that potential applicants engage during all phases – initial application proposal submission through post-award compliance – with dedicated aviation personnel who are familiar with all pertinent rules related AIP grants awards eligibility criteria.

What documents are required for the application?

All applications for the Airport Improvement Program must be submitted through using the FAA forms described on this page. The following documents are required for a complete application package:

  • Form 5100-127, Airport Sponsor Assurance Statement of Compliance, which outlines your airport’s intent to comply with the requirements of this program, as well as applicable federal regulations.
  • Form 5100-134, Application for Funds–Airport Improvement Program Update Form holds detailed information such as airport contact and owner or sponsor information; a brief project description; and an estimated project budget.
  • The completed Standard Facility Agreement/Grant Agreement (SFG) Map outlining the boundaries of existing FAA rights-of-way interests at your applicant airport and legal endorsements or signatures of government officials indicating their approval of all rights transferred or granted under this program.
  • Provide usernames and passwords that allow us access to the equipment so we can review information in advance.
  • Financial Plan which confirms that project funding obligations can be met by the proposed sources (e.g., passenger facility charges) and in compliance with applicable laws and regulations;
  • A copy of your environmental document(s), if applicable;
  • Any other documents specifically requested by the local FAA Airports District Office or Regional Office for use in evaluating your application relative to current environmental policies;
  • Proof of prompt payment from an external source necessary to meet any financial commitments due prior to award issuance; if a cohelper will be involved in financing construction costs related to an AIP funded project, appropriate state lobbyist registration certifications must also be included in order to receive reimbursement payments from AIP funds;
  • Evidence that all contractors comply with prevailing labor standards requirements associated with this program (WDOL)(Equal Opportunity Clause);
  • Evidence that reasonable efforts have been made by any bidder prior to award date to obtain waivers or reductions on special or hazardous materials needs associated with AIP projects (Equal Employment Opportunity Clauses);
  • Lastly, any other documents necessary for the completion of preaward submission steps identified by Grants Solutions or local FAA Airports District Office staff.

What is the timeline for the application and funding process?

The timeline for the Airport Improvement Program (AIP) application and funding process can vary, depending on the complexity of the project. Generally, airport sponsors should plan on 12-18 months between submitting an AIP-funded grant application and receiving funding.

Airports are encouraged to begin development of their projects before submitting a completed AIP grant application in order to better leverage limited FAA financial resources. Longer ranges may be applicable to projects with higher levels of complexity or novel approaches.

Applications can be submitted at any time during the fiscal year, but typically airports submit applications near the end of August or early September in order to maximize their possibility of receiving an award before fiscal year-end. Projects submitted in these months increase the likelihood that funds will remain available from awards made earlier in the fiscal year that were subsequently declined or deferred by applicants.

A review cycle starts once an application is received by FAA. This review cycle consists of:

  • Evaluation for eligibility
  • Technical approval
  • Environmental determination where applicable (such as geographic areas protected by federal law)
  • Proposed costs being reviewed by economic experts
  • A general consideration by FAA if project’s benefits are greater than its costs.

The most critical aspect at this point is availability of remaining funds that have not already been awarded during this fiscal year and/or paid out from prior years’ awards – because no new appropriations are made after each fiscal year end on September 30th each year without congressional authorization.


Airport Improvement Program funding provides financial assistance to public airports that improve their facilities and increase operations. The Airport Improvement Program (AIP) is the core of aviation funding and is administered by the Federal Aviation Administration. AIP funds must be used in accordance with the Agency’s grant assurance obligations and appropriate federal, state, and local laws.

This article will explore the various funding sources, grants, and associated requirements of the Airport Improvement Program:

What are the sources of AIP funding?

The Airport Improvement Program (AIP) is the primary source of federal funding for airport capital improvements and operations nationwide. AIP funds are authorized by Congress under Title 49 USC §47101 (in state or out of state airport projects) and administered by the Federal Aviation Administration’s Office of Airport Safety and Standards. AIP funding sources include Passenger Facility Charge (PFC) collections, Aviation Trust Fund contributions from fuel taxes and other federal appropriations.

The Passenger Facility Charge (PFC) is a passenger ticket surcharge imposed at individual airports that are then redistributed to airports for facility-related improvement projects, usually requiring FAA approval. Airports issue PFC bonds, which are guaranteed through trust agreements with the airlines. The federal government holds liability on behalf of airports if a project fails to meet expectations or if delinquent bonds have to be paid off prematurely.

The Aviation Trust Fund provides funds derived from aviation-related taxes collected on airline tickets, air cargo, depreciation tax on aircraft parts, fuel tax on aviation transportation fuels, import tax levied on nonresident aircraft maintenance and supplies as well as other airline-related items. Money generated from these taxes goes directly into the trust fund, which is then used to support AIP grants given to airports across the country for airport improvement projects such as new lighting systems or runway repairs.

In addition to PFCs and Trust Fund contributions, Congress can also elect to appropriate funds directly from its general fund for airport construction projects or programs that may not qualify for traditional AIP grants. Typically these appropriations will only apply if an airport project meets certain safety requirements or serves an important economic purpose that would benefit national interests in some way – such as job creation or increased efficiency in airport operations resulting in lower consumer fares.

How are funds allocated?

The Airport Improvement Program (AIP) is the primary source of funding for airport capital infrastructure needs. It is funded through taxes on aviation fuels and other airline user fees. The AIP provides funds to public airports for proposed projects that are eligible under the federal regulations and eligible cost categories, as outlined in Title 49, Code of Federal Regulations (CFR).

Airport project grants are awarded by the Federal Aviation Administration (FAA) in compliance with the AIP guidelines. The amount of each project grant is determined by the FAA based on several criteria, including federal eligibility standards, airport eligibility criteria, national or regional impact, project need and cost effectiveness.

Funds are allocated using an equitable distribution formula based on a number of factors such as:

  • geographic location
  • quantity and quality of service area enplanements
  • existing capacity constraints
  • existing system demands

Funds also must be used for projects that serve a public purpose, benefit aviation activity at the airport or benefit civil defense operations.

What types of projects are eligible for AIP funding?

The Federal Aviation Administration’s Airport Improvement Program (AIP) provides grants to public agencies and airports for the planning and development of public-use airports that are included in the National Plan of Integrated Airport Systems (NPIAS). Projects eligible for AIP funding use clear, federally established criteria to determine the extent of airport improvements needed.

Projects eligible for AIP funding must contribute to one of two purposes:

  1. Projects that preserve, restore, or enhance safety, security, environmental health or access at existing airport facilities;
  2. Projects to construct new airport facilities.

Eligible AIP projects include airside and landside improvements such as:

  • Runway/taxiway projects such as paving, lighting or other related projects;
  • Construction and extension of new runway(s)/taxiways;
  • Resurfacing ramps, aprons and other airfield pavement marking activities;
  • Obstruction removal from runways/taxiways/aprons;
  • Instrument landing systems or Automated Weather Observing Systems installation or upgrades;
  • Airport signage and pavement markings;
  • Airport layout plans;
  • Snow removal equipment acquisition, construction or upgradation;
  • Navigational aid equipment installation and acquisitions;
  • Wildlife hazard managements (habitat modifications);
  • Terminal Construction like building interiors renovations/improvements etc.;
  • Lighting system upgrades etc.;
  • Security related projects like perimeter fencing installation;
  • Multimodal access facilities including parking areas extending beyond terminal buildings like bus parks etc.;
  • Acquisition of land required in order to carry out an eligible project;
  • Environmental assurance system: Data collecting systems that monitor aviation emissions with mandatory alerts sent when certain thresholds are exceeded;
  • All types of noise abatement activities are eligible for AIP funding including insulation for dwellings adjacent to airports;
  • Additionally Airport Vehicle Access System (AVAS) is also a part of this program which operates ground access systems connecting runways with terminal areas throughout the country. Such projects provide reliability through barriers deployed along certain routes.


The airport improvement program (AIP) offers a variety of resources to help improve the safety and efficiency of airports. These resources can include grants, technical assistance, and other services. This section will provide an overview of the AIP’s resources and how they can be used to improve airports.

What resources are available to help with the AIP application process?

The application process for the Airport Improvement Program (AIP) is designed to be accessible and easy to understand. The Federal Aviation Administration (FAA) provides full and helpful resources to help airports apply for AIP funds.

The FAA’s web page on the Airport Improvement Program provides an overview of the grant program, including eligibility requirements and how applications will be evaluated. Additionally, they offer a comprehensive handbook that can be used as an AIP guide, featuring detailed information on each of the procedures necessary for grant applications. Additionally, state aviation departments may offer grants available outside of those offered through AIP.

The FAA also has an online form that can help guide users in understanding the funding rules for projects within their airport’s budget or in developing their own proposed project list. With this resource, applicants are able to get customized cost estimates from airports, develop six-year action plan records and view grant awards they have received in past years.

For additional assistance with developing projects and completing grant forms, airport personnel may contact any of the Regional FAA Offices who can provide additional information related to local grants programs and give guidance on particular questions an applicant may have about specific elements of their grant application process. Applicants are also encouraged to contact their respective state’s department of aviation, which may provide technical assistance with any doubts or questions about forms, filing deadlines or procedures mandated by state law and regulations.

What other organizations provide AIP funding?

In addition to the Federal Aviation Administration’s Airport Improvement Program (AIP), there are several other organizations that may provide funding to airports for various types of improvements and expansion projects. These organizations range from state and local governments to private companies, non-profit organizations, and private foundations.

State governments often have their own airport improvement programs which may provide additional funding for certain projects. These programs often include matching funds from the Federal government as well as local or other sources of revenue. Typical projects funded by state government programs include runway lights and taxiway upgrades, construction of deicing systems, improving schedule performance and safety, landing aids and obstruction removal.

Other organizations providing AIP funding include:

  • Local governments
