No matter the size of the airport, one topic consistently comes to the forefront of the minds of those running them: funding. Where is it coming from? How much can be obtained? Will it continue? How do I get more? While there is no crystal ball to tell what the future holds in terms of funding specifically, there is a document that can lay out an airport’s future and help to secure funding from the Federal Aviation Administration (FAA) and beyond. That document is the Airport Layout Plan (ALP).
FAA policy has long treated the ALP as the airport’s official blueprint, and federal rules require federally aided airport development to be done in accordance with an FAA-approved ALP. In other words, an ALP is not just a drawing; it is the map that tells the funding system you are building the right thing in the right place.
FAA Advisory Circular (AC) 150/5070-6B explains that U.S. law requires, in part, a current ALP approved by both the sponsor and FAA prior to approval of an airport development project. It also ties the ALP directly to grant obligations, noting that Grant Assurance 29 requires sponsors to keep the ALP up to date and that an ALP is treated as current for a five-year period or longer unless major changes are made or planned. If an ALP is more than a decade old, it may still be operating safely today, but the airport becomes increasingly vulnerable to the words every airport sponsor dreads to hear: “We can’t fund that yet.”
What the ALP does for small GA airports
FAA AC 150/5070-6B is refreshingly direct about the ALP’s purpose. It calls the ALP a blueprint for development that helps ensure future projects maintain design standards and safety requirements, remain consistent with land use plans, and support airspace protection. It also describes the ALP as a public document used in community deliberations on land use and budget planning, and as a working tool for airport management and maintenance staff.
Those functions matter even more at smaller airports, where staff is often lean and capital dollars are precious. A current ALP helps an airport avoid “reactive development,” where projects get invented on the fly because a tenant needs a hangar or a pavement section fails. Instead, the airport can point to a staged plan that shows where development goes, and why.
It also protects airport management and stakeholders in the meetings that don’t feel like airport meetings—planning commission hearings, council budget workshops, and the occasional public comment session where someone confidently suggests relocating the runway “a little to the left.” A current ALP gives a clear, FAA-aligned record of aeronautical needs and the safety and airspace constraints that come with them. When the airport’s future is on paper, it is harder for future land use around the airport to drift into conflict.
Economic Impact: The ALP as a ‘Yes’ Machine
Airport managers are practical people. If a document does not help to answer “yes” to real-world needs, it becomes shelf décor. The ALP’s economic value is that it makes more “yes” answers possible—yes to grant eligibility, yes to staged development, yes to tenant growth, yes to long-term approach area protection.
At the national level, the FAA emphasizes that GA airports are a significant asset to the economy and the aviation system, and its GA study resources highlight the diverse roles GA airports play. For local decision-makers, one of the most effective ways to defend the airport is to quantify and explain that impact, and industry guidance encourages airports to use economic impact information to demonstrate a measureable role in the community.
A current ALP supports that story with credible, visual evidence. It identifies where hangars can expand, how apron capacity can grow, what access and utilities need to support development, and what safety and airspace protections must be maintained. It also aligns with the airport capital planning process the FAA uses to identify and track needs. The National Plan of Integrated Airport Systems (NPIAS) narrative describes airport capital needs as being driven by current and forecasted use, facility age, security requirements, and changing technology, and it ties those needs to the planning process that feeds national investment decisions. If the airport’s next improvements are to be understood as “inevitable and fundable” rather than “nice to have,” a current ALP is how that dialogue starts.
Conclusion: Plan today. Funded tomorrow
The good news is that planning is widely recognized as a valid, fundable investment because it reduces risk and improves project selection. The practical pathway is straightforward: coordinate early with your state or FAA planner, scope the work to fit the airport’s needs, and program the planning project so the ALP is current before the airport is trying to obligate construction dollars. FAA AC 150/5070-6B notes that an ALP update and narrative can be an appropriate alternative to a full master plan when the fundamental assumptions of the previous master plan have not changed, which often makes a targeted ALP update a right-sized approach for small airports.
An ALP update is an investment in momentum. It is how a small GA airport turns long-term needs into fundable projects, turns community questions into confident answers, and turns the “maybe someday” statements into “we’re ready when the opportunity arrives.” The ALP can look like just a set of lines and notes—until you realize those lines are the difference between a project that moves and a project that waits.
If your ALP is older than ten years, the most practical approach is to treat the update not as paperwork, but as a strategic request: confirm what exists, validate what’s needed, document what’s changing, and leave behind a blueprint that staff, partners, communities, and other airport stakeholders can use for the next decade.
