Definition
A post-World War II United States government program established by the Federal Airport Act of 1946 that provided federal funding to states and municipalities for the planning, construction, and improvement of public-use civil airports. It was the first major federal grant program dedicated to building out the national civil airport system.
Plain English
A government funding program that gave money to towns, cities, and states to help them build and improve airports for public use after World War II.
Context Anchor
You will usually meet this term in aviation history or airport-development discussions, especially when reading about how the federal government helped expand the U.S. airport system after World War II.
Derivation
‘Federal Aid’ means funding provided by the national (federal) government to lower levels of government. The phrase mirrors earlier programs like the Federal Aid Highway Program, signaling that airports were now being treated as critical national infrastructure deserving federal investment.
Why Pilots Care
Many of the public airports pilots fly into today exist because of the runways, taxiways, and terminals originally funded under this program. It marks the moment civil aviation infrastructure became a federal priority rather than a purely local concern.
Intuition Check
Do not read this as any federal money that ever went to an airport. Here it refers to a specific historical U.S. airport grant program created after World War II.
Example Sentence 1
The small municipal airport's original runway was paved in 1948 with funds from the Federal Aid Airport Program.
Example Sentence 2
Before the Federal Aid Airport Program, most airport construction relied entirely on local taxes and private investment.
