Based aircraft as counted for the FAA, fiscal year 2024
Based aircraft, as a table
| aircraft | |
|---|---|
| single-engine | 24 |
| multi-engine | 4 |
The FAA's count is the general-aviation aircraft kept on the field (singles, twins, business jets, helicopters) from its Terminal Area Forecast, the latest year with an actual count; airline fleets are never counted as based anywhere, so a big airline airport shows a small number. The register section below shows how many aircraft are registered to owners in town, a different measure again.
Takeoffs and landings a year about 11,555, the FAA's fiscal year 2024 (October 2023 to September 2024)
Takeoffs and landings, as a table
| a year | |
|---|---|
| air taxi and commuter | 4,670 |
| general aviation, travelling | 1,380 |
| general aviation, local | 5,475 |
| military | 30 |
Local flights stay in the traffic pattern or nearby, often practice; travelling flights arrive from or leave for somewhere else. Counts at airports without a tower are the FAA's estimates. How this compares nationally: Airports by the numbers.
