Based aircraft, as a table
| aircraft | |
|---|---|
| single-engine | 66 |
| multi-engine | 4 |
| helicopters | 1 |
| other | 13 |
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 aircraft heard arriving or departing are the site's own record from the volunteer receiver network, airliners included; aircraft whose owners asked the FAA not to be displayed are left out. The register section below shows how many aircraft are registered to owners in town, a different measure again.
Takeoffs and landings a year about 83,075, the FAA's fiscal year 2024 (October 2023 to September 2024)
Takeoffs and landings, as a table
| a year | |
|---|---|
| general aviation, travelling | 18,000 |
| general aviation, local | 65,000 |
| military | 75 |
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.
