Based aircraft as counted for the FAA, fiscal year 2024
Based aircraft, as a table
| aircraft | |
|---|---|
| single-engine | 7 |
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 13,000, the FAA's fiscal year 2024 (October 2023 to September 2024)
Takeoffs and landings, as a table
| a year | |
|---|---|
| general aviation, travelling | 8,000 |
| general aviation, local | 5,000 |
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.

What each kind does
- AME: Aviation Medical Examiner: a doctor who issues the medical certificates pilots must hold.
- DME: Designated Mechanic Examiner: tests candidates for the mechanic certificate (airframe and powerplant).
- DAR-T: Designated Airworthiness Representative, maintenance: issues airworthiness certificates and approvals for aircraft in service.
- Admin-PE: Administrative Pilot Examiner: handles certificate paperwork rather than flight tests.
Designees are listed with the name and contact details the FAA publishes for them on its designee locator (read October 10, 2026): the FAA lists them so that pilots, mechanics and companies can find them. Private individuals are not named, the site's policy at this time. A designee who would rather not appear here can ask us through the contact address on the About page. Each designee is placed at the main public airport of the town the FAA lists (or the nearest one to its zip code), so "nearby" means the town, not an exact address. All examiners by state.
