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.
