The Airports layer (airports.tab) contains airports and runways. Airport
boundaries are represented by gray fill regions, and the airport runway regions appear
in a darker gray.
Note: Airport point locations are in the Landmarks layer and are
located at entry points to airports rather than at airport centroids.
The Airports layer data is merged from the following Federal Aviation Administration (FAA) landing facilities databases:
- National Flight Data Center (NFDC) database for February 1994
- National Plan of Integrated Airport Systems (NPIAS) database, current as of May 1994
- Air Carrier Activity Information System (ACAIS) database for calendar year 1992
- Terminal Area Forecast (TAF) for FY91.
