Description |
|---|---|
Creates obstruction identification surfaces based on the FAA 18B specification. These surfaces describe airspaces that should be free of obstructions. Surfaces are used to support planning and design activities. The type, function, and dimension of a surface differs by runway classification. This tool creates surfaces as polygon or multipatch features or triangulated irregular networks (TINs). | |
|
Creates obstruction identification surfaces based on the FAA FAR 77 specification. These surfaces describe airspace segments that are clear of obstructions. The type, function, and dimension of a surface differs by runway classification. This tool creates surfaces as polygon or multipatch features, or triangulated irregular networks (TINs). |
|
Creates obstruction identification surfaces based on the ICAO Annex 14 specification. These surfaces define areas of airspace around an aerodrome. Each area defines the limits to which an obstruction may project into an airspace. The type, function, and dimension of a surface differs by runway classification. This tool creates surfaces as polygon or multipatch features, or triangulated irregular networks (TINs). | |
