An overview of the Obstruction Identification Surfaces toolset

The Obstruction Identification Surfaces toolset contains powerful tools to create OIS based on specifications.

Tool nameDescription

Create Curved Approach

Creates curved approach surfaces. This tool creates surfaces such as a polygon or multipatch features.

FAA 13A

Creates obstacle identification surfaces (OIS) based on the FAA 13A 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 differ by runway classification.

FAA 18B

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 differ by runway classification.

FAA FAR 77

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.

ICAO Annex 14

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 can project into an airspace. The type, function, and dimension of a surface differ by runway classification. This tool creates surfaces as polygon or multipatch features.

ICAO Annex 15

Creates obstruction identification surfaces based on the ICAO Annex 15 specification. These surfaces define areas of airspace around an aerodrome. Each area defines the limits to which an obstruction can project into an airspace. This tool creates surfaces as polygon or multipatch features.

Unified Facilities Criteria

Creates Unified Facilities Criteria (UFC) surfaces. Generates a primary surface, an approach surface, an inner horizontal surface, a conical surface, a transitional surface, a clear zone surface, an accident potential zone surface, and an outer horizontal surface.
