ICAO Annex 15

Summary

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.

Usage

  • The Input Runway Features must be z-enabled.

  • This tool creates the OIS in an existing polygon or multipatch feature class. It can also be generated as a new polygon shapefile. A feature class used for the Target must include a vertical spatial reference.

Syntax

ICAOAnnex15_aviation (in_features, target, {highend_clear_way_length}, {lowend_clear_way_length})
ParameterExplanationData Type
in_features

The input runway dataset. The feature class must be z-enabled and contain polylines.

Feature Layer
target

The output feature class that will contain the generated obstruction identification surfaces.

Feature Layer
highend_clear_way_length
(Optional)

The length, in meters, of the area at the high end of the runway. An aircraft can make a portion of its initial climb over this area.

Double
lowend_clear_way_length
(Optional)

The length of the area at the low end of the runway. An aircraft can make a portion of its initial climb over this area.

ICAOAnnex15 example (stand-alone script)

The following Python window script demonstrates how to use the ICAOAnnex15 tool.

import arcpy

# set gp environment
arcpy.env.workspace = "c:/data/ois.gdb"
arcpy.CheckOutExtension("Aeronautical")

# Input Runway Feature Class
inFeatures = "RunwayCenterline"

# feature class that will contain the OIS surface
outFeatureClass = "ObstructionIdSurface"

# exec ICAOAnnex15
arcpy.ICAOAnnex15_aviation(inFeatures, outFeatureClass, 10, 0)

arcpy.CheckInExtension("Aeronautical")
