ICAO Annex 15

Summary

Creates obstruction identification surfaces (OIS) based on the ICAO Annex 15 specification (Areas 2a, 2b, and 2c). These surfaces assist in determining the height restriction or removal of obstacles that pose a hazard to air navigation in and around an aerodrome. This tool creates surfaces as a polygon or multipatch features.

Usage

  • The Input Runway Features parameter 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 TIN or polygon shapefile. If a feature class is selected for Output Features, it must have a vertical spatial reference.

Syntax

arcpy.aviationois.ICAOAnnex15(in_features, highend_clear_way_length, lowend_clear_way_length, out_features)
ParameterExplanationData Type
in_features

The input runway dataset. The feature class must be z-enabled and contain points, polylines, or polygons.

Feature Layer
highend_clear_way_length

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

Double
lowend_clear_way_length

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.

Double
out_features

The output feature class or TIN that will contain the generated obstacle identification surfaces.

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_aviationois(inFeatures,10,0,outFeatureClass)
arcpy.CheckInExtension("Aeronautical")
