ICAO Annex 4 (Aviation)

Zusammenfassung

Creates obstruction identification surfaces (OIS) based on the ICAO Annex 4 specification for the Precision Approach Terrain chart.

These surfaces are designed to aid in the analysis of the terrain and features within a defined portion of the final approach that is depicted on the Precision Approach Terrain chart type. To generate the surfaces, a runway centerline is needed as a reference for the surfaces. This tool generates the surfaces as polygon or multipatch features.

Verwendung

  • The Input Runway Features parameter must be z-enabled.

  • The Target OIS Features parameter must be z-enabled.

  • If a feature class is selected in Target OIS Features, it must have a vertical spatial reference.

Syntax

ICAOAnnex4(in_features, target, {runway_direction}, {length}, {width}, {slope}, {height})
ParameterErklärungDatentyp
in_features

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

Feature Layer
target

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

Feature Layer
runway_direction
(optional)

Specifies at which end of the runway the approach surface will be created.

  • HIGH_END_TO_LOW_ENDFrom runway high end to low end. The approach surface will be created at the high end of the runway.
  • LOW_END_TO_HIGH_ENDFrom runway low end to high end. The approach surface will be created at the low end of the runway.
String
length
(optional)

The length of the surface in meters. The default value is 900.

Double
width
(optional)

The width of the surface in meters. The default value is 120.

Double
slope
(optional)

The slope of the surface in degrees. The default value is 3.

Double
height
(optional)

The start height of the surface in meters. The default value is 15.24.

Double

Codebeispiel

ICAOAnnex4 example (Python window)

The following Python window script demonstrates how to use the ICAOAnnex4 tool.

import arcpy

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

# Input Runway Feature Class
inFeatures = "RunwayCenterline"

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

# runway variables
runwayDir = "HIGH_END_TO_LOW_END"
length = 900
width = 120
slope = 3
start_height = 15.24

#_Exec_ICAOAnnex4
arcpy.ICAOAnnex4_aviation(inFeatures, outFeatureClass, runwayDir, length, width, slope, start_height)

arcpy.CheckInExtension("Airports")
