サマリー

Creates obstruction identification surfaces (OIS) based on the ICAO Annex 4 specifications for either a Take-Off Flight Path Area or a Precision Approach Terrain Area.

A Take-Off Flight Path Area is used on ICAO Aerodrome Obstacle Charts, Type A and Type B. These surfaces are defined to identify the area coincident with the runway Take-Off Flight Path where obstacles should be identified in compliance with the operating limitations of ICAO Annex 6, Part I, Chapter 5, and Part III, Section II, Chapter 3. The Takeoff flight path area is defined pursuant to ICAO Annex 4, Chapter 3, 3.8.2.

A Precision Approach Terrain Area is used in ICAO Precision Approach Terrain charts. These surfaces aid in the analysis of the terrain and features in a defined portion of the final approach that is depicted on the Precision Approach Terrain chart type pursuant to ICAO Annex 4, Chapter 6, 6.5.1.

To generate the surfaces, a runway centerline is needed as a reference for the surfaces. Optionally, a threshold point feature class can be input to supply the locations of displaced thresholds, if any. This tool generates the surfaces as polygon or multipatch features.

使用法

• [入力滑走路フィーチャ] パラメーターは、Z 対応である必要があります。

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

• The Target OIS Features parameter value must have a vertical spatial reference.

• OIS tools are flexible and accept a variety of input and output feature class types. For more information, see the OIS Input and Output schemas.

• The Input Threshold Point Feature parameter can be used to supply x-, y-, and z-geometry for displaced threshold features. If displaced thresholds are included, surfaces will be constructed based on their x-, y-, and z-geometry instead of their corresponding runway feature endpoint.

• To create a JSON file for the Custom JSON File parameter, use the CustomizeOIS.exe file that is part of the ArcGIS Aviation data package available from My Esri.

ラベル	説明	データ タイプ
Input Runway Features	The input runway dataset. The feature class must be z-enabled and contain polylines.	Feature Layer
Target OIS Features	The target feature class that will contain the generated obstruction identification surfaces.	Feature Layer
Surface Generation	Specifies the types of surfaces that will be created. Precision approach terrain area— A surface that is 60 meters either side of the extended runway centerline to a distance of 900 meters from the threshold, with a 3 percent slope rising outward from the threshold will be created.The surface will be created pursuant to ICAO Annex 4, Chapter 6, 6.5.1. Takeoff flight path area— A surface with a 180 meter width at its point of origin (end of runway or clearway), which increases at a rate of 0.25D to a maximum of 1800 meters, where D is the distance from the point of origin will be created. This surface extends to a distance of 10 kilometers and has a 1.2 percent slope ascending outward from the point of origin. The surface will be created pursuant to ICAO Annex 4, Chapter 3, 3.8.2.	String
Runway Direction (オプション)	Specifies the end of the runway where the approach surface will be created. High end to low end—The approach surface will be created at the high end of the runway to the low end. If a displaced threshold point exists at the high end of the runway, that point will be honored when creating the OIS. Low end to high end—The approach surface will be created at the low end of the runway to the high end. If a displaced threshold point exists at the low end of the runway, that point will be honored when creating the OIS.	String
Length of Clearway (オプション)	The length of the area beyond the runway in meters.	Double
Input Threshold Point Features (オプション)	Supplies x-, y-, and z-geometry for displaced threshold features. If displaced thresholds are included, surfaces will be constructed based on their x-, y-, and z-geometry instead of their corresponding runway feature endpoint.	Feature Layer
Custom JSON File (オプション)	The import configuration, in JSON format, that creates the custom OIS. To create a JSON file for this parameter, use the CustomizeOIS.exe file that is part of the ArcGIS Aviation data package available from My Esri.	File
