Desktop Help 10.0 - ICAO Annex 14 (Aeronautical)

Summary

Creates obstacle 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 obstacle may project into an airspace. The type, function, and dimension of a surface differs by runway classification. This tool creates surfaces as polygon features.

Usage

The production database must be defined in the Data Management pane of the Production Properties dialog box.
The Input Runway Features must be Z enabled.
The selection you make in Runway Classification will automatically populate most of the surface parameters. You can modify these existing preset values, but the generated geometry may not be valid.
The tool does not create the Output Feature Class. You can specify the ObstacleArea feature class as the Output Feature Class. You can find the ObstacleArea feature class in your production database. The Output Feature Class must exist, be Z enabled, and have the same geometry type and fields as the ObstacleArea feature class.
The Output Feature Class must have a vertical spatial reference.
This tool always runs in foreground mode. If you run this tool with Background Processing checked on, the tool will automatically switch to foreground processing.
