FAA FAR 77 (Aeronautical)

概要

Creates obstacle identification surfaces based on the specifications outlined in FAA FAR 77.

使用法

• The production database must be defined in the Data Management pane in the Production Properties dialog box.

• The Input Runway Feature Class must be Z enabled.

• 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.

• You can modify all measurement values from the existing preset values, but the generated geometry may not be valid.

• 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.

パラメータ	説明	データ タイプ
input_feature_class	The input runway dataset. The feature class must be polyline or polygon.	Feature Layer
input_feature_sql	A Structured Query Language (SQL) WHERE clause that selects a subset of features from input_feature_class.	SQL Expression
output_feature_class	The output feature class that will contain the generated obstacle identification surfaces.	Feature Layer
input_clear_way （オプション）	The length of the clear way.	Double
input_runway_type	The runway classification of the Input Runway Feature Class (input_feature_class). Utility visual approach —A runway built for propeller aircraft not exceeding 12,500 pounds gross weight. Aircraft using the runway employ visual approach procedures. Utility nonprecision instrument approach —A runway built for propeller aircraft not exceeding 12,500 pounds gross weight. Runway has an instrument approach procedure that uses air navigation facilities with horizontal guidance. The runway can also have area type navigation equipment with approved nonprecision instrument approach procedures. Visual visual approach —A runway that supports only visual approach procedures. Nonprecision instrument greater visibility —A runway with a nonprecision instrument approach procedure that allows for landing in visibility conditions greater than 200 ft. decision height. Nonprecision instrument approach low visibility —A runway with a nonprecision instrument approach procedure that allows for landing in low visibility conditions. Low visibility conditions include decision heights less than 200 ft. Precision instrument —A runway that uses an Instrument Landing System (ILS) or a Precision Approach Radar (PAR) for approach procedures.	String
input_ois_unit	The runway length linear unit of measurement. Feet —Runway length is in feet. This is the default. Meters —Runway length is in meters.	String
input_ois_slope	Angular unit of measurement for slope values. Grade (%) —Slope angle is expressed as a grade (inclination) in percent. Angle (°) —Slope angle is expressed in degrees. Rise (X:1) —Slope angle is expressed as X units of run per 1 vertical unit.. This is the default.	Long
primary_surface	Toggle On/Off Primary Surface generation. CREATE_PRIMARY_SURFACE —Creates a primary surface. This is the default. NO_CREATE_PRIMARY_SURFACE —Does not create a primary surface.	Boolean
primary_surface_length	Primary Surface length excluding the length of the runway.	Double
primary_surface_width	Primary Surface width excluding the width of the runway.	Double
conical_surface	Toggle On/Off Conical Surface generation. CREATE_CONICAL_SURFACE —Creates a conical surface. This is the default. NO_CREATE_CONICAL_SURFACE —Does not create a conical surface.	Boolean
conical_surface_slope	Conical Surface Slope.	Double
conical_surface_offset	The length of the conical surface.	Double
horizontal_surface	Toggle On/Off Horizontal Surface generation. CREATE_HORIZONTAL_SURFACE —Creates a horizontal surface. This is the default. NO_CREATE_HORIZONTAL_SURFACE —Does not create a horizontal surface.	Boolean
horizontal_surface_radius	Horizontal Surface Radius.	Double
horizontal_surface_height	Horizontal Surface Height.	Double
approach_surface	Toggle On/Off Approach Surface generation. CREATE_APPROACH_SURFACE —Creates an approach surface. This is the default. NO_CREATE_APPROACH_SURFACE —Does not create an approach surface.	Boolean
approach_surface_extendedwidth	The width of the approach surface outer edge.	Double
first_section_length	Approach Surface First Section Length.	Double
first_section_slope	Approach Surface First Section Slope.	Double
transitional_surface	Toggle On/Off Transitional Surface generation. CREATE_TRANSITIONAL_SURFACE —Creates a transitional surface. This is the default. NO_CREATE_TRANSITIONAL_SURFACE —Does not create a transitional surface.	Boolean
transition_surface_slope	Transitional Surface Slope.	Double

コード サンプル

FAAFAR77 example (Python window)

The following Python window script shows an example of the FAAFAR77 function.

# Input Runway Feature Class - change this path
Input_fc = r'Database Servers\your_server_SQLEXPRESS.gds\ASP_PD (VERSION:dbo.DEFAULT)\ASP_PD.DBO.ADHPSurfaceLine' 

# Output Feature Class - this feature class must exist
Output_fc = "C:\\data\\work.gdb\\ObstacleArea_FAAFar77"

# Import the toolbox - verify this path exists
arcpy.ImportToolbox(r'C:\Program Files\ArcGIS\Desktop10.0\ArcToolbox\Toolboxes\Aeronautical Tools.tbx')

# exec FAA FAR 77
