FAA 18B

Resumen

Creates obstruction identification surfaces based on the FAA 18B specification. These surfaces describe airspaces that should be free of obstructions. Surfaces are used to support planning and design activities. The type, function, and dimension of a surface differ by runway classification. This tool creates surfaces as polygon or multipatch features or triangulated irregular networks (TINs).

Uso

  • El parámetro Entidades de pista de entrada debe estar habilitado para z.

  • La selección que realice en Clasificación de pista rellenará automáticamente la mayoría de los parámetros de superficie.

  • When Runway Classification is set to Vertical Guidance, the output transitional surface will be split into four sections by a line perpendicular to the runway centerline. This does not apply when Output Features is set to TIN.

  • When Runway Classification is set to Vertical Guidance, the output conical and horizontal surfaces will be split into sections by a meridian and a parallel. The meridian intersects the Airport Elevation Point and the center point of the runway centerline. The parallel runs perpendicular to the meridian through the center point of the runway centerline. This does not apply when Output Feature Class is set to TIN.

  • Esta herramienta crea una OIS en una clase de entidades poligonales o multiparches ya existente. También puede generarse como nuevo shapefile TIN o poligonal. Si se selecciona una clase de entidad como Entidades de salida, deberá tener una referencia espacial vertical.

  • When this tool is run as a stand-alone Python script, horizontal and conical surfaces are not split. This is because the runway centerline cannot be analyzed to find the airport control points, which are used to split the surfaces.

Sintaxis

arcpy.aviationois.FAA18B(in_features, runway_type, highend_clear_way_length, lowend_clear_way_length, airport_elevation, include_merged_surface, out_features)
ParámetroExplicaciónTipo de datos
in_features

El dataset de pista de entrada. La clase de entidad debe estar habilitada para z y contener puntos, polilíneas o polígonos.

Feature Layer
runway_type

The runway classification of in_features.

  • NON_VERTICAL_GUIDANCE_TYPE_1 —A runway designed for visual maneuvers, nonvertically guided operations, and instrument departure procedures.
  • NON_VERTICAL_GUIDANCE_TYPE_2 —A specially prepared hard surface (SPHS) runway designed for visual maneuvers, nonvertically guided operations, and instrument departure procedures. SPHS runways have a primary surface that extends 200 feet beyond each end of the runway.
  • VERTICAL_GUIDANCE —A runway that uses precision guidance systems to support aircraft approach and landing.
String
highend_clear_way_length

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

Double
airport_elevation

The highest point on any runway in an airport, in feet. The units for elevation are based on the specification. The tool will automatically populate this value from a z-value in your aeronautical database if you are using the AIS or Airports data model. Airport elevation is stored in the z-value of the ADHP point feature class in the AIS data model. In the Airports data model, elevation is stored in the z-value of the Airport Control Point feature class for records with the Point_Type field populated with AIRPORT_ELEVATION.

Double
include_merged_surface

Indica si las superficies fusionadas horizontales y cónicas se incluyen o no en la OIS, además de las superficies regulares.

  • INCLUDE_MERGED_SURFACE —Incluye las superficies fusionadas en la salida de la OIS. Esta es la opción predeterminada.
  • NOT_INCLUDE_MERGED_SURFACE —No incluye las superficies fusionadas en la salida de la OIS.
Boolean
out_features

La clase de entidad de salida o TIN que contendrá las superficies de identificación de obstáculos generadas.

FAA18B example (stand-alone Python script)

The following Python window script demonstrates how to use the FAA18B tool.

import arcpy

# set gp environment
arcpy.CheckOutExtension("Aeronautical")

# Input Runway Feature Class
inFeatures = "C:\data\ois.gdb\RunwayCenterline"

# Feature class that will contain the OIS surface
outFeatures="C:\data\ois.gdb\ObstructionIdSurface"

# Airport variables
runway = "Vertical Guidance"
airportElev = 100

# Generate FAA1B OIS
arcpy.FAA18B_aviationois(inFeatures,runway,10,0,airportElev,
                      "INCLUDE_MERGED_SURFACE",outFeatures)
arcpy.CheckInExtension("Aeronautical")
