Краткая информация

Creates a Precision Approach Path Indicator (PAPI) Obstacle Clearance Surface (OCS) based on the FAA Engineering Brief (EB) 95.

A PAPI OCS determines which objects are vertical obstructions. An object is considered a vertical obstruction if it penetrates the PAPI OCS. Surfaces are used to support planning and design activities.

Использование

• Параметр Входные объекты взлетно-посадочной полосы должен поддерживать z-значения.

• This tool creates the obstruction identification surfaces (OIS) in an existing polygon or multipatch feature class. They can also be generated in an existing polygon shapefile. If a feature class is selected for Target OIS Features, it 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 Airport Control 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.

PAPIObstacleClearanceSurface example (stand-alone script)

The following Python script demonstrates how to use the PAPIObstacleClearanceSurface function.

import arcpy

arcpy.CheckOutExtension("Airports")

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

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

# Define surface dimensions
runway = "HIGH_RUNWAY_END_DESIGNATOR"
length = 4
divergence = 10
slope = 3
distance_from_threshold = 700
start_height = 35

# Generate PAPI Obstacle Clearance Surface
arcpy.aviation.PAPIObstacleClearanceSurface(inFeatures, outFeatures, runway,
                                            length, divergence, slope,
                                            distance_from_threshold, start_height)

arcpy.CheckInExtension("Airports")
