Create Curved Approach (Aviation)

Disponible avec une licence Aviation Airports.

Disponible avec une licence Aviation Charting.

Synthèse

Creates curved approach obstacle identification surfaces (OIS) based on the supported specifications in ArcGIS Aviation. These curved approach surfaces are based on an input flight path and the information in the selected specification, for example, ICAO Annex 15, FAA 18B and classification. This tool creates surfaces in existing polygon or multipatch features.

Utilisation

• The Input Runway Features parameter value must be z-enabled.

  Remarque :

  Z-values are required to determine the slope and final height of the approach surface.

• The Input Flight Path Features parameter value must be polyline geometry and include an ObjectID field. The polyline endpoint of the Input Flight Path Features parameter value should be created within a 100 meter search radius of the end point of the Input Runway Features parameter value.

• The Input Flight Path Features parameter value can be 2D data, because the x and y-values are used to create the direction of the curve.

• To create a .json file for the Custom JSON File parameter, use the CustomizeOIS.exe utility included in the Aviation Airports Product Data download available from My Esri.

• The surfaces generated are based on the Specification and Runway Classification parameter values.

• The tool creates a curved approach surface in an existing polygon or multipatch feature class. If the Target OIS Features parameter value is a feature class, it must have a vertical spatial reference.

• The starting elevation of the curved approach surface will be the same as the runway end elevation.

• If the PATHID field is included in the Target OIS Features parameter value, it will be populated with the ObjectID value of its source Input Flight Path Feature. This allows Flight Path features to be related to their output curved approach surfaces. The PATHID field (long integer) must first be added to the Target OIS Features parameter value.

• 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.

inFeatures = r"C:\data\ois.gdb\RunwayCenterline"

# Input Flight Path Feature Class 
inFlightPathFeatures= r"C:\data\ois.gdb\TakeOffClimb"

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

# Speicfication
specification = "FAR77"

# Runway Classification
runway = "PRECISION_INSTRUMENT_RUNWAY"

# JSON
customJSON = r"C:\data\customOIS.json"

# Treshold Offset
thresholdOffset = 0

# Generate FAA 77 OIS
arcpy.aviation.CreateCurvedApproach(inFeatures, inFlightPathFeatures,
                                    outFeatures, specification, runway, customJSON, thresholdOffset)
