Calculate ATS Route Attributes (Aviation)

Mit der Aviation Charting-Lizenz verfügbar.

Zusammenfassung

Calculates segment distance and bearing attributes on Air Traffic Service (ATS) route features. The tool can also calculate the FAA specific route attributes on a route segment and route collection.

This tool calculates the magnetic track and reverse magnetic track based on the magnetic variation at the endpoints of routes.

Verwendung

• The Input ATS Route Feature Layer parameter value must be a polyline.

• If the ATS Route Attributes parameter is set to Magnetic Track or Reverse Magnetic Track, the Magnetic Variation Date parameter must be specified.

• One or more of the following attributes can be specified for calculation. Calculated attributes will be written to the selected numeric fields in the Input ATS Route Feature Layer parameter value.

  • Length—The length of the route segment in nautical miles will be calculated.
  • True Track—The true north azimuth of the route segment's track from its start point will be calculated.
  • Reverse True Track—The true north azimuth of the route segment's reverse track from its end point will be calculated.
  • Magnetic Track—The magnetic north azimuth of the route segment's track from its start point will be calculated.
  • Reverse Magnetic Track—The magnetic north azimuth of the route segment's reverse track from its end point will be calculated.

• One or more of the following FAA specific route attributes can be specified for calculation if the Input ATS Route feature layer contains the FAA specific attributes: TRUETRACK2_VAL, REVERSETRUERACK2_VAL, MAGTRACK2_VAL, REVERSEMAGTRACK2_VAL, or TFLAG_CODE. Calculated attributes will be written to the selected numeric fields in the Input ATS Route Feature Layer parameter value.

  • FAA True Track—The true north azimuth of the route segment's track from its start point will be calculated using FAA specific rules.
  • FAA Reverse True Track—The true north azimuth of the route segment's reverse track from its end point will be calculated using FAA specific rules.
  • FAA Magnetic Track—The magnetic north azimuth of the route segment's track from its start point will be calculated using FAA specific rules.
  • FAA Reverse Magnetic Track—The magnetic north azimuth of the route segment's reverse track from its end point will be calculated using FAA specific rules.
  • FAA True Track2—The true north azimuth of the route collection from its start point will be calculated using FAA specific rules.
  • FAA Reverse True Track2—The true north azimuth of the route collection from its end point will be calculated using FAA specific rules.
  • FAA Magnetic Track2—The magnetic north azimuth of the route collection from its start point will be calculated using FAA specific rules.
  • FAA Reverse Magnetic Track2—The magnetic north azimuth of the route collection from its end point will be calculated using FAA specific rules.
  • FAA Altitude Change Status—A numeric indicator showing how a route's segment altitude changes from the previous segment in a route collection.

• Selecting at least one of the four FAA specific route segment-based bearing attributes (FAA True Track, FAA Reverse True Track, FAA Magnetic Track, or FAA Reverse Magnetic Track) will calculate bearing values for a route segment.

• Selecting at least one of the four FAA specific route collection-based bearing attributes (FAA True Track2, FAA Reverse True Track2, FAA Magnetic Track2, or FAA Reverse Magnetic Track2) will calculate bearing values for a route collection. For each ATS Route Feature in a route collection, the same route bearing value will be written. However, if the route collection has dogleg points, different bearing values will be calculated and written for the parts of a route collection that are bounded by them.

  The following additional input parameters will be required to perform any of the FAA specific bearing calculations:

  • Input DesignatedPoint Feature Layer
  • Input NavaidComponent Feature Layer
  • Input Designated Point Navaid Association Table
  • Input Navaid Association Table
  • Input Enrouteinformation Table

• The ATSRoute feature class in the AIS Charting data model can be used for the Input ATS Route Feature Layer parameter value. It contains the following fields that can be used as input fields: LENGTH_VAL, TRUETRACK_VAL, REVERSETRUETRACK_VAL, MAGTRACK_VAL, and REVERSEMAGTRACK_VAL.

  The ATS Route feature layer may contain the following FAA specific bearing attributes that can also be used as input fields: TRUETRACK2_VAL, REVERSETRUETRACK2_VAL, MAGTRACK2_VAL, and REVERSEMAGTRACK2_VAL.
