Create Aviation Communication, Navigational, and Surveillance surfaces

Mit der Aviation Airports-Lizenz verfügbar.

To identify whether buildings cause unacceptable interference to facilities, an international standard has been created to describe the parameters that are used to construct imaginary surfaces around these facilities. The Communication Navigational Surveillance Surfaces tool allows users to create these surfaces in accordance with ICAO EUR DOC 015.

Navigation directional facilities

The following are the navigation directional facilities:

  • ILS LLZ (medium aperture single frequency)
  • ILS LLZ (medium aperture dual frequency)
  • ILS GP M–Type (dual frequency)
  • MLS AZ
  • MLS EL
  • DME (directional antennas)

All navigation directional facilities have the following parameters:

  • a—Distance of the surface extending parallel from the antenna along the centerline of the directional fan.
  • b—Distance of the surface extending parallel from the antenna, opposite along the directional fan, along the centerline of the directional fan.
  • h—Height of the directionally sloped plane that describes the minimum height of interference.
  • D—Distance of plane extending from the antenna perpendicular to the centerline of the directional fan. Height is determined by value of a.
  • H—Height of the surface that extends from the bottom of the antenna up to the specified value that connects to the directional fan.
  • L—Distance from the center of the antenna, perpendicular to the centerline of the directional fan, to the connection point of the sloped directional fan.
  • r—Distance from the base of the antenna; describes the overall length of the directional fan.
  • Phi—Represents the angle of the directional fan starting at the distance of D.

For a visual depiction of these measurements, refer to the ICAO EUR DOC 015 document.

Create CNS surfaces for Omni Direction facilities

The following image is a depiction of surfaces created for Omni Direction facilities:

CNS Omni Direction surfaces

  1. In the Catalog pane, add a multipatch layer to your map using one of the following methods:
    • Expand Databases Datenbanken, expand the database containing your data, and drag the feature class onto the map.
    • Right-click the default database, click New, click Feature Class Polygon-Feature-Class, type the feature class name, choose Multipatch for the geometry type, select the coordinate system, and click Run Run.

    The layer is added to the map, and a feature template with default settings is automatically created.

  2. On the Edit tab, in the Features group, click Create Features erstellen.

    The Create Features pane appears.

  3. The Create Aviation CNS button appears in the Create Features pane under the Multipatch layer.
  4. Click Create Aviation CNS Create Aviation CNS.
  5. Choose Omni Direction.

    The Omni Direction parameters appear.

  6. Choose a specification from the Specification drop-down.
  7. Choose a classification from the Classification drop-down.
  8. You can maintain and accept the default values in the Construction Parameters, or edit them, if necessary.
    Hinweis:

    The Construction Parameters are dynamically dependant on the choices made in the Specification and Classification drop-downs.

  9. In the scene click a point for facility location to create a surface.
    Tipp:

    On the Edit tab, in the Snapping group, click Snapping Snapping, enable your snapping preferences, and move the pointer back to the map.

  10. Omni Direction CNS surface will be automatically generated.

Create CNS surfaces for Uni Direction facilities

The following image is a depiction of surfaces created for Uni Direction facilities:

  1. In the Catalog pane, add a multipatch layer to your map using one of the following methods:
    • Expand Databases Datenbanken, expand the database containing your data, and drag the feature class onto the map.
    • Right-click the default database, click New, click Feature Class Polygon-Feature-Class, type the feature class name, choose Multipatch for the geometry type, select the coordinate system, and click Run Run.

    The layer is added to the map, and a feature template with default settings is automatically created.

  2. On the Edit tab, in the Features group, click Create Features erstellen.

    The Create Features pane appears.

  3. The Create Aviation CNS button appears in the Create Features pane under the Multipatch layer.
  4. Click Create Aviation CNS Create Aviation CNS.
  5. Choose Uni Direction.

    The Uni Direction parameters appear.

  9. In the scene click a point for facility location to create a surface.
    Tipp:
    On the Edit tab, in the Snapping group, click Snapping Snapping, enable your snapping preferences, and move the pointer back to the map.
  10. In the scene click another point for threshold.

    Uni Direction CNS surface will be automatically generated.
