Access the Terrain and Obstacle Profile pane

The following steps allow you to open the Terrain and Obstacle Profile element's properties:

1. Click the new layout element titled Terrain and Obstacle Profile in the Contents pane.

   The Terrain and Obstacle Profile pane appears. This pane contains the Terrain and Obstacle Profile element's source and display properties, which you can dynamically adjust.

2. Click one of the following tabs at the top of the pane to open the element's properties:

   Options	Adjust general settings and set the source and sizing.
   Profile Options	Specify the grid's extent and symbology, runway details, and which terrain to display.
   Display	Specify how the element's border, background, and shadow will display.
   Placement	Set the element's size and position in the layout.

Options tab

By default, the Options tab is active.

1. Click the General drop-down arrow.
2. In the Name text box, change the name of the element in the Contents pane.
3. To hide the profile in the layout, uncheck the Visible check box.
4. Check the Locked check box to lock the profile element's position in the layout . If you don't check this box, you can adjust its position manually by dragging it in the layout.

   Remarque :

   If you check the Locked check box, the option to select the element in the layout is unavailable, but you can still select it to display its properties by clicking it in the Contents pane.

5. Under Source, click the Map frame drop-down arrow and choose the map frame corresponding to the inserted Terrain and Obstacle Profile element if there is more than one map frame in the layout.
6. Click the Profile Style drop-down arrow and choose a profile style.
   • Aerodrome Obstacle Chart
   • Precision Approach Terrain Chart
7. Set the type of approach to use in the profile. This depends on the features in the input OIS layer.
   • Straight
   • Curved

     Remarque :

     Choosing Curved requires the input OIS to contain approach surfaces created with the Create Curved Approach geoprocessing tool.

8. Set the OIS Layer parameter to the multipatch layer containing the OIS features to be profiled.
9. Specify the runway designator for the approach surfaces to be profiled in the Runway ID parameter, if necessary.
10. Click the Base Specification drop-down arrow and choose the surfaces on which the element will be based.

    The terrain and obstacles are shown in the profile based on the extent of the chosen base specification.

    Remarque :

    • Approach features from more than one specification in the input OIS layer (not excluded using a definition query) are available. If the selected specification has been created for both ends of the runway, the Terrain and Obstacle Profile will be shown for both ends of the runway.
    • The FAA 13A, FAA 18B, and Unified Facilities Criteria geoprocessing tools create surfaces for both high and low runway ends. The Runway Classification parameter input is applied to both runway directions. Using base specifications from these will show profiles for both runway ends.
    • The ICAO Annex 14 tool requires an input runway classification and is run on only one runway direction at a time. Run this tool only once for each runway direction and use the same runway classification to display both runway ends on the Terrain and Obstacle Profile element.
      • High end to low end
      • Low end to high end
    • The ICAO Annex 4 tool produces Runway End Surface features. The tool has no runway classification parameter, but run it only once for each runway direction to display both runway ends on the Terrain and Obstacle Profile element. This specification is intended for use with the Precision Approach Terrain Chart (PATC) profile style.
    • If an FAA FAR 77 Base Specification is chosen, an Optional Specification drop-down menu appears, allowing you to choose the opposite runway end to be profiled along with the base end. This allows for different specifications to be used for the high and low runway ends.
    • Base and Optional Specification surfaces are automatically shown on the Terrain and Obstacle Profile. Other relevant surfaces, such as Approach and Take Off Climb, in the OIS layer, can be displayed by checking their respective check boxes in the layout's Contents pane.
11. Check the Use Constant Ratio check box under Sizing.

    A Ratio parameter appears.

12. Specify the Ratio value to use.

    The default value is 10 in accordance with the ICAO specification that Aerodrome Obstacle Chart (AOC) profiles have a vertical dimension of 10 times the horizontal value. The value you enter is multiplied by the horizontal value to set the vertical value.

    Remarque :

    Don't check the Use Constant Ratio check box if you're making a PATC profile style, which allows you to vertically resize the element by specifying the Height value and its page unit of measurement.

13. Click Refresh Profile under General to view your changes on the map layout.

Profile Options tab

Once the Terrain and Obstacle Profile element is visible, further configuration and styling are required to create a finished product. Setting the Profile Options parameters allows you to create Terrain and Obstacle Profile elements similar to the following examples:

The Aerodrome Obstacle Chart (AOC) profile style is shown.

The PATC profile style is shown.

You can access the Grid, Runway, and Terrain parameters to style the element by clicking the Profile Options tab .

Configure the grid properties

The Grid section allows you to set the extent and symbology properties of the element's grid, including its divisions.

Set the extent

Complete the following steps to set the extent properties:

1. Click the Grid drop-down arrow to display the extent and symbology properties.
2. Click the Extent drop-down arrow.
3. Specify a division value for the Horizontal Scale parameter.

   Use the drop-down arrow in the field next to the value to choose a unit of measurement for the horizontal scale value.

4. Specify a division value for the Vertical Scale parameter.

   Use the drop-down arrow in the field next to the value to choose a unit of measurement for the vertical scale value.

5. Optionally, check the Auto Vertical Grid Extent check box to automatically set the grid's vertical extent to conform to the extent of the terrain and OIS layers.

   Remarque :

   • If you leave it unchecked, additional controls to enter numeric values for the Top and Bottom grid extents appear to limit the grid's display vertically by entering values.
   • If you're creating a PATC profile, uncheck the Auto Vertical Grid Extent check box to customize the extent of the vertical axis from zero. On PATC profiles, ground level at the runway end to be profiled is represented by zero, with positive and negative elevations from zero shown as needed.
     • If your PATC profile is covering the left end of the runway (as oriented on the layout), check the Use Runway Left End Elevation check box to set zero elevation for that end.
     • If it's profiling the right end, ensure that the check box is not checked.
6. In the Sub Divisions X parameter, set a numeric value for the number of subdivision lines to show along the horizontal (x) axis.
7. In the Sub Divisions Y parameter, set a numeric value for the number of subdivision lines to show along the vertical (y) axis.
8. Click the Curved drop-down arrow to configure the profile on the curved approach surface.
   • Check the Show Entire curved approach check box to profile the entire curved approach surface.
   • Uncheck the Show Entire curved approach check box to specify a value in meters that the curved approach surface will be profiled in the Maximum Distance parameter. The default value is 2000 meters.

Remarque :

If you're creating a PATC profile, additional Meter Scale Interval and Feet Scale Interval inputs are required for the vertical divisions and labels on the grid.

Set the symbology

Complete the following steps to configure the grid's display properties:

1. Click the Symbology drop-down arrow and set the properties for the grid's lines and text labels.
2. Set the symbol to use for the following:
   • Grid Division
   • Grid Subdivision
   • Grid Scale Text
   • Grid Left Text
   • Grid Right Text
3. Choose a color to use for the following:
   • Grid Division
   • Grid Subdivision
   • Grid Scale Text
   • Grid Left Text
   • Grid Right Text
4. Specify the grid line's width for the following
   • Grid Division
   • Grid Subdivision
5. Specify the font size for the text symbols:
   • Grid Scale Text
   • Grid Left Text
   • Grid Right Text

Runway

In the Runway section, you can set the symbol properties and labels for the runway depiction in the Terrain and Obstacle Profile element. The Precision increment box sets the decimal precision for the runway elevation labels.

If the profile data in the corresponding OIS layer contains runway points, you can use the Elevation Change Threshold increment box to refine the amount of labeled points. The elevation of consecutive runway points is evaluated for display based on this threshold value. If you enter a higher value, it will reduce the number of runway points displayed.

The Runway parameters set the symbol, color, and point width for the Runway feature. The Runway Text parameter sets the runway elevation text label's symbol, color, and size.

Terrain

Terrain is shown on the Terrain and Obstacle Profile element as a cross-section of where it planimetrically coincides with the OIS layer surfaces. Its display is divided into Max, Centerline, and Min terrain.

Terrain type	Description
Max	Profile of the maximum or highest elevations within the terrain
Centerline	The terrain profile along the centerline of the corresponding OIS layer's features
Min	Profile of the minimum or lowest elevations within the terrain

You can configure each of these terrain divisions using the Display Option drop-down arrow and the Terrain, Symbol, and Color parameters.
