Creating an altitude change procedure leg (Aviation)

The Procedure Leg CA, FA, VA function creates an altitude change procedure leg feature based on a single defined coordinate.

手順:

1. Start ArcMap.
2. On the menu bar, click Customize → Toolbars → Production Feature Builder.
3. Click the Feature Builder button on the Production Feature Builder toolbar.

   The Feature Builder window appears.

   ヒント:

   The Feature Builder window can be placed anywhere in ArcMap, or in the Table Of Contents window, with the aid of the arrows showing the possible placement positions.

4. Choose Procedure Leg CA, FA, VA in the list on the Functions tab.

5. Define a coordinate for the start point of the polyline by doing one of the following:
   • Clicking the Pinprick tool on the Production Feature Builder toolbar, then clicking on the map
   • Typing the coordinates in the cells on the Input tab in the Coordinates area
   ヒント:

   To view the input coordinates on the map, double-click the row headers for each coordinate.

6. Click the cell next to Azimuth From Start Point and type a value for the starting azimuth.

   This is the angle that defines the orientation of the procedure leg. The default unit is degrees.

ヒント:

You can right-click the parameter name and change the unit of measurement. If you change the unit of measurement after defining a value, the value is converted to the new unit of measurement, and you may need to redefine the value.

7. Click the cell next to Start Altitude and type a value.

   This is the starting height for the procedure leg. The default unit is Nautical Miles.

   You can right-click the parameter name and change the unit of measurement. If you change the unit of measurement after defining a value, the value is converted to the new unit of measurement, and you may need to redefine the value.

8. Click the cell next to End Altitude and type a value.

   This is the ending height for the procedure leg. The default unit is Nautical Miles.

   ヒント:

   You can right-click the parameter name and change the unit of measurement. If you change the unit of measurement after defining a value, the value is converted to the new unit of measurement, and you may need to redefine the value.

9. Click the cell next to Climb Rate and type the number of units you want to use for the progression from the starting altitude to the end altitude.

   This is the rate at which the altitude increases. The default unit is degrees.

   ヒント:

   You can right-click the parameter name and change the unit of measurement. If you change the unit of measurement after defining a value, the value is converted to the new unit of measurement, and you may need to redefine the value.

10. If necessary, click the cell next to MagVar Value and type a value for the magnetic variation.

    This can be a specified value or from a field defined in the MagVar Source parameter. The default unit is degrees.

You can right-click the parameter name and change the unit of measurement. If you change the unit of measurement after defining a value, the value is converted to the new unit of measurement, and you may need to redefine the value.

11. If necessary, click the drop-down arrow next to MagVar Source and choose a source for the magnetic variation.

    This is the source of the magnetic variation value.

12. If necessary, click the drop-down arrow next to MagVar Year and choose a different year for the World Magnetic Model.

    This is the year associated with the magnetic variation value.

    注意:

    You can only choose a value for MagVar Year if Magnetic Model is selected for the MagVar Source property.

13. Click the Execute button .

A line and a point are created.

ヒント:

If the segment and endpoint do not appear, click the Add Scratch Data Layers button at the top of the Feature Builder window.
