Creating an MSA element
The MSA Element tool creates an Minimum Safe Altitude (MSA) element in the chart layout view. The MSA indicates the minimum safe altitude that provides a 1,000-foot obstacle clearance at a specific distance from the Navaid, airport, waypoint, or other significant point, at the center of the MSA element.
The MSA Element tool draws the MSA values directly from the production database, allowing the generation of a customizable element. The individual components of the MSA element (inbound bearings, navaid, and associated text) are stored in the MSA, MSAGROUP, NavaidSystem_C, or DesignatedPoint_C feature classes in the production database.
- Start ArcMap.ヒント:
If the ArcMap - Getting Started dialog box appears, you can open a new or existing map document. You can also check the Do not show this dialog box in the future check box and click Open.
- Ensure that the correct product library and production database are set in the Data Management pane on the Production Properties dialog box.
- Ensure that your chart's data frame is set to the appropriate
instance by right-clicking the data frame, selecting Properties,
and clicking the Product Library tab.
- Click OK.
- Ensure that there is a definition query that identifies the
procedure on which the MSA is needed on the TERMINALPROCEDURE table.
- Add the TERMINALPROCEDURE table to the Table Of Contents window if
it is not already present. ヒント:
To view the stand-alone tables already in the Table Of Contents window, click the List By Source button at the top of the Table Of Contents window.
- If there is not already a record in the TERMINALPROCEDURE table for
the procedure, create a new record.
The definition query should resemble the following query (with only the GFID differing from the example):
GFID = '{24B739EE-A16E-49BA-A309-FC5AE6B939C1}'
- Add the TERMINALPROCEDURE table to the Table Of Contents window if
it is not already present.
- On the main menu, click View → Layout View.
- On the main menu, click Customize → Toolbars → Aeronautical Terminal Procedures.
- Click the MSA Element button .
An MSA element is created.
メモ:Errors are encountered when there is an invalid or missing parameter. A warning indicates the missing value and field/table where the value resides.
- Select the MSA and move it to the appropriate location on the
chart.ヒント:
If information on the procedure where the MSA resides changes, and that information affects the MSA, you can regenerate it by clicking the MSA Element tool again.
