        Defining Aircraft Substitutions
    </title>
    <para>
        When creating a BaseOps case, you may need aircraft that are not
        present in the standard aircraft library. To handle this situation,
        BaseOps allows you to define <termtext>aircraft substitutions</termtext>,
        which associate new aircraft names with equivalent proxy aircraft
        that are in the library.
    </para>
    <para>
        Once the substitutions are defined, the new aircraft can be used
        throughout the BaseOps case. However, when the noise models are
        run, the substitution aircraft are used.
    </para>
    <para>
        To define aircraft substitutions, choose Aircraft Substitutions
        from the <link target='#BaseOps_ListPane_id'>object type selector
        dropdown list</link>. Substitutions can be added, duplicated,
        and deleted as described in <iref
        target='BaseOps_ListPane_id'/>.
    </para>
    <para>
        To edit an aircraft substitution, first select it in the <link
        target='#BaseOps_ListPane_id'>object list</link>, then edit its
        properties in the <link
        target='#WCF_ApplicationMainWindow_id'>text pane</link>.

        Aircraft substitutions have the following properties.

            <para>
                <italic>New Aircraft Name</italic> - The name of the new, non-BaseOps
                aircraft you are defining. While there is no limit on the name's
                length, you should keep it as short as possible.

                library aircraft that will act as a substitute for the new aircraft.
