The ExportAixm51 function must be configured to support AirspaceActivation objects.

Solución alternativa

Navigate to C:\Program Files (x86)\ArcGIS\AviationCharting\Desktop10.7\DataExchange\AIXM\Exporter\51

Edit the 51ExportTemplate.xml file to add gml:id and to source activity_code from the timeseheet.

Search for the following code:

<aixm:activation>

           <aixm:AirspaceActivation>

             <aixm:activity>{activity_code}</aixm:activity>

           </aixm:AirspaceActivation>

         </aixm:activation>

Replace the code above with the following:

<aixm:activation>

      <aixm:AirspaceActivation removeIfOnlyAttributes="true" gml:id="asact_{timesheet.clientkey_id}">

       <aixm:activity>{timesheet.activity_code}</aixm:activity>

      </aixm:AirspaceActivation>

     </aixm:activation>

In the same directory, edit the 51ExportRelationships.json file, and add the following lines under the 'timesheet' header, within the "airspace" section (line 476):

"timesheet.activity_code",

"timesheet.clientkey_id"

Add a comma at the end of line 475 ("timesheet.combtil_code",)  as it is no longer the final statement in the fields section.
