When you first load a logbook file, Route Browser scans all the records and looks for airports that it doesn’t recognize. Unknown airports occur because an airport shown in your logbook is not listed in the US or International airports list. The reasons for this include:
- The airport identifier has changed
- The airport has closed
- You entered an incorrect airport in your logbook
- You created your identifier for the airport
- The list of airports provided with Route Browser are out of date.
When your logbook contains unknown airports, a New Airports Wizard is presented to help you create new airport entries. These new entries are place in your “My Airports” list that will later be accessible through the Airports & Placemarks feature of product.
To create an airport entry for an unknown airport
- Click on the unknown airport in the list to the left of the dialog.
- If you think the airport has changed identifier, click on the Search Airnav Website button to view http://www.airnav.com. Enter the old identifier there to help you identify the new identifer.
- Enter the new airport identifier in the Existing Airport Identifier text box. This will fill in the correct Latitude and Longitude information.
- Press the Add button to add the new airport to your “My Airports” list.
- Repeat these steps for each identifier shown under Unknown Airports
TIP: An airport must have a latitude and longitude specified to display any associated routes on your map. Any route with an unknown airport will be ignored.
