If you haven't already downloaded the database, find some Wi-Fi access (the file is about 11 MB) and select Menu -> Update Database. This will fetch the latest version of the database from our server and install it on your compact flash memory card. Remember, the OurAirports database is not certified, you must verify correctness of data from the database before using it for navigation.

On this screen, in addition to the update menu selection, are user interface items: Search for; Search Opt; a query data input field and the Execute Search button.

    • Name: Searches for facilities with a name that starts with the text in the data input field
    • Name Search: Searches for facilities with a name that contains the text in the data input field
    • Distance: if the navigation system has resolved your position within the last 10 minutes you will have the option of locating facilities within 60 nm of that location.
  • Data input field: prompts for the data needed for the search selected by Search Opt
  • Execute Search: performs the search and displays the results on the screen.
Once a search has successfully completed a list of returned facilities will be displayed in a list.

You may select one of the facilities from the list, and view more data on a facility screen.
