At startup the app checks to see if there is new data to download.  (The data used comes from the FAA and is updated every 56 days.  Note the app only contains information about US airports.)

To use the app, simply type a location into the search bar.  The map will scroll to that location and display the airports in the vicinity.  The normal map functions - scroll and zoom - are available.

Tap an airport to view more information about it from AirNav.com.

Since there are almost 20,000 landing sites to select from, you may want to do some filtering.  The Filter screen provides a way to do this.

Planned enhancements:

1. •Driving directions between the selected location and airport.
