Digital Obstacle File Online app for iPhone and iPad

The Digital Obstacle File Online app allows users perform geographic searches of FAA Digital Obstacle File data within the US. Limited coverage for Canada, Mexico, the Pacific and the Caribbean is also available. Users can search for obstacles simply zooming to a location on the map.

The app utilizes a credit-based system and includes a limited amount of free credits. Each search that returns data costs 1 credit. Searches that return no data or results over the system limit do not use any credits. After the initial credits are used, additional credits can be purchased within the app.

*Note: This app should not be used for flight planning.
