B4UFLY is a free iPhone app developed by the Federal Aviation Administration (FAA) in partnership with Aloft (formerly Kittyhawk). It is a valuable tool for drone operators to ensure they are aware of airspace and local advisories before flying. By using B4UFLY, drone operators can contribute to safer national airspace and stay compliant with regulations.

The app allows users to easily check the status of airspace and surrounding advisories by selecting their desired flying location. With just a few taps, drone operators can access important information about the airspace, including any restrictions or advisories in place. This helps them make informed decisions and fly responsibly.

B4UFLY also offers new crowdsourcing functionality, allowing users to contribute to the global advisory and compliance database. Users can flag areas for review and submit new locations for addition to the B4UFLY advisories directly within the app. This feature encourages collaboration and helps keep the database up to date with the latest information.

For any general questions or comments about unmanned aircraft systems (UAS) or drones, users can contact the FAA via email at or by calling 844-FLY-MY-UAbetween 8am and 4pm ET, Monday to Friday.
