How to use B4UFLY app. Fly your drone in the United States

B4UFLY (App Store) is an application that allows you to check on the map the no-fly zone of drones in the United States. If you plan to fly drones in the United States, install them in advance.
In the United States and other countries, there are differences in the rules depending on whether takeoff weight is 250g or more. However, the only difference between a drone weighing less than 250g and a heavier drone in the United States is aircraft registration requirement. Please note that other flight rules apply to drones of all weights.
Please refer to the Drone flight rule page for drone flight rules in each country, including the United States.
