B4UFLY is an easy-to-use smartphone app that helps unmanned aircraft operators determine whether there are any restrictions or requirements in effect at the location where they want to fly.
Key features include:
A clear "status" indicator that immediately informs the operator about the current or planned location. For example, it shows flying in the Special Flight Rules Area around Washington, D.C. (No Drone Zone) is prohibited.
Information on the parameters that drive the status indicator
A "Planner Mode" for future flights in different locations
Informative, interactive maps with filtering options
