Flying drones is fun, but not if you break federal law. The Federal Aviation Administration’s B4UFLY App provided through a partnership between the FAA and Aloft makes understanding air space restrictions and safe flying simple: Just tap the map and search for a location. At a glance it tells pilots whether they’re clear for take-off, should use caution, or need to stay on the ground.

Aloft uploads flight restrictions and uses Mapbox to turn them into clearly defined and searchable color-coded polygons.

After updating B4UFLY using Mapbox tools, Kittyhawk saw a substantially improved user experience, bringing their iOS app rating from 1.5 to 4.2.
