The drone pre-flight checklist automatically determines if you're within five miles of a major US airport and allows you to conduct a full pre-flight check
This app is structured to automatically capture your location and identify if you're within a five mile radius of a major US airport. If you're within a drone no-fly zone, the app will ask if you have received approval from the encroached air traffic controller (ATC). This app allows drone pilots and operators to conduct a thorough pre-flight inspection on a go / no-go basis. This app is completely customizable and can be tailored to any drone operator's needs.
### Turf, TopoJSON, and Mapbox Integration
This app was integrated to include [Turf](http://turfjs.org/) & [TopoJSON](https://github.com/mbostock/topojson) JavaScript libraries that utilize geospatial calculations within Fulcrum to display [Mapbox's](https://www.mapbox.com/drone/no-fly/) drone no-fly zone layer.
