As drone use grows, rules and regulations remain in flux and vary among jurisdictions. Last month, for instance, the Federal Aviation Administration granted operators of certain drones approval to fly them in controlled airspace in the US, but the UK has an outright ban on using them within a kilometer of airports. To help establish best practices, the International Organization for Standardization has released the first draft set of global standards for drone use. The draft does suggest no-fly zones around airports and other restricted areas, along with geofencing measures to keep drones away from sensitive locations. The standards also call for drone operators to respect others' privacy and a human intervention fail-safe for all flights.
