New Drone Laws New Federal laws around how businesses pilot drones start today—requiring that pilots now pass flying lessons, much like a driving test. The first exams are starting today at 8 am ET, and are being administered by the Federal Aviation Administration (FAA) which says that more than 3,000 people had already signed up for the test in advance. Businesses that use drones include real estate firms, farms checking on crop maintenance, motion picture studios and a myriad other groups from firefighters to pipeline inspectors. Other rules around commercial drone flights that start today include keeping drones flying lower than 400 feet, weighing less than 55 pounds—and always staying in eyesight of the person who is operating them.
