The drones can be flown only during the day, only up to an altitude of 400 feet, at a speed of up to 100 miles per hour and they have to stay within visual contact of the operator. The devices can’t be flown over people who aren’t somehow related to the flight. Privacy guidelines for drone users were already published. The operator must be at least 16 years old. Pilots don’t necessarily need to have a license but they do have to pass a written test on aeronautical knowledge. The FAA had received about 3,000 requests for drone pilot certifications. Due to some other limitations it will still be a while before companies like Amazon can officially spin up on-demand drone deliveries. Not obeying the rules attracts punishment by FAA. The fine could be $1,100 or more.
