The camera gives him a drone's-eye view and a map on the iPad screen shows where the drone is headed. Bowsher, owner of Eagle's View Aerial Photography, is among a growing number of drone pilots certified by the Federal Aviation Administration to operate commercially. New rules issued last summer by the FAA allow anyone at least 16 years old to earn a "remote pilot certificate" to fly drones for commercial use. [...] commercial operators had to be certified pilots — Bowsher maintains his private pilot's license for the business — and had to apply for an exemption to rules that limited drones to hobby use only. Both remote pilot certificate holders and pilots who received a commercial drone exemption must abide by FAA rules like those that require drones to stay within the pilot's line of sight and to get no farther than 400 feet from the ground or the top of a building. Drones also can't fly over anyone who isn't involved with the drone's activities, according to a summary of regulations posted to the FAA's website. Bowsher, who got his student pilot's license before he even had a driver's license, started his drone photography business after becoming restless in retirement. With his background in home sales, he decided to look into drone photography with an eye toward marketing the service to real estate firms.
