The FAA Gave the First Ever Go-Ahead For a Drone To Fly at an Airport (recode.net)
It's not legal to fly your drone anywhere near an airport -- at least not without a special waiver from the Federal Aviation Administration. From a report: For the first time under the FAA's commercial drone rules, the agency granted permission to operate a drone at an airport. Seven flights were conducted by Berkeley, Calif.-based 3D Robotics on Jan. 10 at Hartsfield-Jackson Atlanta International, the busiest airport in the world. Restrictions on flying drones near airports have to do with safety. Not only can drones collide with planes, but seeing one can also distract a pilot. The 3D Robotics drone was given permission to collect data on two four-story parking structures at the airport that a construction firm was hired to demolish.
The subheading in the linked article ("It's the first waiver granted for flight in Class B airspace since the FAA came up with commercial drone rules.") makes sense, but the summary, title, and article are a bit wonky.
It's been perfectly legal for a certified commercial Remote Pilot to fly at an airport since Part 103 went into effect, but only in Class G airspace. Small airports with Class E Surface or Class D airspace would require a waiver, and waivers have been had for those for a while now. Larger airports with Class C airspace took longer before the FAA began processing (and approving) waivers, but there had not been any waivers of Class B airspace. This is the first.
Of course, you can only get a waiver under Part 103, so if you're a hobby pilot, the five-mile rule is in effect. For Part 103 Remote Pilots, on the other hand, it's all about airspace. (Most of the FAA Knowledge Exam is airspace and weather.)
