The FAA's proposed rules offer some promise for drone farmhands, and some limitations. As proposed, the rules require pilots to fly only within their line of sight, which limits how far drones can travel. A restriction on night flying would prevent anyone flying light-shining drones over crops after dark. Limitations on autonomy or pre-programmed flights also undermine using drones in a labor-saving way. Until the official rules come out, companies that want to test their crop-scanning drones either have to apply for a specific exemption from the FAA, pose as hobbyists, or operate in a legal gray area.
