The Federal Aviation Administration (FAA) has released proposed regulations for the commercial use of small, unmanned aerial vehicles (UAVs) or drones by industries including agriculture.

Technically called “unmanned aircraft systems” (UAS), the rules apply to small aircraft under 55 pounds and would limit their use to daylight and to visual line-of-sight operations, which could be a problem for agricultural operations.

The nearly 200 page proposal was apparently accidentally posted on the FAA website over the weekend. The FAA will be asking for comments on the proposed rules.
