The FAA has published draft regulations covering the use of small unmanned aircraft systems (UAS).
The proposed rules cover small UAS (under 25kg) conducting non-recreational operations.
The rules would limit flights to daylight and line-of-sight operations, and address height restrictions, operator certification and aircraft registration.
The proposals also include discussion of the possibility of an additional, more flexible framework for micro UAS under 2.4kg.
Under the regulations, UAS operators would have to be at least 17 years old, pass an aeronautical knowledge test and obtain an FAA UAS operator certificate.
To maintain certification, the operator would have to pass the FAA knowledge tests every 24 months.
A small UAS operator would not need any further private pilot certifications.
The FAA is asking the public to comment on the proposed regulation.
“Technology is advancing at an unprecedented pace and this milestone allows federal regulations and the use of our national airspace to evolve to safely accommodate innovation,” said transport secretary, Anthony Foxx.
