The U.S. Federal Aviation Administration has proposed a framework of regulations that would allow routine use of certain small unmanned aircraft systems (UAS) in today’s aviation system. The FAA proposal offers safety rules for small UAS (under 55 pounds) conducting non-recreational operations. The rule would limit flights to daylight and visual-line-of-sight operations. It also addresses height restrictions, operator certification, optional use of a visual observer, aircraft registration and marking, and operational limits.

The proposed rule also includes extensive discussion of the possibility of an additional, more flexible framework for "micro" UAS under 4.4 pounds. The FAA is asking the public to comment on this possible classification to determine whether it should include this option as part of a final rule. The FAA is also asking for comment about how the agency can further leverage the UAS test site program and an upcoming UAS Center of Excellence to further spur innovation at "innovation zones."

The public will be able to comment on the proposed regulation for 60 days from the date of publication in the Federal Register, which can be found at www.regulations.gov.

The proposed rule would require an operator to maintain visual line of sight of a small UAS. The rule would allow, but not require, an operator to work with a visual observer who would maintain constant visual contact with the aircraft. The operator would still need to be able to see the UAS with unaided vision (except for glasses). The FAA is asking for comments on whether the rules should permit operations beyond line of sight, and if so, what the appropriate limits should be.

Under the proposed rule, the person actually flying a small UAS would be an "operator." An operator 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 (i.e., a private pilot license or medical rating).

The new rule also proposes operating limitations designed to minimize risks to other aircraft and people and property on the ground:

• A small UAS operator must always see and avoid manned aircraft. If there is a risk of collision, the UAS operator must be the first to maneuver away.
• The operator must discontinue the flight when continuing would pose a hazard to other aircraft, people or property.
• A small UAS operator must assess weather conditions, airspace restrictions and the location of people to lessen risks if he or she loses control of the UAS.
• A small UAS may not fly over people, except those directly involved with the flight.
• Flights should be limited to 500 feet altitude and no faster than 100 mph.
• Operators must stay out of airport flight paths and restricted airspace areas, and obey any FAA Temporary Flight Restrictions (TFRs).

The proposed rule maintains the existing prohibition against operating in a careless or reckless manner. It also would bar an operator from allowing any object to be dropped from the UAS.

Operators would be responsible for ensuring an aircraft is safe before flying, but the FAA is not proposing that small UAS comply with current agency airworthiness standards or aircraft certification. For example, an operator would have to perform a preflight inspection that includes checking the communications link between the control station and the UAS. Small UAS with FAA-certificated components also could be subject to agency airworthiness directives.
