Section 107.29 Daylight operation. (a) No person may operate a small unmanned aircraft system during night. (b) No person may operate a small unmanned aircraft system during periods of civil twilight unless the small unmanned aircraft has lighted anti-collision lighting visible for at least 3 statute miles. The remote pilot in command may reduce the intensity of the anti-collision lighting if he or she determines that, because of operating conditions, it would be in the interest of safety to do so. (c) For purposes of paragraph (b) of this section, civil twilight refers to the following: (1) Except for Alaska, a period of time that begins 30 minutes before official sunrise and ends at official sunrise; (2) Except for Alaska, a period of time that begins at official sunset and ends 30 minutes after official sunset; and (3) In Alaska, the period of civil twilight as defined in the Air Almanac.

(c) The remote pilot in command, the person manipulating the flight controls of the small unmanned aircraft system, and the visual observer must coordinate to do the following: (1) Scan the airspace where the small unmanned aircraft is operating for any potential collision hazard; and (2) Maintain awareness of the position of the small unmanned aircraft through direct visual observation. Section 107.31 Visual line of sight aircraft operation. (a) With vision that is unaided by any device other than corrective lenses, the remote pilot in command, the visual observer (if one is used), and the person manipulating the flight control of the small unmanned aircraft system must be able to see the unmanned aircraft throughout the entire flight in order to: (1) Know the unmanned aircraft-s location; (2) Determine the unmanned aircraft-s attitude, altitude, and direction of flight; (3) Observe the airspace for other air traffic or hazards; and (4) Determine that the unmanned aircraft does not endanger the life or property of another. (b) Throughout the entire flight of the small unmanned aircraft, the abil- Section 107.35 Operation of multiple small unmanned aircraft.
