When may a remote pilot reduce the intensity of an aircraft's lights during a night flight?
A
At no time may the lights of an sUAS be reduced in intensity at night.
B
When a manned aircraft is in the vicinity of the sUAS.
C
When it is in the interest of safety to dim the aircraft's lights.✓ Correct Answer
Explanation
14 CFR 107.29(a)(2) requires night operations to use anti-collision lighting visible for at least 3 statute miles, but allows the remote PIC to reduce its intensity (never turn it off) if he or she determines that, because of operating conditions, it would be in the interest of safety to do so. The rule contains no blanket ban on dimming and does not tie dimming to nearby manned aircraft.
