A remote pilot monitors manned-aircraft radio traffic near a non-towered airport but never transmits. Is the remote pilot violating a Part 107 communication requirement?

Why: The FAA study guide states that "a remote pilot-in-command is not required to communicate with manned aircraft when in the vicinity of a non-towered airport" and that "the remote pilot should refrain from transmitting over any active aviation frequency unless there is an emergency situation."

• Invents a self-announce mandate for remote pilots; the source explicitly says remote pilots are not required to communicate and should refrain from transmitting absent an emergency.
• Invents an FCC permit requirement that has no basis in the source material covering remote pilot radio use.
