Under Part 107, when may a remote pilot operate a small unmanned aircraft that is transmitting ADS-B Out?
AOnly when authorized by the FAA; routine Part 107 operations may not transmit ADS-B Out✓
BAny time, because ADS-B Out makes the drone more visible to other aircraft
COnly during operations conducted at night
Why →Part 107 prohibits operating a small UAS with ADS-B Out equipment in transmit mode unless the operator is otherwise authorized by the FAA. This is the opposite of the instinct that more broadcasting equipment is always safer. Drones must not transmit ADS-B Out in normal operations.
The trap →The any-time option relies on the reasonable-sounding but wrong idea that broadcasting position always improves safety. The night-only option invents a condition the rule does not contain; the restriction has nothing to do with time of day.
Field note →Remember the rule as a prohibition, not a permission: the default for a Part 107 drone is ADS-B Out off. Authorization is the rare exception, not the norm.
