A remote pilot wants to improve their awareness of nearby manned air traffic. Which approach is consistent with Part 107?

Why →ADS-B 'In' is a receive-only function that lets the operator see traffic that is broadcasting its position; using it for situational awareness is permitted and useful. ADS-B 'Out' is the transmit function, and Part 107 prohibits transmitting it without FAA authorization. Distinguishing receiving from transmitting is the key to these questions.

The trap →The encouraged-Out option restates the very practice the rule forbids. The same-system option erases the In versus Out distinction; receiving traffic is fine, transmitting drone position is not, and neither is mandated equipment under Part 107.

Field note →Split the acronym: In means listening, Out means talking. Drones may listen for traffic but must stay silent on ADS-B Out unless authorized.
