Where must a small unmanned aircraft’s serial number be listed when using either standard remote identification or a broadcast module?
A. The aircraft’s Document of Compliance.
B. The manufacturer’s Method of Compliance.
C. The Certificate of Aircraft Registration.
Answer: C. The Certificate of Aircraft Registration.
The Remote ID serial number, of the aircraft or of the broadcast module, goes on your registration in DroneZone and appears on the Certificate of Aircraft Registration. A declaration of compliance is the manufacturer's document, not yours, and for a broadcast module it lists the module's serial number, not the aircraft's, so it can't be the answer for both cases.
The FAA published this sample set in August 2021. Our answers were checked against the current regulations and against the testing-supplement figures in September 2026.
