Where should the FAA registration number be displayed on the UAS?

• A. On the outside of the UAS in a location that is easily readable.
• B. Inside the battery compartment.
• C. On the controller only.
• D. Engraved on the propeller.

Answer: (A)

The registration number must be displayed on the outside of the UAS in a location that is easily readable during normal operation. This makes the aircraft quickly identifiable by authorities and others who need to read it without disassembling anything. Putting the number inside a battery compartment hides it from view, and placing it only on the controller or engraving it on a propeller won’t meet the requirement because the ID needs to be on the UAS itself and easily read in day-to-day use.
