The FAA registration number is required to be displayed

• A. on the outside surface of the drone
• B. on the battery
• C. on the controller
• D. in the user manual

Answer: (A)

Registration numbers give a unique ID to the aircraft so it can be identified by authorities and others who might encounter it. To make that ID reliable, it must be displayed on the outside surface of the drone itself where it’s visible during flight and after landing. Placing it on the battery, the controller, or in the manual wouldn’t guarantee visibility or stay with the aircraft in use, so those locations aren’t appropriate. The mark should be legible and durable so it remains readable in normal conditions.
