Is registration required for a UAS weighing 0.5 pounds?

• A. No.
• B. Yes.
• C. Only if used commercially.
• D. Only if it weighs more than 2 pounds.

Answer: (A)

Registration for small UAS is required based on the takeoff weight threshold: if the aircraft weighs more than 0.55 pounds (about 250 grams) including payload, it must be registered. A drone weighing 0.5 pounds is below that threshold, so registration is not required, whether you’re flying recreationally or commercially. The important point is the weight limit, not the purpose of the flight. If the weight were above 0.55 pounds, registration would be required regardless of use.
