Which of the following is the correct registration weight for the lightest drone?

The correct registration weight for the lightest drone is 0.55 lbs. This is important because the Federal Aviation Administration (FAA) has specific weight thresholds that determine the registration requirements for unmanned aircraft. A drone that weighs less than 0.55 lbs is considered a "miniature unmanned aircraft" and does not require FAA registration. It’s essential for drone operators to be aware of these weight limits to ensure compliance with regulations. Incorrectly identifying the lightest weight can lead to misunderstandings regarding registration and operational rules.
