Which of the following is NOT one of the three drone operator classes?

• A. Public
• B. Civil
• C. Model
• D. Commercial

Answer: (D)

The concept being tested is how drone operators are categorized by who is flying and for what purpose. The three recognized classes are public, civil, and model aircraft. Public operations are conducted by government entities, civil operations are carried out by non-government individuals or organizations, and model aircraft are flown for recreation under hobbyist guidelines. The term commercial describes the purpose of the operation, not a separate operator class. Commercial activities are typically handled within the civil category under applicable regulations, rather than forming its own distinct class. So the option that represents “commercial” isn’t one of the three operator classes.
