Which are considered categories of aircraft for certification?

The categories of aircraft for certification are standardized classifications that help define the intended use and operational limitations for different types of aircraft. Normal, utility, and acrobatic refer specifically to the design and intended operations of the aircraft.

Normal category aircraft are intended for general aviation purposes, allowing for a wide range of operations with specific design standards for safety and usability. Utility category aircraft are designed with more robust structures to accommodate maneuvers typical in flight training and other operational uses. Acrobatic category aircraft can perform aerobatic maneuvers and meet the necessary design requirements for safety during such operations.

The other choices do not fit within the established categories recognized by aviation regulatory authorities. For example, commercial and military refer more to operational roles rather than design categories, while terms like passenger and cargo pertain to the aircraft's function rather than a regulatory classification. Light sport and amphibious aircraft represent specific types of aircraft but do not encompass the broader categorization framework.
