Which trio represents valid aircraft certification categories?

• A. Normal, Utility, Acrobatic
• B. Normal, Experimental, Transport
• C. Utility, Light, Heavy
• D. Acrobatic, Commercial, Private

Answer: (A)

The key idea here is that aircraft are certified in distinct categories that define the allowed flight characteristics and structural requirements. For standard certificated airplanes, the main categories are Normal, Utility, Acrobatic, and Transport.

The trio that fits best is Normal, Utility, Acrobatic. These are three of the official certification categories used for many certificated aircraft, representing a progressive range of flight envelope and maneuvers from normal operation to more advanced aerobatics. The other options mix terms that aren’t official categories or include Experimental, which is a separate certification path rather than one of the standard categories. Light, Heavy, Commercial, and Private aren’t the official trio of certification categories, and while Transport is a valid category, it’s not one of the three named here.
