FAA Ground School Practice Test

What are the classes of aircraft according to certification of airmen?

1. Jet and turboprop

2. Single-engine land and sea, multiengine land and sea

3. Experimental and light-sport

4. Commercial and private

The correct answer is: Single-engine land and sea, multiengine land and sea

The classification of aircraft according to the certification of airmen is primarily focused on the design and operational characteristics of the aircraft. This classification divides them into types such as single-engine and multiengine, while also further breaking them down by their operational environments, specifically land and sea. This classification is crucial because it aligns directly with the types of pilot certifications: a pilot may be certified to operate single-engine aircraft on land, multi-engine aircraft on land, and similarly for sea-based operations. The other choices, while they do refer to categories of aircraft or pilot licensing, do not accurately represent the broad, structured classification system used for certifying airmen. For example, experimental and light-sport aircraft are specific categories but do not cover the full spectrum needed for airman certification across different operational environments. Jet and turboprop classifications, while relevant to types of propulsion systems, do not encompass the FAA's criteria for airman certification. Commercial and private refer to types of pilot licenses rather than classes of aircraft, which further emphasizes why the choice centered around single-engine and multiengine land and sea is the most appropriate.
