What are the four basic components of unmanned aircraft?

• A. Wings, Fuselage, Landing Gear, Tail
• B. Engine, Propeller, Battery, and Camera
• C. Fuselage, Airfoil, Stabilizing and Control Surfaces, and Powerplants
• D. Hull, Keel, Rudder, Sail

Answer: (C)

Understanding the basic anatomy of an unmanned aircraft involves four essential parts. The fuselage is the main body that supports and houses everything else, including electronics and payload. The airfoil refers to the wing’s cross‑section, which is shaped to generate lift as air flows over it. Stabilizing and control surfaces, such as the tailplane and rudder, elevators, and ailerons, provide stability and control the aircraft’s attitude—pitch, roll, and yaw. Powerplants are the propulsion system that produces thrust, typically motors with propellers powered by a battery or other energy source. Together, these elements cover the structure, lift generation, flight control, and propulsion needed for flight. The other options either emphasize nonessential or nonuniversal parts (like a camera as a required component) or mix in features not central to how an unmanned aircraft is built.
