What are the three categories of aircraft recognized by the FAA?

The three categories of aircraft recognized by the FAA are airplane, rotorcraft, and lighter-than-air. This classification is essential for regulatory purposes as it helps in determining the specific regulations, requirements, and standards applicable to different types of aircraft operations.

Airplanes are fixed-wing aircraft that derive lift from their wings, while rotorcraft includes helicopters and other aircraft that use rotating blades to create lift. Lighter-than-air aircraft, such as balloons and airships, rely on buoyancy to achieve flight. This categorization by the FAA is fundamental for maintaining safety standards and ensuring that pilots are trained and certified appropriately for the aircraft they operate.

In contrast, the other options provided do not encompass the recognized categories completely or accurately. While drones and other variations of aircraft do exist, they fall under broader categories rather than being standalone classifications. The mention of jet and turbo-prop aircraft also limits the scope to specific types of airplanes rather than the broader category. Moreover, helicopter, biplane, and seaplane represent specific variations or designs within the broader categories of rotorcraft and airplanes, rather than primary classifications.
