Small aircraft are lightweight planes designed for personal, recreational, or business use. They typically have a seating capacity of up to six passengers and are often used for short-distance travel. Examples of small aircraft include Cessna 172 and Piper PA-28, which are popular among private pilots. These aircraft can be powered by either piston engines or turboprop engines, depending on their design and purpose. Small aircraft are commonly used for flight training, aerial photography, and agricultural applications, making them versatile tools in aviation.
