Powered planes are aircraft that use engines to generate thrust, allowing them to fly. These engines can be either jet engines or propellers, and they provide the necessary power to lift the plane off the ground and keep it in the air. Powered planes are commonly used for commercial flights, cargo transport, and military operations. Unlike gliders, which rely on air currents and gravity to stay aloft, powered planes can travel long distances and reach higher altitudes. They are essential for modern transportation, connecting people and goods across vast distances. Examples of powered planes include Boeing 747 and Cessna 172.
