A chopper, commonly known as a helicopter, is a type of aircraft that uses rotating blades to lift off the ground and fly. Unlike fixed-wing airplanes, helicopters can take off and land vertically, making them useful for various applications, including search and rescue, medical transport, and military operations. Helicopters are equipped with a main rotor for lift and a tail rotor for stability and control. They can hover in place, fly backward, and maneuver in tight spaces, which makes them ideal for reaching remote areas or conducting aerial surveys. Their versatility is enhanced by the ability to carry different types of equipment and personnel.
