A "fixed-wing" aircraft is a type of airplane that has wings that do not move or change position during flight. These wings are designed to generate lift, allowing the aircraft to fly. Fixed-wing aircraft can vary in size and purpose, from small private planes to large commercial airliners like the Boeing 747. Unlike rotorcraft, such as helicopters, which use rotating blades for lift, fixed-wing aircraft rely on the forward motion created by engines. This design makes them efficient for long-distance travel and capable of carrying heavier loads compared to other types of aircraft.
