Etymology
The term "fixed-wing" is a modern technical compound, created in the early 20th century to categorize aircraft. The adjective "fixed" originates from the Latin verb figere, meaning 'to fasten or attach', conveying the concept of being securely attached and immobile relative to the aircraft's body. This is combined with "wing", a word of Old Norse origin that entered English and came to specifically denote the airfoils providing lift. The compound logically distinguishes this aviation technology from "rotary-wing" aircraft (like helicopters), where the wings (rotor blades) move. Thus, "fixed-wing" literally describes an aircraft with wings that are stationary and rigid, a defining characteristic of conventional airplanes.
Analysis
Structure: fixed (immobile) + wing (airfoil)
fixed: From Latin fixus (past participle of figere 'to fasten'), via Old French fix. In this compound, it functions as an adjective meaning 'fastened securely; not movable'.
wing: From Old Norse vængr (via Middle English winge), related to the concept of a limb for flight. In this compound, it functions as a noun denoting the specific airfoil of an aircraft.
Examples

Pilots must obtain different certifications to fly fixed-wing planes versus helicopters.
The development of fixed-wing drones has revolutionized aerial photography and surveying.
