- Model aircraft — A small-scale aircraft built as a miniature replica of a real plane or based on an original design, capable or incapable of flight, used for sporting, recreational, educational, or experimental purposes. Flight-capable model aircraft can be radio-controlled, control-line operated, or free-flying, and are built from lightweight materials such as balsa wood, polystyrene, or carbon fiber.
- Aircraft — Any technical apparatus capable of sustaining itself in the atmosphere and moving through airspace due to the reactions of the air, other than its reactions against the earth's surface. This vast category structurally includes both aircraft lighter than air, such as balloons and airships, and aircraft heavier than air, such as airplanes, helicopters, and gliders.
- Aeroplane — A historical or archaic name given to early generation airplanes; a flying machine heavier than air, propelled by an engine and sustained in the atmosphere by the lift force of fixed wings. Although almost completely replaced by 'avion' in modern technical language, it retains strong documentary and literary value linked to aviation pioneering.
- Aeroplanist — A historical or archaic name given to an airplane pilot or aviator, especially during the pioneering era of aeronautics; a person who operated or navigated an aeroplane. This structural term highlights the direct connection of flying personnel with early fixed-wing aircraft, being later completely replaced by the universal term 'pilot'.
- Wingspan — The linear distance between the tips of the open wings of a bird or an airplane; (figurative sense) scope, scale, major importance, complexity, or outstanding intellectual capacity of an action, a project, or a remarkable personality.
- Aeroplane — An early popular, archaic, or etymologically incorrect form for the term 'aeroplan' (airplane); an aircraft heavier than air, equipped with fixed wings and propelled by an engine, designed for air transport. Widely used in colloquial language at the beginning of the 20th century, the word reflects a structural phase of linguistic transition during the assimilation of the first aviation technical terms.
- Airplane — An aircraft heavier than air, equipped with fixed wings that generate aerodynamic lift and propelled by one or more piston, turbojet, or turboprop engines. This means of air transport is destined for the rapid displacement of passengers, cargo, or the execution of special military and civil missions within the lower layers of the Earth's atmosphere.
- Light aircraft — A small motorized aircraft with a limited maximum takeoff weight and a restricted transport capacity, intended primarily for pleasure flights, flight schools, utility purposes, or short-distance private travel. This type of aircraft is usually equipped with piston engines and propellers, offering the advantage of operating from small airfields or unpaved runways.
- Aeroplane — A historical, archaic, or literary term used in the early stages of aeronautics to name an aeroplane, an airplane, or a mechanically propelled fixed-wing flight apparatus. This compound word reflects a period of linguistic transition when technical names were not fully stabilized, being used in old maps, early patents, or press articles from the beginning of the 20th century.
- Avtolet — An archaic or regional hybrid term, used ephemerally in the first half of the 20th century (influenced by Slavic/Russian terminology), to designate an airplane, aircraft, or self-propelled flying machine. It represents an early linguistic attempt to name aerial vehicles, combining the Greek element 'avto' (self) with the Slavic root 'let' (to fly), quickly eliminated by the French-derived neologism 'avion'.
