• Frieze-making (attr.) — Pertaining to abageri (frieze-makers) or their trade; characteristic of coarse cloth manufacturing. In material culture and social anthropology studies, the term describes the techniques, workshops, and corporate standards of thick wool processing used in pre-industrial communities to produce traditional winter gear.
• Traditional clothier — A historical regional term used as a synonym for abager; a person who manufactured, tailored, or sold clothes made of aba. In the history of Balkan communities, abagii formed a distinct professional category, often organized into powerful guilds that controlled local coarse wool trade routes and interacted with monastic healthcare systems for blanket supplies.
• Pincushion — A small cushion, box, or specially made holder used for storing and holding sewing needles and pins in a household; pincushion. Within the context of traditional tailoring guilds and crafts, it represented an indispensable accessory often worn at the waist or integrated into the work kit.
• Pincushion — A traditional sewing accessory used for organizing work tools, appearing in two forms: either a small box or case made of wood, metal, or bone intended for holding needles and thread, or a small fabric cushion stuffed with wool or bran into which needles are stuck during work to keep them handy. The term is primarily found in the regional dialects of Moldavia and Transylvania.
• Small needle — Popular diminutive of the noun 'ac' (needle); a very small needle used in fine tailoring, traditional embroidery, or for the delicate pinning of clothing components. In a regional sense, the term can also describe a tiny sharp object resembling a needle, such as the thorns of certain plants or minuscule metallic elements in the structure of precision mechanisms.
• Air ambulance — An aircraft (helicopter or airplane) specially equipped with emergency medical equipment and qualified personnel, used for the rapid transport of critical patients or organs intended for transplantation. This airborne intensive care mobile unit enables life-saving operations in hard-to-reach areas, ensuring advanced medical care during flight.
• Amphibious aircraft — Capable of operating, taking off, landing, or moving with equal efficiency both in the air and on the surface of water or solid ground. As a noun, it designates a seaplane equipped with a retractable wheeled landing gear, allowing it to use terrestrial airfields as easily as natural water runways.
• Flying car — A hybrid experimental or conceptual vehicle designed to operate both as an automobile on public roads and as an aircraft on airways, utilizing foldable or retractable wings and a mixed propulsion system. This advanced technological concept aims to relieve terrestrial traffic congestion by integrating daily commuting into controlled airspace.
• Aerocompass — An aerial navigation instrument (gyroscopic, magnetic, or electronic compass) mounted on board aircraft, used for continuously determining and indicating the magnetic heading or flight direction of the aircraft relative to cardinal points.
• Aerodyne — Any aircraft heavier than air, whose support and lift in the Earth's atmosphere are provided exclusively by the dynamic forces exerted by air on its lifting surfaces (fixed wings or moving rotors) during travel. The classification includes airplanes, helicopters, gliders, and drones, representing the opposite of aerostats.
• Aerodyne — A general or historical technical term used to designate any aircraft heavier than air (such as airplanes, helicopters, or gliders), whose support and lift in the atmosphere are provided exclusively by aerodynamic forces generated by the relative motion of its lifting surfaces (wings, rotors) in contact with the airflow. It represents the opposite of aerostats (balloons, zeppelins), which float based on Archimedean buoyancy.
• Aerodynamic — Relating to aerodynamics, concerning the motion of air and gases relative to solid bodies; having a fluid and optimized geometric shape, specially designed to minimize the drag resistance opposed by air during movement. It is widely applied in the design of aircraft, high-speed vehicles, and high-performance sports equipment.
• Aerodrome craft — An archaic, rare, or conceptual technical term used to describe an experimental heavier-than-air aircraft, an early prototype of a self-propelled airplane, or a covered dome-shaped structure designed for sheltering and protecting flight machines inside an airfield.
• Aerodrome — A defined area on land or water (including any buildings, installations, and equipment) intended to be used either wholly or in part for the arrival, departure, and surface movement of aircraft. Unlike a fully developed commercial airport, it may feature simplified infrastructure, often being utilized for sports aviation, utility flights, flight schools, or military operations.
• Aeroelasticity — A branch of mechanics and aerospace engineering that studies the interactions between aerodynamic forces, the elastic forces of a solid body's structure, and its inertial forces, while in relative motion. This field is crucial in the design of high-speed aircraft and suspended bridges to prevent destructive structural instability phenomena, such as flutter or buffeting.
• Avionics — A specialized branch of applied electronics and aeronautical engineering dealing with the design, manufacturing, installation, and maintenance of electronic systems and equipment used on board aircraft and rockets (navigation systems, communications, autopilot, radars, and cockpit sensors).
• Airbrake — A mobile aerodynamic device (retractable lifting surface, flap, or spoiler) mounted on the wings or fuselage of an aircraft or space vehicle, designed to be deployed into the airflow in order to increase drag resistance and rapidly reduce movement speed.
• Hovercraft — A self-propelled amphibious vehicle (hovercraft) capable of moving at a low altitude above water, land, swamps, or ice, by generating a continuous layer of compressed air beneath its hull (air cushion) which cancels its direct friction with the ground surface.
• Aeromechanics — A branch of fluid mechanics that studies the equilibrium and motion of air or other gases, as well as the mechanical behavior of solid bodies immersed in them or in relative motion to them. This major scientific field is structurally subdivided into aerostatics (the study of gases in equilibrium) and aerodynamics (the study of gases in motion).
• Aerometeorograph — A complex meteorological apparatus (recorder) specially designed to be mounted on board an airplane, aircraft meteorograph, or sounding balloon, used for the simultaneous graphic measurement and recording, on a rotating drum, of variations in barometric pressure, temperature, and humidity within the upper layers of the free atmosphere.
