- Aerial cartography — A technique and specialized branch of cartography dealing with the compilation, surveying, and correction of maps or topographic plans based on stereoscopic aerial photographs and photogrammetric data obtained from airplanes, helicopters, or drones. This modern process allows precise measurement of terrain relief and ground details, optimizing cadastre, urban planning, and environmental monitoring.
- Aerophotographic — Relating to aerophotography, concerning aerial photography; executed through airborne photography from airplanes, helicopters, or drones. It refers to optical equipment, techniques, flight crafts, or mapping materials used in the process of capturing high-altitude images for military, geodetic, or journalistic purposes.
- Aerial photogrammetry — A branch of photogrammetry dealing with determining the shape, dimensions, and position of objects on the Earth's surface, as well as with compiling topographical maps and plans based on measurements executed on aerial photograms. This technical discipline combines elements of optics, aviation, and computational mathematics.

- Aerogeology — A branch of applied geology that utilizes aerial photographs, satellite data, and multispectral images captured from above (from airplanes or drones) to study the geological structure of the Earth's crust, landforms, tectonic faults, and to locate mineral deposits or underground resources without initial ground intervention.
- Aeromodeller — A person who practices aeromodelling as a hobby, technical sport, or research activity; a specialist or enthusiast who designs, builds, adjusts, and flies scale model aircrafts (airplanes, gliders, helicopters). This activity involves applying advanced knowledge of aerodynamics, precision mechanics, electronics, and using lightweight composite materials to achieve optimal stability and high flight performance.
- Aerial vehicle — Any vehicle, complex technical apparatus, or aircraft structurally designed to navigate, sustain itself, and perform transport operations within Earth's atmosphere. This vast category encompasses both lighter-than-air craft (balloons, airships) and heavier-than-air craft (planes, helicopters, drones, air-cushion vehicles).
- Andronescu — A Romanian surname widespread nationally, representing a patronymic formed from the proper name Androne or Andron (derivatives of Andrew or the Greek Andronikos). Structurally, this name indicates descent from an ancestor bearing the mentioned root name, historically and currently borne by prominent figures in Romanian politics, academia, science, and culture.
- Anterotor — Rotating assembly located at the front of an aerial vehicle, propulsion system, or industrial equipment, having the primary role of generating initial thrust or absorbing fluid kinetic air mass. In specialized helicopters or advanced drones, this front rotor provides pitch control.
- Anti-aircraft — Designed for combating, intercepting, destroying, or neutralizing enemy aircraft, missiles, drones, or any other means of aerial attack; pertaining to airspace defense. It applies to military equipment like artillery, surface-to-air missile systems, and early-warning radars.
- Apilarnil — A natural, homogenized biological bee product obtained by trituration and filtration of the entire content of hive cells containing 7-day-old drone larvae (including the royal jelly and perilarval nutrients). Invented in Romania in 1980 by the apiarist Nicolae Ilieșiu, this nutrient complex is renowned for its energizing, biostimulating, and tonic properties, being rich in natural male hormones, amino acids, and vitamins.
- Self-balanced — Being in a state of stable equilibrium due to its own internal mechanisms or sensors; a device or vehicle capable of autonomously maintaining its correct orientation or structural stability.
