• 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.
• 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.
• 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.
• Marinization — The act of marinizing or adapting to the sea and its result; the process of physical and psychological adaptation of a crew to sea life. In naval aviation, it denotes the structural adaptation of an aircraft or equipment to be safely operated aboard vessels through anti-corrosive protection.
• Wings — The plural form of the noun 'aripă'; paired locomotion organs used for flight by birds, insects, and some mammals (bats); lateral structural components of an aircraft that generate the lift force required to sustain it in the air; lateral elements of a vehicle's bodywork covering the wheels.
• Aerial duster — A specialized apparatus, device, or utility aircraft structurally configured for the aerial scattering of pesticides, insecticides, or fertilizers in the form of powder or fine dust over agricultural crops or forestry massifs. This technical system optimizes plant protection by uniformly dispersing solid chemical substances over large areas in a considerably reduced time.
• Aerial sprayer — A specialized apparatus, complex mechanical installation, or utility aircraft structurally configured for the application, dispersion, and fine spraying of liquid chemical substances (insecticides, fungicides, herbicides, or foliar fertilizers) over agricultural crops or forestry zones. This technical system uses a spray boom with calibrated nozzles mounted under the wings to ensure uniform and rapid coverage of the ground or vegetation.
