pertaining to air

a combination of aeronautics and space

relating to the forces of air in motion

the science of flight within the atmosphere

place on either land or water where aircraft can land and take off for flight

an aircraft that is kept aloft by the aerodynamic forces upon its wings and is thrust forward by a means of propulsion

a mixture of gases that contains approximately 78% nitrogen, 21% oxygen, and 1% other gases

a component, such as a wing, that is specifically designed to produce lift, thrust, or directional stability

any machine that is capable of flying through the air; included are ultralights, airplanes, gliders, balloons, helicopters, hangliders, and parasails

– height above sea level or ground level expressed in units

– a person who operates an aircraft in flight

– the art, science, and technology of flight within the atmosphere

– the upward movement of air ahead of the wing in flight

a force which slows the forward movement of an aircraft in flight

– the force which moves an aircraft forward in flight

– the natural force pulling everything to Earth

– the upward force that opposes gravity and supports the weight of an aircraft

– the curved part of an airfoil from its leading to trailing edge

– the downward movement of air behind a wing in flight

a spinning column of air that is created behind the wingtip as a result of air moving from an area of high pressure on the bottom to an area of low pressure on top

– a line drawn through an airfoil from its leading to trailing edge
