Aeroplane vs. Plane

Aeroplanenoun

A powered heavier-than-air aircraft with fixed wings.

Aeroplanenoun

An airfoil.

Aeroplanenoun

(entomology) Any of various nymphalid butterflies, of various genera, having a slow gliding flight. Also called planes.

Aeroplanenoun

A light rigid plane used in aërial navigation to oppose sudden upward or downward movement in the air, as in gliding machines; specif., such a plane slightly inclined and driven forward as a lifting device in some flying machines. Also called airfoil.

Aeroplanenoun

hence, a heavier-than-air flying machine using such a device to provide lift. In a modern aeroplane, the airfoils are called the wings, and most of the lift is derived from these surfaces. In contrast to helicopters, the wings are fixed to the passenger compartment (airframe) and do not move relative to the frame; thus such a machine is called a fixed-wing aircraft. These machines are called monoplanes, biplanes, triplanes, or quadruplanes, according to the number of main supporting planes (wings) used in their construction. After 1940 few planes with more than one airfoil were constructed, and these are used by hobbyists or for special purposes. Being heavier than air they depend for their levitation on motion imparted by the thrust from either propellers driven by an engine, or, in a jet plane, by the reaction from a high-velocity stream of gases expelled rearward from a jet engine. They start from the ground by a run on small wheels or runners, and are guided by a steering apparatus consisting of horizontal and vertical movable planes, which usually form part of the wings or tail. There are many varieties of form and construction, which in some cases are known by the names of their inventors. In U.S., an aeroplane is usually called an airplane or plane.

Aeroplanenoun

an aircraft that has a fixed wing and is powered by propellers or jets;

Aeroplanenoun

a powered flying vehicle with fixed wings and a weight greater than that of the air it displaces.

Planeadjective

Of a surface: flat or level.

Planenoun

A level or flat surface.

Planenoun

(geometry) A flat surface extending infinitely in all directions (e.g. horizontal or vertical plane).

Planenoun

A level of existence or development. (eg, astral plane)

Planenoun

A roughly flat, thin, often moveable structure used to create lateral force by the flow of air or water over its surface, found on aircraft, submarines, etc.

Planenoun

Any of a number of designated ranges of sequential code points.

Planenoun

(anatomy) An imaginary plane which divides the body into two portions.

Planenoun

(countable) A tool for smoothing wood by removing thin layers from the surface.

Planenoun

An airplane; an aeroplane.

Planenoun

(countable) A deciduous tree of the genus Platanus.

Planenoun

(Northern UK) A sycamore.

Planeverb

(transitive) To smooth (wood) with a plane.

Planeverb

(nautical) To move in a way that lifts the bow of a boat out of the water.

Planeverb

To glide or soar.

Planenoun

Any tree of the genus Platanus.

Planenoun

A surface, real or imaginary, in which, if any two points are taken, the straight line which joins them lies wholly in that surface; or a surface, any section of which by a like surface is a straight line; a surface without curvature.

Planenoun

An ideal surface, conceived as coinciding with, or containing, some designated astronomical line, circle, or other curve; as, the plane of an orbit; the plane of the ecliptic, or of the equator.

Planenoun

A block or plate having a perfectly flat surface, used as a standard of flatness; a surface plate.

Planenoun

A tool for smoothing boards or other surfaces of wood, for forming moldings, etc. It consists of a smooth-soled stock, usually of wood, from the under side or face of which projects slightly the steel cutting edge of a chisel, called the iron, which inclines backward, with an apperture in front for the escape of shavings; as, the jack plane; the smoothing plane; the molding plane, etc.

Planeadjective

Without elevations or depressions; even; level; flat; lying in, or constituting, a plane; as, a plane surface.

Planeverb

To make smooth; to level; to pare off the inequalities of the surface of, as of a board or other piece of wood, by the use of a plane; as, to plane a plank.

Planeverb

To efface or remove.

Planeverb

Figuratively, to make plain or smooth.

Planeverb

Of a boat, to lift more or less out of the water while in motion, after the manner of a hydroplane; to hydroplane.

Planenoun

an aircraft that has a fixed wing and is powered by propellers or jets;

Planenoun

(mathematics) an unbounded two-dimensional shape;

Planenoun

a level of existence or development;

Planenoun

a power tool for smoothing or shaping wood

Planenoun

a carpenter's hand tool with an adjustable blade for smoothing or shaping wood;

Planeverb

cut or remove with or as if with a plane;

Planeverb

travel on the surface of water

Planeverb

make even or smooth, with or as with a carpenter's plane;

Planeadjective
