Models are built to scale, defined as the ratio of any linear dimension of the model to the equivalent dimension on the full-size subject (called the "prototype"), expressed either as a ratio with a colon (ex. 1:8 scale), or as a fraction with a slash (1/8 scale). This designates that 1 inch (or centimeter) on the model represents 8 such units ...
Die-cast aircraft. A scale used for high-end model aircraft and very detailed paper and plastic model ships. 9 mm figure scale. Many airlines distribute models in this scale for free as a means of advertising. Aeroplane model brands in this scale include Flight Miniatures, JC Wings 200, Wings of Glory, and others.
A scale factor is usually a decimal which scales, or multiplies, some quantity. In the equation y = Cx, C is the scale factor for x. C is also the coefficient of x, and may be called the constant of proportionality of y to x. For example, doubling distances corresponds to a scale factor of two for distance, while cutting a cake in half results ...
In mathematics, a plane is a two-dimensional space or flat surface that extends indefinitely. A plane is the two-dimensional analogue of a point (zero dimensions), a line (one dimension) and three-dimensional space. When working exclusively in two-dimensional Euclidean space, the definite article is used, so the Euclidean plane refers to the ...
Articles related to scale models, physical models of an object that maintain accurate relationships between its important aspects, although absolute values of the original properties need not be preserved. This enables the model to demonstrate some behavior or property of the original object without examining the original object itself.

In geometry, shape excludes information about the object's position, size, orientation and chirality. [1] A figure is a representation including both shape and size (as in, e.g., figure of the Earth). A plane shape or plane figure is constrained to lie on a plane, in contrast to solid 3D shapes.
Congress ordered the Federal Aviation Administration to establish minimum dimensions for airplane seats within a year when the agency's funding was renewed in October 2018. The FAA has yet to comply.
