A set of limits for the performance capabilities of some type of machine, originally used to refer to aircraft; - it is often described graphically as a two-dimensional graph of a function showing the maximum of one performance variable as a function of another.

It is used to refer to the maximum performance available at the current state of the technology, and therefore refers to a class of machines in general, not a specific machine.
