An example of zoom climb and zoom ceiling.
i. An abnormally steep climb in which speed is traded for height. This is carried out near the ground by aircraft flying at very high speeds. Zoom maneuvers are normally carried out by aircraft with a high-thrust weight ratio.
ii. A technique of a high-performance aircraft climbing steeply at a high altitude at an optimized speed. The aircraft normally accelerates to the maximum level Mach number, trades speed for height, and reaches to an exceptional height far above the sustained ceiling level. The speed at that height is still very high, unlike a zoom at low altitudes. The altitude thus achieved is called a zoom ceiling.

zoom

(graphics)
To show a smaller area of an image at a higher magnification ("zoom in") or a larger area at a lower magnification ("zoom out"), as though using a zoom lense on a camera.

Unlike in an optical system, zooming in on a computer image does not necessarily increase the amount of detail displayed since this is limited by what is actually stored in the image. Similarly, you cannot zoom out beyond the full size of the image.

zoom

To change from a close-up view to a distant view (zoom out) or from a distant view to a close-up view (zoom in). An application may provide fixed or variable levels of zoom, and a graphics card may also have built-in zoom capability. All cameras have some zoom capability (see optical zoom and digital zoom).
