Synthetic vision system. A modern synthetic vision system produced by Honeywell. A synthetic vision system (SVS) is a computer-mediated reality system for aerial vehicles, that uses 3D to provide pilots with clear and intuitive means of understanding their flying environment.
Synthetic fiber. Synthetic fibers (British English: synthetic fibres) is the result of extensive research by scientists to improve on naturally occurring animal and plant fibres. In general, synthetic fibers are created by extruding fiber forming materials through spinnerets into air and water, forming a thread. Before synthetic fibres were developed, artificially manufactured fibres were made from polymers obtained from petrochemicals.
