The avionics - a portmanteau word consisting of aviation (from Latin avis = bird) and electronics - is a term used in aviation and space technology, and is the sum of the electrical and electronic equipment on board an aircraft, including flight instruments. Exceptions to this are in the language, however, electronic applications in cabin systems. The term avionics (English Avionics ) was coined in the U.S. and about in the 1960s.
In modern aircraft are plenty of other computers and devices in use. Usually the devices in a specific area below the cabin floor or in the vicinity of the cockpit are combined, the Avionics Compartment (also Avionics Bay). In order to reduce the increasing number of necessary computer and control units, beginning of 2000 the principle of " Integrated Modular Avionics " was developed (IMA ).
