| Resumo: | Avionics refers to electronic systems on aircraft , artificial satellites , and spacecraft that provide communications , navigation and guidance, display systems, flight management systems, sensors and indicators, weather radars, electrical systems, and various computers onboard modern aircraft and spacecraft. It includes hundreds of systems fitted to aircraft to meet individual roles. These can be as simple as a search light for a police helicopter or as complicated as the tactical system for an airborne early warning platform. The word avionics is a combination of aviation and electronics. The term avionics was not in general use until the early 1970s.Up to this point instruments, radios, radar, fuel systems, engine controls, and radio navigation aids formed individual (and often mechanical) systems. In the 1970s, avionics was born, driven by military need rather than civil airliner development. Military aircraft had become flying sensor platforms, and making large amounts of electronic equipment work together had become the new challenge. Today, avionics as used in military aircraft almost always forms the biggest part of any development budget. Aircraft like the F-15E and the now retired F-14 have roughly 80 splits of 60 40 in favor of avionics, percent of their budget spent on avionics. Most modern helicopters now have budget The civilian market has also seen a growth in cost of avionics. Flight control systems (fly-by-wire) and new navigation needs brought on by tighter airspace, have pushed up development costs. The major change has been the recent boom in consumer flying. As more people begin to use planes as their primary method of transportation, more elaborate methods of controlling aircraft safely in these high restrictive airspace have been invented. With the continued refinement of precision miniature aerospace bearings, guidance and navigation systems of aircraft become more exact. Ring laser gyroscope, MEMS, fiber optic gyroscope, and other developments have made for more and more complex and tightly integrated cockpit systems.
