In the United States, most avionics technicians receive an Associate's degree after graduating from a two-year technical school. The schools certify that a graduate knows electronics, math, and physics. The electronics instruction includes analog and digital circuits, power supplies, radio transmitters and receivers, antenna theory, and more. Specialized material on radar, distance measuring equipment, transponders, control panels, and instruments prepares a student for a career in aviation.
Once a student finds employment, on-the-job training begins with a general familiarization school on the aircraft types the student will encounter. This is an introduction to the specific manufacturer's nomenclature and manuals so that the new employee can find things aboard the aircraft. Large commercial airlines may have their own schools on soldering, test equipment, personal and chemical safety, ramp operations, and much more. In some cases, employees attend classes with the original equipment manufacturer for intensive instruction.
