Avionics Pro contains virtually every tool needed to quickly solve homework problems and preview electronic lab experiments for the student who is completing a course of study to become an Aircraft Electronics Technician (AET). Specifically, it emphasizes Introductory Aircraft Avionics, featuring real world circuits that have been tested using an industry standard circuit simulator (Multisim) as well as in an actual electronics lab environment. Beyond the AET course, Avionics Pro is a handy refresher for graduate technicians in the industry as well as students looking to expand their understanding through higher education engineering courses. Avionics Pro features graphics support for all standard Apple phones and iPads.
