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. SECTIONS: - IMPEDANCE -- Series LRC -- Parallel LRC - RESONANCE -- Series LRC -- Parallel LRC -- Missing Component Calculator - FILTERS (Includes circuits and frequency response graphic) -- Low Pass (RC & RL) -- High Pass (RC & RL) -- Band Pass (RC) -- Band Reject (RC) -- Band Pass (Series Resonant) -- Band Reject (Parallel Resonant) - TIME CONSTANTS -- RL/RC Charging/Discharging - TRANSISTOR BIAS -- 2N222 (Bipolar Junction Transistor) - OSCILLATORS -- Colpitts -- Hartley DISCLAIMER The user of Avionics Pro for any specific application without an independent verification of its accuracy does so at his/her own risk and assumes any and all liability resulting from such use.

The building code calculator (BCC) application is set up to be able to perform a range of calculations pertaining to occupant load, minimum number of required plumbing fixtures, etc. with easily usable menus and functions for specific space functionalities. Additionally, the BCC can function offline and generate a copy of calculation steps, both of which are invaluable to on-site work and report/permitting generation. This represents a marked improvement in methods currently employed by building industry professionals; also, the BCC has the potential as a successful educational tool. Both survey and biometric data from senior interior design student volunteers show that using the BCC reduces stress levels and helped to accomplish the building tasks performed. The BCC will save time and reduce errors generated from building code calculations done by building and space planning professionals as well as help students in educational settings to master design concepts.
