Aircraft Electrical System Laboratory - June 2018

The aircraft electrical system trainer is an ideal resource to teach about an aircraft multiengine electrical system. By using this trainer, students not only learn the functionality of each component, but they also develop logical and systematic approach to perform troubleshooting tasks. The system is laid out to depict a typical aircraft electrical system, and contains standard aircraft components and wiring. This laboratory is a complete functional simulation of a dual-engine 28V DC electrical system of a typical turbine aircraft.

This trainer set has been using to teach the students both parallel generator bus configuration (like DC-10, Boeing 727, etc.) and split bus configuration (like Boeing 757, Boeing 767, MD-80, Airbus A320, etc.).
