Avionics Installation for Experimental Aircraft

This course is designed for the homebuilder or avionics technician who is looking for guidance in completing an avionics installation on an experimental aircraft. While the Garmin G3X Touch system is used as an example in the course, the wiring principles and general guidance can be applied to any experimental avionics system. From the do-it-yourselfer to the avionics shop looking to carve a niche, this class has something for everyone.

This class will begin with an overview of wiring basics, but it will quickly advance through the common practices involved in wiring. Students will spend a significant portion of this course learning, hands-on, how to wire a G3X Touch system. Attendees also will learn how to plan, install, interface and configure the G3X Touch system.
