ATT 103 - Basics of Avionics Installation 3 Credits, 4 Contact Hours
2 lecture periods 2 lab periods
Concepts, techniques, and skills used to install electronic and avionics equipment. Includes avionics support structure installation and fabrication; instrument mounting; terminal installation; cutting, sizing, marking, bundling, and anchoring techniques and practices; handling precautions for sensitive devices; and selecting proper equipment and tools. Also includes a review of electrical equipment bays, wiring diagrams, installation drawings, circuit protection devices, lighting processes, and regulatory requirements.
Information: Additional self-paced independent course study materials are required for non-certified Airframe and Powerplant students.

Note: This is an accelerated overview course. It is the responsibility of the student to use the supplemental information on subjects that are not fully understood. At the instructor’s discretion, a student without a current “A” airframe certificate issued from the FAA will be required to review and test on supplemental material that will be available (on CD) to the student for check out from the Aviation Technology Center’s tool crib. Proof of current enrollment is required.
