ATT 203 - Avionics Test Equipment

4 Credits, 6 Contact Hours
2 lecture periods 4 lab periods

Overview of the evolution of modern avionics systems, test equipment, and operation of and training on test equipment. Includes functional testing of pitot static, transponder and altitude reporting units, Very High Frequency Omni-directional Range (VOR), Global Positioning Systems (GPS), and compass navigation devices installed in aircraft or functioning mockups. Also includes special tooling and test apparatuses, the handling of aircraft, and safety for personnel and equipment undergoing testing.

Prerequisite(s): ATT 104  
Information: Additional self-paced independent course study materials are required for non-certified Airframe and Powerplant students.

Course Learning Outcomes
1.   Review a logbook entry with emphasis on finding anomalies.

2.   Demonstrate a conformity inspection on an avionics installation.

3.   Follow written procedural steps to accomplish a compliance test.

4.   Inspect and correct standard stand-by compass deviations.

5.   Read and follow documentation to inspect and troubleshoot static systems.

6.   Acquire technical data for transponder, encoder, and Reduced Vertical Separation Minimum (RVSM) inspections.

7.   Review provided documentation for an inspection and troubleshooting of a VOR and Instrument landing System (ILS).

8.   Verify modifications to an existing Global Positioning System (GPS) installation are done in accordance with approved technical data.

9.   Identify antenna locations and perform approved testing procedures on an antenna or static wick.

Note:  This is an accelerated overview course. It is the responsibility of the student to use 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 in good standing will be required to review and test on supplemental material available (on CD-ROM) for check out from the Aviation Technology Center’s tool crib. Proof of current enrollment is required.

Effective Term:
Fall 2016
