ATT 201 - Operating Systems II, GPS Navigation and Auto Pilot 3 Credits, 3 Contact Hours
3 lecture periods 0 lab periods
Principles of Global Positioning Systems (GPS) and autopilot systems operation and use by flight crews. Includes installation planning for electrical system requirements, typical mounting, wiring methods, connectors, and antenna installation. Also includes pre- and post-installation verification of system integration, functional testing, and troubleshooting on GPS and autopilot systems.
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. Perform a specific flight characteristic unique to a component of an aircraft.
2. Illustrate individual flight control surfaces and their relationship to the autopilot system.
3. Plan and execute a flight plan using Visual Flight Rules (VFR) planning techniques.
4. Develop and perform a flight plan using Instrument Flight Rules (IFR) planning techniques.
5. Display, through the use of a flight simulator, a go-around maneuver.
6. Describe the National Airspace System (NAS) and explain how it applies to avionics.
7. Describe the integration of an advanced navigation system.
8. Remove an older system and install a modern system.
9. Troubleshoot and perform functional test on existing and newly installed equipment.
10. Modify and design existing schematics to replicate new installations.

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
