Model AT-30 Aircraft Navigation Systems Trainer is designed to provide hands-on training on a real and operational equipment approved for aircraft installation. The equipment is mounted on a mobile workstation containing aircraft navigation radio, indicator, and the NAV antenna assemblies. All interconnections are of aircraft quality electrical shielded wiring, cables, connectors, and harnesses. The workstation includes a test panel console for bench testing of NAV electronics.

Using Model AT-30, Avionics Instructors can effectively teach students on installing, removing, and testing as done on flight lines. Students develop proper understanding and learn to troubleshoot the NAV Systems.

Installed Systems:

VOR, Localizer, Glide Slope,Marker Beacon,ADF,H.S.I system (directional gyro and magnetic flux detector)

Documentation:

• Technical Reference Manuals
