AT-24 ​Instrument Landing System Trainer

Model AT-24 Instrument Landing System (ILS) 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 ILS receiver units (Marker, Localizer, and Glide-Slope), NAV/VOR/GS indicator, marker indicator, marker antenna, NAV and Glide-Slope antenna. Aircraft quality electrical shielded wiring, cables, connectors, and harness assemblies are used to interconnect all units. All units are easily removable. The workstation includes two test panel consoles for bench testing of ILS receiver equipment.

The trainer is supplied with a hand-held ramp tester that simulates several signals representing Localizer, Glideslope, and VOR deviations. Also, the tester simulates outer, middle, and inner markers.

Using Model AT-24, Avionics Instructors can effectively teach students on installing, removing, and testing ILS units. Students also develop proper understanding of the system and learn how to troubleshoot the ILS faults.
