(Click image for a larger view) | The TRA-3000 and TRA-3500 Radar Altimeters are used with the TRI-40 indicator.
This panel mounted indicator provides essential information when there are no visual clues to the landscape surrounding the airport or the pilot's flight path. The indicator displays the AGL altitude and the pilot's preselected decision height (DH) in a bright, LED readout, and provides an audible warning when descending below the DH. A test button sends a 40-foot altitude code to the indicator to test the display and warning alerts at any time. The TRI-40 Indicator also includes a visual and audible gear-up warning when the aircraft is below 100 feet. A trip-point output allows the pilot to activate additional alerts every 100 feet up to 800 feet. A TRI-40 Indicator mounted in a round faceplate adapter is available as an option to simplify certain installations. |
