Aviation's Panel Mount Avionics Installation Leader

The RAD-40 (TSO-C87) is a panel-mount digital display, compatible with the FreeFlight Systems RA-4000 and RA-4500 Radar Altimeters. This display provides the pilot with a precise readout of the aircraft’s height above-ground-level on a bright LED readout. The RAD-40 includes a pilot-selectable Decision Height (DH) and five additional trip points (100-1000 ft.), all with discrete outputs designed to control an audible tone or interface to third party equipment. Activating the trip points provides alerts to the flight management system (FMS) or navigation management system if the aircraft descends through these altitudes -- an additional safety feature for the pilot.

In addition to the standard version, a Night Vision Goggle (NVG) compatible display is available. For certain installations, a display mounted in a round faceplate adapter is also offered as an option.
