The TADS Electronic Display and Control (TEDAC) is the modernized replacement for the Optical Relay Tube (ORT) located in the co-pilot/gunner (CPG) crewstation of the AH-64 Apache Helicopter. The TEDAC presents the CPG with high resolution sensor video from the Modernized Target Acquisition and Designation Sight (M-TADS) (known as "Arrowhead").
TEDAC replaces the ORT's small CRT display and direct view optics with a large 5" x 5" flat-panel cockpit display that utilizes active matrix liquid crystal display (AMLCD) technology. This higher resolution display improves the CPG's ability to engage targets while providing greater situational awareness and more survivable space in the cockpit.
In comparison to the ORT, TEDAC provides substantially higher reliability. Moreover, its modular design and improved fault detection allow for simpler two-level support. These improvements reduce system maintenance and operational downtime by 50%.
