L-3’s Avionics Systems (Static F 186) continues its success in the field of providing electronic standby instrument systems (ESIS) with further selections of the company’s products for high-profile aircraft programs. Cessna Aircraft has selected the L-3 GH-3900 ESIS for the latest Citation Ten model, the system replacing conventional electromechanical standby instruments with a combined flight and navigation data display on a three-inch screen.
Emphasizing L-3’s capability in this arena is the selection of the company’s ESIS systems for the international variants of the Boeing F-15 Eagle and F/A-18 Super Hornet. L-3 will provide two GH-4200 reference standby display (RSD) instruments for the F-15, and a single RSD and GH-4000 reference standby display repeater (RSDR) for the F/A-18.
Both systems provide attitude, altitude and airspeed data in a layout that matches that of the primary systems. Heading, slip/skid, vertical speed and navigation data can be added as options. The RSD/RSDR features an integrated air data sensor card and has direct connections to the pitot/static system, removing the need for a separate air data computer.
