L-3 Avionics Systems, based in Grand Rapids, Mich., said its GH-3900 Electronic Standby Instrument System (ESIS) has been selected by Rockwell Collins for its Pro Line Fusion integrated avionics system. The contract is for 10 years with production units slated for 2012. The GH-3900 is the next generation in L-3 Avionics' GH series of electronic standby systems. Designed to replace conventional electro-mechanical standby attitude, airspeed and altitude instruments, the solid-state GH-3900 ESIS is capable of providing all three functions, plus heading, slip/skid, navigation data, and vertical speed in a single 3-inch flat-panel display, the company said. The GH-3900 features an integrated air data sensor card with pitot static connections directly to the unit, which eliminates the need for a remote mounted air data computer, according to L-3.
