The L-3 Avionics System electronic standby instrument system (EFIS) has been selected by Cessna as standard equipment for the Citation CJ1 and CJ2. The GH-3000 system is already on the CJ3, Bravo, Encore, XLS and Sovereign aircraft. The avionics display provides pilots with a complete situational picture as a standby to the Rockwell Collins Pro Line 21 EFIS displays in these cockpits. The 3-inch ATI format flat-panel display replaces conventional electromechanical standby attitude, airspeed and altitude instruments.
