By Staff Writer | September 1, 2009


Grand Rapids, Mich.-based L-3 Avionics Systems has obtained technical standard order (TSO) authorization and an approved model list (AML) supplemental type certificate (STC) for its Trilogy ESI-100 electronic standby instrument. Trilogy was developed as a backup for glass cockpit avionics and designed specifically for Part 23 aircraft.

The AML STC "allows the Trilogy ESI to be installed in a variety of cockpits," explains Larry Riddle, vice president of business development for L-3 Avionics. The unit combines altitude, attitude, airspeed and optional heading data on a 3.7-inch active matrix LCD screen.
