L-3 Avionics Systems announced today that it has received Technical Standard Order (TSO) Authorization and an Approved Model List Supplemental Type Certificate (AML STC) from the FAA for its new TrilogyTM ESI-1000 Electronic Standby Instrument. Designed as a backup for glass cockpit avionics, Trilogy is the first solid-state integrated standby system created specifically for Part 23 aircraft. The instrument will be on display at EAA AirVenture, Hangar C, Booth 3100, July 27 through August 2.

"The AML STC allows the Trilogy ESI to be installed in a variety of cockpits. Now, most Part 23 aircraft are candidates for Trilogy, which can replace the old standby technology with glass," said Larry Riddle, vice president of business development for L-3 Avionics. "We're looking forward to seeing numerous all- glass piston and turbo-prop aircraft in the skies—something Trilogy makes possible for the first time."

Trilogy combines attitude, altitude, airspeed and optional heading data on a clear, 3.7-inch diagonal Active Matrix LCD display. The instrument fits easily into a standard 3–ATI mounting cutout. With an integrated air data computer, solid-state attitude sensor and optional external magnetometer, Trilogy presents accurate flight information independently of other systems. In the event of a primary glass failure, Trilogy facilitates a smooth transition from primary to standby instrument because it provides a common format to today's primary flight display. It enhances safety by reducing workload and making the transition easier for the pilot.

An ambient light sensor is integrated for automatic brightness control on both the screen and keyboard. Trilogy units will be calibrated to 400 knots and 55,000 feet, with the ability to store aircraft configuration and options at time of installation. The model will be available through OEMs as well as for retrofit to modernize both glass and traditional cockpit configurations.

Trilogy was developed from L-3 Avionics Systems' advanced knowledge base and performance in strapdown attitude determination, which has made the company a leader in electronic standby instrument systems for high-end aircraft. Now, Trilogy makes this technology a smart and affordable option for all general aviation pilots.
