L-3’s Trilogy™ ESI-1000 Receives European Technical Standard Order Authorization

Level A Standby Now Available for European Customers

GRAND RAPIDS, Mich., August 19, 2010 – L-3 Avionics Systems announced today that it has received European Technical Standard Order (ETSO) Authorization from the European Aviation Safety Agency (EASA) for the Trilogy™ ESI-1000 Electronic Standby Instrument, an advanced solid-state standby that makes the all-glass cockpit possible in today’s modern aircraft. Software and Complex Electronic Hardware for the most current version of the ESI-1000 were developed to Design Assurance Level A, the highest safety standard acknowledged by EASA. The ESI-1000 is available now.

"By providing easy-to-scan flight data in an arrangement similar to the primary flight display, the Trilogy ESI helps pilots maintain situational awareness and control the aircraft after primary avionics fail," said Larry Riddle, vice president of business development for L-3 Avionics Systems. "In Europe’s notoriously busy skies, this enhances safety and ultimately leads to a routine landing. L-3 is excited to offer the security and visual seamlessness of an all-glass display to our European customers."

The ESI-1000 merges attitude, altitude, airspeed and optional heading data onto a sharp 3.7-inch screen. By combining three instruments into one, the Trilogy ESI also saves panel space, replacing the multiple analog backups that normally accompany glass cockpit avionics.

With an integrated air data computer, solid-state attitude sensor and optional external magnetometer, the ESI-1000 provides precise flight data independently, giving pilots an extra reference point to verify the accuracy of other systems. The Trilogy ESI’s four-button pilot interface, automatic brightness control and dimensions, which match the standard 3-ATI mounting cutout, make the unit easy to operate and install. Once activated, the ESI is typically aligned and ready for flight in less than two minutes.

Recent enhancements include an on-screen slip indicator, which helps pilots stay coordinated without referring to other instruments in a dark cockpit, and a pop-up metric window, which facilitates quick altitude conversions during international flights.

The Trilogy ESI was developed with L-3 Avionics Systems’ advanced solid-state expertise, which has made the company a leader in electronic standby instrument systems for high-end aircraft. The Trilogy instruments now bring this expertise to the general aviation market.

L-3 Avionics Systems has been helping pilots fly for more than 45 years. The company provides a wide array of avionics technologies designed to improve situational awareness and enhance safety, such as the GH-3000 electronic and J.E.T.® standby instruments, the SkyWatch® Collision Avoidance System, the Stormscope® Weather Mapping System and the Trilogy™ Electronic Standby Instrument, among others.
