L-3 Avionics Systems has received Approved Model List Supplemental Type Certification (AML STC) from the FAA for the Trilogy ESI-2000 Electronic Standby Instrument with battery backup. The ESI-2000 is a digital standby designed to replace the three analog backups commonly found in modern general aviation aircraft. Using lithium-ion technology, the Trilogy ESI-2000 combines the precision of solid-state avionics with a minimum of one hour and up to four hours of backup power if primary power is lost, according to company officials.
“Trilogy is more than a secondary source of flight data,” said Larry Riddle, vice president of business development for L-3 Avionics Systems. “With a mirror image of the primary flight display in the cockpit, pilots can make a smooth transition to this backup in an emergency or quickly spot a mismatch between systems. The ESI-2000 brings all-glass capability, improved safety and added system redundancy to a wide variety of aircraft.”
The Trilogy ESI-2000 is an advanced solid-state standby instrument that makes the all-glass cockpit possible. By displaying attitude, altitude, airspeed and optional heading data in a layout that matches most primary flight displays, the Trilogy ESI helps pilots quickly transition their visual scan to a secondary display without having to adjust to the different look of analog equipment. Single-screen backup flight information also saves weight and panel space by replacing up to three standby instruments.
In addition, the ESI-2000 includes 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 ESI is designed to supply usable flight data for three to four hours on battery power, depending on temperature exposure. Following emergency use, the battery is recharged by the aircraft’s electrical system with no need for removal or inspection. The battery’s maximum capacity is monitored by the ESI computer, which will notify the pilot when replacement is necessary.
L-3 Avionics Systems also offers the Trilogy ESI-1000 model, which features the same capabilities as the ESI-2000, but without the battery backup.
