A Digital Revolution in Standby Instrumentation
The Trilogy™ Electronic Standby Instrument (ESI) is a panel-
mounted solid-state instrument that provides dependable backup
for attitude, altitude and airspeed information for Part 23 Fixed
Wing Aircraft and Part 27/29 Rotorcraft. The Trilogy ESI replaces
traditional electro-mechanical standby instruments and combines
the information into a compact and easy to read 4" x 3" display. Its
space-saving footprint, easy installation and complete digital design
make it the ideal standby for both new aircraft as well as those
outfitted with aging or traditional analog gauges. Heading is also
available, when coupled with the optional magnetometer, which
enables the system to display magnetic heading in a dedicated
window.
