L-3 Trilogy gets own power source

trilogyL-3’s Trilogy—a glass-panel standby instrument that provides attitude, altitude, and airspeed information—will soon come with its own backup battery.

L-3 has applied for FAA approval to add a lithium-ion battery to the Trilogy that could allow it to function for four hours on its own power. The Trilogy has a bright, 3.7-inch display and is approved for use in both airplanes and helicopters. Owners can add optional heading and turn coordinators to the standalone units.

“With its own internal power source, the Trilogy ESI-2000 design is even more versatile,” said Larry Riddle, L-3 vice president for business development. “When primary systems falter, the ESI-2000 gives fixed- and rotary-wing operators a reliable source for relevant flight information, even after a complete power loss. The Level A design takes safety measures to the highest level and provides added assurance in the cockpit.”
