L-3 Aviation Products (L-3 AP) announced today that Viking Air Limited has selected the GH-3900 Electronic Standby Instrument System (ESIS) for installation on new production Viking Twin Otter Series 400 aircraft.

“For decades, the de Havilland legacy Twin Otter aircraft have been utilized for the hardest jobs in the toughest places,” said Ralph DeMarco, vice president of sales and marketing for L-3 Aviation Products. “Equipped with the GH-3900 ESIS, the Viking Series 400 Twin Otter will continue to live up to its predecessor's reputation for versatility and dependability in extreme operating environments.”

Designed to Level A software and hardware standards, the GH-3900 ESIS is capable of satisfying airworthiness requirements for almost any transport category fixed- or rotary-wing aircraft. The GH-3900 is a more precise and information-rich standby than traditional analog instruments, rendering all the important cues on a sunlight-readable, three-inch display. With a customizable layout, L-3's GH-Series standby instruments can be modified to fit a wide range of primary systems, giving pilots a familiar reference for flying the aircraft.
