The GH-3900 Electronic Standby Instrument System (ESIS) represents the next-generation of standby instrument technologies and capabilities for mid- to large cabin business turboprops and jets and helicopters, as well as air transport category aircraft. Along with being a full-function standby ADI, the GH-3900 offers pilots an unmatched array of configuration options, including customizable colors and visual flight cues, as well as displayed information tailored to Part 23 (Class III & IV), 25, 27 and 29 aircraft and helicopters.
To ensure the GH-3900 would fit in the majority of aircraft and helicopters – even those with limited space behind the panel – the unit is a full 1.5 inches shorter than prior GH-Series models. In addition the system’s Configuration Module has been designed into the wiring harness, which itself features a more compact connector.
The GH-3900 ESIS can be programmed to provide numerous display options. Once defined, colors and visual flight cues are stored in the aircraft’s wiring, eliminating the need for a separate configuration module. And the instrument’s Menu button makes changing, adding or deleting display features push-button easy. Interfaces with other avionics are simply managed through the GH-3900’s Configuration Module Tool software.
