Electronic Standby Instrument Systems
A panel full of capabilities housed in a compact, multi-capability standby display unit
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.
Small size, big flexibility
The GH-3900 offers pilots and installers a variety of configuration options for the displays. Designed with Level A hardware and software standards, the unit allows the installer to define and configure I/O interfaces, Static Source Error Correction (SSEC) and Velocity Maximum Operations (VMO) values, as well as the pilot’s preferred presentation of altitude, attitude, airspeed, heading and navigation data.
Unmatched display configurability
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.
Designed for installation flexibility
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.
