Product overview

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.

Key features

Small size, big flexibility

The GH-3900 ESIS offers pilots and installers a variety of configuration options to meet the needs and preferences of almost any cockpit environment. Designed with Level A hardware and software standards, the unit allows the installer to define and configure I/O interfaces, Static Source Error Correction and Velocity Maximum Operations 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. 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 ESIS fits in the majority of aircraft and helicopters, 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.
