GH-4001 ESIS

Sunlight readable AMLCD with LED backlight…and more

The unit, which features a sunlight-readable AMLCD with LED backlight, aligns in less than a minute after startup. The GH-4001 has the capability to display Rotor Speed and Vertical Speed tapes. The preferred presentation of flight data as well as software updates can be accomplished in the field, eliminating the need to remove the unit for display updates. The GH-4001 also features a system status menu page, simplifying the maintenance of the unit.

Configurable for single and tandem pilot aircraft

The 3-ATI GH-4001 is configurable for single and tandem pilot aircraft, with a GH-4001 repeater display available for multiple cockpits. The ruggedized GH-4001 is designed to integrate with existing magnetometers and contains high rate sensors built to Mil-qualification standards, enabling it to be installed on any platform. The GH-4001 is a direct replacement for the GH-3001 model and uses the same wiring harness and connector.
