A Passion for Navigation
The EHSI-4000 is defining a new standard for Electronic Horizontal Situation Indicators by utilizing a fully digital design and flat panel technology. Designed to replace older electro-mechanical horizontal situation indicators, the EHSI-4000 provides distance, bearing and course information in a 3-ATI size display, yielding a lightweight and compact layout. It combines the advantages of digital precision and solid-state reliability into a unit that is intuitive to operate in any environment.
With the incorporation of a powerful graphics processor and anti-aliased graphics, the EHSI-4000 provides superior capabilities offering an easy-to-read display as well as high reliability. The unit incorporates an Active Matrix Liquid Crystal Display (AMLCD) that is visible in direct sunlight as well as a dark cockpit. A built-in photocell on the front bezel, when used in conjunction with the setting of the aircraft bus, automatically adapts to ambient lighting conditions.

The EHSI-4000, when combined with the ESIS GH-3000, provides flight crews with comprehensive backup Air Data, Attitude and Navigation information. The “wraparound” capabilities of this coupled arrangement allow information sharing to insure consistent, reliable and redundant flight information. Sufficient redundancy is designed into this combination so that the loss of either unit will still provide important navigation information.
