Notes:

This is an EO-200 Overhead Unit from the 2020 Civil HUD system.

In 1994 Honeywell teamed with GEC Avionics on HUD and the system was marketed as the HUD 2020, because of the link to good vision; it comprised a compact CB-200 monochrome combiner and EO-200 electro-optical overhead unit, together with the HG-200 digital headup guidance computer which was made by Honeywell. The HUD 2020 weighs only 23 kg with much of the saving coming from the extremely lightweight Combiner which is only 4mm thick. The Combiner is curved and extremely thin with a frequency selective coating made up of several hundred layers of variable refractive index material called a ‘rugate’ coating.

The 2020 system was certified to Category II and is offered as a standard option on the GIV, GIV-SP and GV

The original Gulfstream IV HUD was stroke only with "growth to raster" built in, but never taken to full production.

Honeywell developed an Infra-Red system with Kollsman which gave night vision through the HUD. The later HUD was a full raster/cursive capable unit and this system was an option on the Gulfstream. It was called EVS Enhanced Visual System.
