IHADSS

The Elbit Systems of America® integrated helmet and display sight system (IHADSS) is a monocular system used in all current variants of Apache and Mangusta attack helicopters. A recent major upgrade makes it compatible with the Apache's Arrowhead PNVS thermal imager. The CRT-based, display unit attaches to the side of the helmet and feeds pilotage, navigation, and weapon-aiming symbology and imagery from the nose-mounted infrared camera to the crewmember's right eye via a half-mirror, optical combiner. The helmet, designed for use with night vision goggles features a 40 degree x 30 degree field of view, electro-optical head tracker, and may be upgraded by adding a plug-and-play night HUD module.
