I-Nights HMD:

I-Nights is an  Integrated Night Vision HMD providing sensor imagery and integrated night vision at night with flight and targeting symbology available both day and night. The binocular prismatic optical system provides a 40degree Field of View from a CRT and/or a NVG. The information (symbology and raster video) is projected onto a clear combiners placed in front of each of the pilot’s eyes. The system incorporates a one piece module for both day and night missions which clips on to an inner helmet shell such that the inner is form fitted to the pilot but the complex outer is interchangeable. The HMD operates with a pulsed DC Magnetic Tracker system.

The HMD was first flight tested used for PAH-1/AVT trials in Germany with the German Army Air Corps and also on the Integrated Night Vision Helmet (INVH) programme with the US Navy when comprehensive flight qualification testing was carried out in 1989 and 1990.The HMD was cleared for rotary wing and jet flight test (450 knot) and used with head-steered FLIRs. Other testing was carried out on the F-16 (AFTI), German Airforce Tornado, C-130 and a number of helicopters such as the BO-105, Lynx, Gazelle, BK-117. A proposal was submitted to McDonnel Douglas in 1990 by the Company for the F/A-18 but was not successful.

An advanced version of the I-Night HMD was produced for USAF flight trials on the AFTI F-16.  This system flew out of Edwards AFB and followed on from Falcon Eye using a dual FLIR sensor to provide both pilotage and targeting FLIR display to the pilot on his HMD. This was the first use of picture in picture to display pilotage FLIR over the full HMD field of view, with an inset pop up picture of the targeting FLIR imagery.
