The US Armys AH-64 Apache attack helicopter has been fielded since the early 1980s Figure 1. There are currently two models A D of the Apache. The latter D-model differs primarily from the A-model in cockpit design and the addition of a mast-mounted millimeter radar system. The AH-64 is a tandem-seated aircraft with the pilot occupying the rear seat and the copilotgunner occupying the front seat. Both pilots fly and perform fire-control procedures using a monocular helmet-mounted display HMD known as the litegrated Helmet and Display Sighting System IHADSS Figure 2. The IHADSS provides pilotage and fire-control imagery from separate forward-looking infrared FLIR sensors mounted on the nose of the aircraft. Flight symbology is integrated embedded into the HMD imagery. The FLIR sensor that provides the pilotage imagery is known as the Pilots Night Vision System PNVS the FLIR sensor that provides the fire-control imagery is known as the Target Acquisition and Designation System TAD S.
