CHAPTER 6

VISUAL SYSTEM

6-1. GENERAL. The AH-64 CMS utilizes two digital image generation (DIG) systems

to provide the necessary visual displays. A computer-generated data base provides

a tactical gaming area and an airfield area of approximately 1,200 square kilo-

meters (32 x 40 km). The gaming area is a generic terrain representation that was

specifically designed to meet the diverse training requirements related to attack

helicopter operations.

NOTE

Since these are only two DIG systems provided with the CMS,

there are limitations on the number of visual displays that can

be viewed simultaneously. (Chapter 5 lists the displays

available in each cockpit during integrated or independent CMS

operations.)

a. Out-the-Window Displays. Each cockpit has three out-the-window displays

(left, front, and right). In the independent mode, each cockpit requires the use

of its DIG system to provide OTW scenes. In the integrated mode, one DIG provides

OTW scenes to both cockpits but from the pilot's perspective.

b. Sensor System Displays. The visual generation system has the capability of

providing imagery to every sensor display in the CMS. These include the pilot

IHADSS with PNVS and symbology, the OTW scene, and the VDU. The pilot can also

monitor the CPG TV or TADS FLIR on the VDU during integrated flight training. The

CPG has displays for IHADSS and ORT heads-down display (HDD), plus heads-out

displays (HOD) for TV and FLIR.
