CHAPTER 4
DIGITAL IMAGE GENERATION SYSTEM
Section I. GENERAL DESCRIPTION
4-1. GENERAL.
4-2. The simulator uses a digital image generation (DIG) system to provide the necessary visual displays. A computer-
generated data base provides tactical and instrument gaming areas of approximately 8,000 square kilometers each. The
gaming area represents a generic terrain designed specifically to meet diverse training requirements related to cargo
helicopter operations.
4-3. OUT-THE-WINDOW DISPLAYS .
4-4. The simulator visual system provides full visual displays in four OTW displays (two forward and two side). The
display images are supplied by the DIG, which simulates day, dusk/dawn and night operations.
4-5. CHIN WINDOW DISPLAYS .
4-6. Chin windows are located on the left side of the copilot and on the right side of the pilot, both at cockpit floor level.
Chin window displays are compatible with the OTW scene.
4-7. Each chin window display monitor assembly uses a self-contained color monitor and reflective optical assembly that
together provide a collimated display image. The self-contained color monitor accepts the video signal from the digital
image generator, processes these signals, and displays the resultant color images on the CRT. The various
configurations of chin window and forward and side window displays are determined by the instructor and are shown
below:
