5-6. VISUAL SYSTEM. Two DIG systems are used in the CMS, differing only in the
number of channels offered and in the hardware required related to that differ-
ence. The same software is used for both DIG's.
a. There are timing constraints or desired system performance to provide high-
density scenes with DTV and FLIR images at a 60-Hz rate.
b. The DIG's consist of a three-channel DIG system and a one-channel DIG sys-
tem. The three-channel system provides either a three-channel out-the-window (OTW)
display or pilot night vision sensor (PNVS) video. The one-channel system provides
simulation of the three target acquisition and designation system (TADS) sensors:
forward-looking infrared (FLIR), day TV (DTV), and direct-view optics (DVO). Since
there are only two DIG systems, there are limitations on the number of visual dis-
plays that can be viewed simultaneously. (Table 5-1 lists the displays available
in each cockpit during integrated or independent CMS operations.)
5-7. AUDIO SYSTEM. Once programmed, accompanying audio cannot be turned off while
a demonstration continues. Audio is not available during slow-time playback. A l l
aural cues are limited in loudness to within established safe levels of hearing.
Sounds associated with rain and hail are not provided.
5-8. IOS CRT-CONTROLLABLE PARAMETERS. The CRT display pages provide instructor
control for aircraft environment, flight, and miscellaneous related parameters.
Selectable values for edit are limited within the range normally found in a
realistic world or within the limitations of the actual helicopter.
