4.5 VIDEO RECORDER SUBSYSTEM (VRS).
The VRS consists of an airborne video recorder, located in
the left side of the aft avionics bay (fig 2-2), and the video
recorder control panel, placarded RECORDER (fig 4-3),
located in the CPG left console (fig 2-12). The VRS has
the capability of recording up to 72 minutes of either pilot
or CPG selected video. Capability exists for playback on-
board the helicopter for real time damage assessment
and reconnaissance. The VRS receives 115 vac from the
No. 2 essential ac bus through the RCDR circuit breaker
on the CPG No.1 circuit breaker panel. The VRS is not
monitored by FD/LS. The video tape recorded onboard
the helicopter requires a special video playback unit to
view the imagery off the helicopter. The video recorder
control panel control/indicator functions are discribed in
table 4-3.
