2.18.7.2 HUD Camera. The HUD camera, positioned immediately in front of the HUD, records a
color image similar to what the pilot sees through the HUD, e.g., symbology superimposed on a picture
of the outside world. This combined image is made available to VTR 2 for recording.
2.18.7.2.1 HUD Event Marker. The HUD event marker is a small black marker generated by the
HUD camera and positioned in the upper left corner of the video signal sent to VTR 2. The event
marker is displayed when the weapon release pickle button is pressed or the trigger is squeezed to the
second detent and remains displayed until pickle button/trigger release. When reviewing CVRS video
post-flight, the event marker is a useful training aid, used to determine the timing and duration of
pickle button and trigger actuations (e.g., shot validation).
2.18.7.2.2 HUD Camera BIT Button. The BIT button, located on the front face of the HUD
assembly, is used to initiate a BIT of the HUD camera. The GO and NO GO BIT status balls, normally
black, are used to determine the BIT status of the HUD camera. When the BIT button is pressed, BIT
status is indicated by a green GO ball or an orange NO GO ball.
2.18.7.3 Over-the-Shoulder Cameras. Two over-the-shoulder cameras, one mounted on each side of
the canopy frame approximately 30 inches from the instrument panel, are oriented to record a picture
of the L and RDDIs. The image from each camera is made available to VTR 1 for recording.
2.18.7.3.1 Over-the-Shoulder Camera BIT Buttons. Each camera contains a BIT button located on
its front face. Press and hold of the BIT button initiates a BIT of that camera. BIT status is indicated
by a green LED (go) or a red LED (fail).
2.18.7.4 CVRS Control Switches. The switches used to operate CVRS are located on the VIDEO
RECORD panel on the lower left instrument panel in each cockpit.
2.18.7.4.1 CVRS Mode Switch. The CVRS mode switch is used to select manual or automatic video

MAN CVRS records continuously (according to the inputs selected by the two VTR
selector switches).
OFF CVRS recording off.
AUTO CVRS records automatically only when in the A/A or A/G master modes (according
to the inputs selected by the two VTR selector switches).
2.18.7.4.2 CVRS RDCR ON Light. The green RDCR ON light, located on the left warning/caution/
advisory lights panel on the upper left instrument panel, comes on when CVRS is recording.
2.18.7.4.3 VTR 1 Selector Switch. The VTR 1 selector switch is used to select the video input source
for recording on VTR 1. For F-18E and F-18F front cockpit:

For the F-18F rear cockpit:
MPCD Selects direct video input to the MPCD.
UFCD Selects direct video input to the UFCD.
2.18.7.4.5 CVRS Mode Switch (F/A-18F). The rear cockpit CVRS mode switch is used to select front
or rear cockpit control of VTR 1. This switch is spring-loaded to the FWD position and is electrically
held in the AFT/MAN position.
FWD Selects front cockpit control of VTR 1.
AFT/MAN Selects rear cockpit control of VTR 1.
2.18.7.4.6 VTR 1 Selector Switch (F/A-18F). The rear cockpit VTR 1 selector switch is used to select
the video input source for recording on VTR 1 when the rear cockpit CVRS mode switch is in the
AFT/MAN position.
UFCD Selects direct video input to the AUFCD.
MPCD Selects direct video input to the AMPCD.
2.18.7.5 VTR 2 Override Function. CVRS incorporates a VTR 2 override function designed to make
sure that HUD camera video is recorded when an A/G weapon is released, the gun is fired, or an A/A
missile is launched. In A/A or A/G master modes, when the pickle button is pressed or the trigger is
squeezed to the second detent, VTR 2 automatically switches from the MPCD or UFCD to the HUD
