90-00 Description (continued)
A transmit switch for the left front seat is provided on the floor near the observer’s right
heel. An intercom switch for the left front seat is provided either near the observer’s right
heel or at the outboard base of the seat box. An optional transmit switch for the left rear
seat is also available. The optional switch is handheld on a cord which plugs into a jack
beneath the left rear seat ICS button. Transmit functionality is tied to the selection on the
observer’s audio panel.
The center rear seat has been replaced with an arm rest and storage console.
Baggage is not permitted in the right rear under-seat compartment due to electronic
equipment and wiring in that compartment.
An interior wall has been added to the main baggage compartment to create an electronic
equipment compartment at the aft end.
Extended forward landing gear struts provide additional ground clearance for the camera
and searchlight. The ground clearance at the tail is reduced by approximately 8 inches with
the helicopter parked.
The infrared camera system consists of a gyro-stabilized, gimbal-mounted infrared/video
camera in the chin and a power junction box in the main baggage compartment behind the
interior wall. The camera is operated by the observer in the left front seat via a handheld
controller. A tray and strap forward of the circuit breaker panel are provided for controller
stowage when not in use.
A flat screen LCD monitor is located in front of the left front seat to display camera images.
For the earlier cockpit configuration, the monitor is equipped with a visor to minimize glare.
The monitor mount is hinged to retract forward and down, out of the observer’s way, when
not in use.
For the later cockpit configuration, the monitor has no visor but is easily dimmed using a
knob on its front face. The monitor mount is hinged on its inboard edge, and the monitor
folds back against the left side of the instrument console, out of the observer’s way, when
not in use.
The optional digital video recorder (DVR) is mounted just aft of the space between the front
backrests and controlled by a switch at the observer’s station. The DVR can record images
from the camera and play them back on the LCD monitor.
