Field of Regard Box. The large rectangle centered

along the bottom section of the IHADSS display is the

field-of-regard box. It represents the 220° x 90° field of

view of the TADS camera. When you pan the TADS

camera left or right, the small rectangle inside this box (the field of view marker)

moves accordingly. (See Alternate Sensor Bearing (11) for camera slew commands.)

Field of View Marker. This small rectangle inside the field of

regard box (15) indicates where your TADS camera is pointed in

relation to the current flight path of the helicopter. The rectangle

describes the TADS camera’s current field of view. (This box simu-

lates what the CP/G can see in reality without moving the TADS sensor package.)

FCR Centerline. This centerline appears in the field of regard

box (15) and shows the current bearing of the target locked by the

Fire-Control Radar. A small horizontal line across this centerline

shows the elevation of the radar in relation to the field of regard.

Velocity Vector. This line between the center of the sight

reticule and a small dot is an overhead, graphical representation of

the helicopter’s lateral velocity. It takes both speed and severity of

motion (such as turning sharply) into account. The faster the heli-

copter is traveling, the longer the line. It points in the direction the helicopter is

traveling.

Acceleration Cue. This mobile circle is similar to the velocity

vector, only it provides a graphical position that takes into account

the helicopter’s current acceleration. The higher the rate of acceler-

ation, the further the circle moves away from the center of the

viewscreen.

Engine Torque Readout. This digital indicator shows how

much torque is being output by the engines, and displays the

highest torque of the two engines. A torque value of 98% or greater

causes this box to gain a solid border, alerting the pilot that the

torque limit has been exceeded.

You can over torque for a while but it adds excessive wear and tear to the heli-

copter.

If torque is too high, reduce collective.
