Sensor States.
Displayed on sensor specific video only, and the messages will remain displayed until the sensor is
operational. Messages will be displayed during:
•
sensors temperature conditioning and calibration
•
during IR sensor cooling, COOLING will flash in the IR video until the sensor has finished cooling
•
during 1-Point or 2-Point IR calibrations, CALIBRATING will flash in the IR video
Note: Calibrating and Cooling messages will not be seen if the entire IR overlay is turned off.
2.2.3 Target and Aircraft Status Graphics
This overlay grouping provides aircraft and target status information that is located at the bottom portion of the video
display. Aircraft status is presented to the bottom-left side:
•
Aircraft position, altitude and heading. This information together with velocities and attitude data are obtained
from external navigational or GPS systems.
Target status is presented on the bottom-right side:
•
Target coordinates are calculated using aircraft position, altitude, velocities, turret’s attitude, and estimated or
measured target slant range values.
•
The target is always assumed to be centered in the video.
Terrain elevation is presented at bottom-center:
Note: Display units for coordinates can be configured from the Mission menu.
Figure 2-9 Target and Aircraft Status
Aircraft Coordinates.
Reports the aircraft’s geographic location data (lat/long). Display units can be configured by
the operator.
Aircraft Heading.
Reports the aircraft’s heading relative to True North.
Aircraft Altitude.
Reports the aircraft’s altitude above sea-level. Display units can be configured by the operator.
Terrain Elevation.
Reports the terrain ground elevation as the distance above or below sea level. This value can
be:
•
updated in real time as digital terrain elevation data (DTED) supplied by a Digital Map interface.
•
measured by a laser range finder.
•
entered manually as a fixed value in the user menus by the operator.
