Figure 5-19.-Copilot/COTAC display format.
The basic copilot/COTAC display format is
shown in figure 5-19.
TACCO AND SENSO DISPLAYS
The TACCO display provides the video
presentations listed below:
Alerts and cues from the GPDC
Tableaus containing GPDC-stored data
TAC plot composed of symbols, vectors, and
conics
Analog acoustic data from the acoustic data
processor (ADP) in the form of frequency,
bearing, and range information from active
sonobuoys (pingers) and signal strength from
passive sonobuoys
FLIR
MAD
BT
Scan-converted radar
Raw radar
Test patterns
The TACCO and SENSO display formats are
identical, and are shown in figure 5-20.
SENSO ARU DISPLAY
The SENSO ARU displays analog acoustic data
from passive sonobuoys. This data includes
frequency, bearing, and signal strength.
TACTICAL DISPLAY SYSTEM INTERFACE
As was previously mentioned, the TDS is the
primary means used by the GPDC to present
information to the operators. As shown in figure
5-21, the GPDC sends commands to the DGU. The
DGU interprets them, determines the operating mode,
and generates the requested symbols or displays. The
DGU also regulates the data flow rates from the FLIR,
radar, and the ADP to allow direct interface between
these systems and the TACCO, SENSO, and COTAC
stations. The pilot’s display receives video data from
the DGU only. The SENSO ARU interfaces with the
ADP only.
TELEVISION
Learning Objective: Recognize components
and operating fundamentals of a television
system.
Television can be defined as the transmission and
reception of visual images by means of electrical
signals from one point to another. There are three
basic elements in all television systems. These
elements are as follows:
. A pickup device to convert an optical image
into an electrical signal.
. A means of transmitting that signal from one
point to another.
. A reproducing device to convert the eleclrical
signal into an optical image.
Pickup devices, or camera tubes, include image
orthicons, image isocons, vidicons, plumbicons, and
secondary electron conduction (SEC) tubes.
