AN/APG – 68 (V5) Operations Guide

Range
The final control that you can use with the radar is the range setting.
This adjusts the display to show only targets that are within a certain
range. This control does NOT reduce the power of the radar, and so
does not reduce your chance of being detected by enemy forces
electronic warning systems. The current maximum range is display
on the top left of the display. The (F3 & F4) keys decrease and
increase radar range respectively.
Target Acquisition Cursor
The Target Acquisition Cursors (TAC) are the main method
that is used to designate and find out information about
contacts whilst using the radar. It appears as two small bars in
the radar screen (shown left). The bars themselves are there
to allow you to investigate a contact further by ‘bugging’ it
(this tells the radar to pay more attention to this contact). The
UA, and LA shown left are indicative of the upper and lower altitude limits
that the radar is scanning at that spot.
Search Altitude Display
The search altitude display appears underneath the contact symbol
whenever the Target Acquisition Cursors are over that contact. This
number indicates the contacts altitude in thousands of feet. (e.g. 07
= 7000ft, 10 = 10,000ft, 25 = 25,000ft).
Attitude Indicator
The radar display also has an aircraft attitude display, these ‘wings’ in the
radar can be used to judge you pitch and roll relative to the horizon. When
the wings are parallel to the bottom and top of the radar screen you are
level. The ‘wings’ will also move up and down the display to give you
information on aircraft pitch. This can be referenced with the range markers
on the right hand side of the display, and indicate 30 of pitch for each tick
mark. When
