5. Plotting peculiarities of the AN/AVQ-26 pave tack reconnaissance sensor. To plot pave
tack imagery is almost impossible. The imagery produced by the pave tack system is a
continuous strip with no break in the flow of the imagery. The moveable sensor will produce
imagery from every direction from forward or rearward oblique, to left or right high or low
oblique, to panoramic to vertical.
PART B: INFRARED PLOTTING METHODS
1.
There are two methods that can be used when plotting an IR mission.
a.
Plotting method 1, plotting identifiable features. Identify features on the extreme
edges of the imagery that appear on the map. Make small tick marks at these locations on the
overlay paper over the map. Then, using a straightedge or French curve, connect the tick
marks and enclose the area covered by the IR imagery (Figure 2-6).

on both Map and Imagery.
b.
Plotting method 2, mathematical computation from the nadir. When detail is lacking
along the edges of the imagery, draw an imaginary line down the center of the imagery, which
will represent the nadir or flight path directly below the aircraft. Next, compare details along
the imaginary line to details on the map. Using the scan angle for each side of the nadir, plot
the area covered by the mission (Figure 2-7).
