Figure 8-37 Setting the Correct TPA<br />

In our example above, the Sight Angle is 128 mils. With the pipper being 42 mils below the<br />

target results in 86 mils above the target.<br />

There are 17.<strong>45</strong> mils per degree. 86 mils / 17.<strong>45</strong> = 4.9 or 5 degrees. So then, by placing the<br />

Velocity Vector 5 degrees above the target results in the pipper 42 mils below the aimpoint.<br />

If we set more than 5 degrees (>TPA) above the target, it will result in the pipper being less<br />

than 42 mils from the aimpoint, causing the pipper to arrive at the aimpoint earlier than planned<br />

(i.e. less tracking time, early sight picture) or higher than planned.<br />

If we set less than 5 degrees (
