CHAPTER THREE T-<strong>45</strong> <strong>WEAPONS</strong>/<strong>STRIKE</strong><br />

Figure 3-3 Aim Off Distance / Point / Angle<br />

10. Aim-Off Distance. The distance measured from the target to a point the flight path<br />

intersects the ground.<br />

11. Aim-Off Point. A ground feature or point on the ground that represents the aim off<br />

distance.<br />

12. Aim-Off Angle. The angle created between the flight path angle and line of sight to the<br />

target.<br />

13. Target Depression Angle. The angle created between the horizon and line of sight to the<br />

target. It is the number of degrees the target is depressed below the horizon, the sum of the flight<br />

path angle and target placement angle.<br />

14. Target Placement Angle (TPA). The angle between the flight path and the line of sight to<br />

the target derived for checkpoint altitude. Ensuring the TPA is set at checkpoint altitude will<br />

provide a reasonable weapons solution very close to planned release altitude. If the aircraft is on<br />

the bombing triangle, setting the TPA results in the Velocity Vector overlaying the Aim-Off<br />

Point.<br />
