of the weapon. The effect of changing each parameter will now be considered. The following
factors are discussed from a perspective of using a Depressed Sight Line (DSL) pipper in the
T-45C manual (MAN) bombing mode.
Dive Angle
Deviations from planned dive angle will also cause a false sight picture. A steep dive will cause a
long hit and a shallow dive a short one. Changing the dive angle will change the extent to which
gravity will bend the weapon trajectory below the line of flight. Suppose you release a weapon at
a dive angle of 90 degrees. Since gravity works straight down, there will be no effect on the
trajectory. You can see that a steeper angle requires a smaller mil setting; if you release steep,
your mil setting is too large and the bomb will strike beyond the target. If you are shallow, you
need a greater mil setting, just as you do for a shallow pattern, and your hit will be short.

Airspeed
Figure 3-11 Dive Angle Error
Any deviation from planned release airspeed will cause a false sight picture. For example, a fast
release will decrease your AOA and bring the pipper short of the impact point causing a long hit.
A slow release will show the pipper long and cause a short hit. Airspeed also has an effect on the
weapon time of fall. (Figure 3-12)
