T-45 WEAPONS/STRIKE CHAPTER THREE
G at Release
Proper g at release depends on dive angle. For a 30-degree delivery, about 0.87 g is required to
maintain a straight flight path. A 10-degree dive requires almost 1 g. A 60-degree dive (not used
in the training command) would require only 0.5 g. The mil setting for each type of delivery is
valid only at the proper g. Incorrect g at release will change the angle of attack of the ADL and
will invalidate your mil setting by causing a false sight picture. Excessive g will cause an early
sight picture. So, if you apply excessive g to obtain the proper sight picture and have all other
parameters correct, your hit will be short. Insufficient g will cause a long hit. In addition,
incorrect g will have another undesirable effect—changing your dive angle. Proper g results in a
straight flight path and a constant dive angle. Too much g will shallow the dive angle, and
insufficient g will steepen it.
By simply maintaining the Velocity Vector on a specific angle will result in the proper g at
release. Common error in weapons delivery is not being properly trimmed for release and
allowing the Velocity Vector to “creep” up as the aircraft seeks 1.0g flight.
Factors Affecting Trajectory
Figure 3-10 G at Release
For each type of weapons run you make, you will have a mil setting, which will compensate for
the extent to which a weapon will drop below your aircraft flight path. Each mil setting is
calculated so that if you release your weapon at the proper altitude, with correct airspeed, dive
angle, and g, with wings level, zero yaw, and the pipper on the target, the weapon will hit the
target, assuming no wind. However, a change in any of these parameters will affect the trajectory
