ERROR CORRECTIONS DURING RUN
The previous section described what should happen during an ideal run. In practice, you will find that it
is difficult to achieve an ideal run. Although you must strive to arrive at the release point with proper
airspeed, dive angle, and so on, you will frequently find that at least one of your delivery parameters is in
error. In such a case, if you simply continue the run and release at normal altitude, you will miss the
target. In the Training Command, you have the option of aborting the run and trying again. In a combat
environment, however, you normally get just one chance. Even on a training flight there is a limit to the
number of runs you can abort and still expend all your ordnance within the allotted target time. There-
fore, you must learn to make corrections during your run for each type of error that can occur.
ERROR SENSITIVITIES
In order to make proper corrections, you must know how much each error will affect your accuracy. We
have already discussed in general terms the effects of deviating from each of the various parameters
such as airspeed, dive angle and altitude. For example, we showed that a dive angle steeper than
planned will cause a long hit, so releasing high can compensate for a steep dive angle. However, in
order to actually make such a correction, you must know how high to release to compensate for each
degree you are steep. In other words, for each type of run, you must know exactly how dive angle,
airspeed, and altitude affect accuracy, and how they relate to one another. The table (Figure 20) sum-
marizes this information and should be memorized.
This table shows, for example, that a 1-degree error in dive angle in a 30-degree bomb run will cause
your hit to be 50 ft long or short, and that a 10-kt airspeed error will have the same effect. How these
relationships can be used in a run will be discussed below.
