What correction is needed when there are no airbursts observed during precision registration?

When conducting precision registration, the objective is to achieve precise impacts on a target using artillery fire. In the context of this question, if no airbursts are observed during the registration process, it indicates that the rounds are likely hitting below the intended target area due to insufficient elevation. However, in this specific situation, it is crucial to understand that the absence of airbursts does not necessitate an immediate elevation adjustment.

The correct choice emphasizes that when there are no airbursts observed, it typically signifies that the rounds are correctly descending into the target and that the registration process has not indicated the need for further adjustment at that moment. Therefore, no correction would be required if the impacts are still effective or if the goal is to maintain that specific point of impact for accuracy in subsequent fire missions.

In practice, if no airbursts are observed, it does not automatically prompt an elevation increase since it indicates that the current firing data is stable and not causing undue deviation from the target. Thus, maintaining the current settings is appropriate until further information suggests otherwise.
