horizontal error
horizontal errorThe error in range, deflection, or in radius, which a weapon may be expected to exceed as often as not. Horizontal error of weapons making a nearly vertical approach to the target is described in terms of circular error probable. Horizontal error of weapons producing elliptical dispersion pattern is expressed in terms of probable error. See also circular error probable; delivery error; deviation; dispersion error.horizontal error

The horizontal error of weapons making a nearly vertical approach to the target is described in terms of circular error probability. The horizontal error of weapons producing an elliptical dispersion pattern is expressed in terms of probable error.AcronymsSeeHe |
