horizontal error


Also found in: Acronyms, Encyclopedia.

horizontal error

The 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.

A shallower weapon trajectory would magnify this induced horizontal error.

To see the effect of practice on a pilot's ability to acquire the pathway, a separate analysis of vertical and horizontal error across trials was conducted.
Despite this, the maximum horizontal error calculated by the three GNSS/vehicle dynamic sensors integration algorithms was generally smaller than 10 m during the GNSS outage for 30 seconds.
Vertical error (deviation from 150 feet above ground level) and horizontal error (lateral deviation from a path marked on the ground) were automatically recorded and were used to assess each participant's baseline ability to control the simulator.
For example, if five points were deducted due to 5 horizontal errors, then 51 would be divided by 56 for a percent score of 91.1 for the full mouth series.
