Linear Error Probability

urn:aero:airm:1.0.0:ContextualModel:ATMBusinessTerms:Linear_Error_Probability

A linear magnitude within which a stated percentage of measurements for a given point will fall. For example, if the vertical accuracy of a surveyed point is stated as 1 m with 90% LEP, then 90% of measurements of the height of this point will fall along a vertical line of length 1 m. The true position is then estimated to lie at the center of this vertical line.
