Definition

A degree of conformance between the estimated or measured value and the true value.

Definition Source

ICAO, official definition, added to An 11 by Amdt 37 (1997), to An 14/I & 14/II by Amdt 2 (06/11/1997) and to An 15 by Amdt 29 (06/11/1997).

Note

For measured positional data the accuracy is normally expressed in terms of a distance from a stated position within which there is a defined confidence of the true position falling.
