ACU = Apron Control Unit Accuracy = The degree of conformance between the estimated or measured position and/or velocity and/or time of/at a platform and its true position and/or velocity and the true time. Radionavigation system accuracy is usually presented as a statistical measure of system error and is specified as: a. Predictable: The accuracy of a position with respect to the geographic or geodetic coordinates of the earth. b. Repeatable: The accuracy with which a user can return to a position whose coordinates have been measured at a previous time with the same navigation system. c. Relative: The accuracy with which a user can determine one position relative to another position regardless of any error in their true positions. In the context of the final approach phase of operation, accuracy may be more generally defined as the ability of the total system to maintain the aircraft position within a total system error (TSE) with a 95 percent probability and to stay within a specified aircraft containment surface which defines the obstacle clearance, terrain avoidance, or aircraft separation criteria for the intended operation. The total system error is based on the 95% probability combination of aircraft and non-aircraft sensor errors, display errors and flight technical errors at each point along the specified procedure. For approach, the outer tunnel must be used as the obstacle clearance surface. |
