Accounting Management enables charges to be established for the use of resources, and for costs to be identified for the use of those resources. Accounting management includes functions to inform users of costs incurred or resources consumed, enable accounting limits to be set and tariff schedules to be associated with the use of resources, and enable costs to be combined where multiple resources are invoked to achieve a given communications objective. Accuracy Accuracy of own performance on the tasks with the aid of the adaptive automation. The degree of conformance between the estimated or measured position and/or velocity and/or time flat a platform and its true position and/or velocity and the true time. Radio navigation system accuracy is usually presented as a statistical measure of system error and is specified as: a) Predictable -the accuracy of a radio navigation system's position solution with respect to the chartered solution. Both the position solution and the chart must be based upon the same geodetic datum. B) Repeatable - the accuracy with which a user can return to a position whose co-ordinates have been measured at a previous time with the same navigation system. C) Relative - the accuracy with which a user can measure position relative to that of another user of the same navigation system at the same time. Achieved Warning Time The actual warning time provided by the alert. Acknowledge(ment) message Notification that a given communication has been correctly received and understood. Acknowledgement Controller sourced message that is associated with a previous non-conformance warning or reminder message. Although these messages may serve to signify the controller’s recognition of the warned or reminded situation - the use of such messages will depend on particular cases. Across Track Acceleration The product of the value of the Ground Speed and the time derivative of the Course Angle. Action Intentional or goal-directed behaviour. Active Advisory Horizon The lead time (VSP) before the estimated time of arrival at the constraint point. The flight is sequenced and advisories are issued. Active Mode of Real-Time Civil/Military Co-ordination Is the communication mode in real-time between civil and military units which results from an action by the controller(s). Active NOTAM A NOTAM is active between the date-times stated in Items B and C taking into account the time sche-duled in Item D. Active Plan Individual or specific item plan derived from a business or strategic plan.
