EUROCONTROL Specification for Monitoring aids (MONA)

This EUROCONTROL Specification provides system requirements for Monitoring Aids (MONA). The purpose of MONA is to assist the controller in the routine monitoring of the traffic situation, warning the controller when aircraft deviate from their planned route or clearances, reminding the controller of actions that need to be performed, and keeping the trajectories updated with the progress of the flights. The document describes objectives to be achieved and system requirements describing a behaviour of the system that achieves the objectives.
