Conformance monitoring approaches in current and future air traffic control environments

Conformance monitoring is of fundamental importance to ATC operations and future surveillance environments may enable more sophisticated procedures to be developed for this task. A Conformance Monitoring Analysis Framework has been presented which enables model-based fault detection and isolation techniques to be employed to investigate many important issues. The essential concepts of Conformance Residual generation; decision-making and intent inferencing have been identified and a lateral trajectory case study using a very simple Conformance Monitoring Model has been used to illustrate the promise of this approach for investigating different state environments. Preliminary results indicate potential improved time-to-detection performance associated with using relevant higher order states in addition to position, but this is at the expense of greater noise in the Conformance Residual.
