Conformance monitoring in air traffic control is an approach that is used to detect any deviations of the aircraft from its cleared (or planned) flight path that might compromise safety and efficiency. This task is made difficult by the fact that some deviations are normally expected of a conforming aircraft due to uncertainties. In this paper, a conformance monitoring algorithm that uses a stochastic linear hybrid system model is proposed. The stochastic linear hybrid system model divides the aircraft dynamics into a number of flight modes and is able to describe the random deviations in (conforming) aircraft trajectories. The detection of any nonconforming trajectories is determined by a fault detection technique. First, a hybrid estimation algorithm is used to estimate the hybrid state of the stochastic linear hybrid system and generate a residual vector based on the measurements. The statistical characteristics of the residual expected of a conforming aircraft are derived. Then, a statistical decision testis used to detect any deviation of the observed residual from the expected residual. Two illustrative examples are presented to demonstrate the performance of the proposed algorithm.
