Randomized Algorithms for Probabilistic Aircraft Conflict Detection
نویسندگان
چکیده
A mid-range conflict alerting system is proposed, based on a measure of criticality which directly takes into account the uncertainty in the prediction of the aircraft positions. The use of randomized algorithms makes the computation of the criticality measure tractable. The performance of the algorithm is evaluated by Monte Carlo simulation on a stochastic ODE model of the aircraft motion.

Based on the trajectory prediction error model proposed by Paielli and Erzberger, we propose nominal and probabilistic conflict detection algorithms using flight mode estimates as well as the aircraft current state estimates. This is different from previous conflict detection algorithms which use current state estimates only. Our algorithms are therefore based on hybrid models of aircraft, whic...

In this deliverable we study algorithms for mid-term aircraft conflict detection. A twoaircraft conflict occurs when some prescribed separation distance between two aircraft is violated. In a mid-term time scale, the contribution of the different sources of uncertainty affecting the aircraft motion cannot be neglected when predicting the aircraft future positions. Based on this consideration, w...

In this paper we describe a general connict detection/resolution scheme for a pair of aircraft ying at the same altitude, focusing on the connict detection component. The proposed approach is formulated in a probabilistic framework, thus allowing uncertainty in the aircraft positions to be explicitly taken into account when detecting a potential connict. The computational issues involved in the...
متن کاملA probabilistic approach to aircraft conflict detection
In this paper, we concentrate primarily on the detection component of conflict detection and resolution schemes operating at the mid-range and short range level of the air traffic management process. Probabilistic models for mid-term and short term prediction are introduced. Based on the mid-term prediction model, the maximum instantaneous probability of conflict is proposed as criticality meas...
