Abstract: Aircraft separation is a critical operation for safe and efficient flight operations. It can be maintained in en-route flight phase using heading angle change (HAC), speed change (SC) or altitude change (AC) manoeuvres. Besides, a commonly preferred HAC method is known as vector manoeuvre, which can also be combined with SC manoeuvre. In this study, the multi-objective nonlinear programming optimisation model is presented for the vector manoeuvre to minimise both fuel consumption and vector manoeuvre distance together. To achieve this, the weighted sum approach method was implemented to the proposed model to obtain Pareto-optimal solutions. The results showed that the optimisation model was able to obtain between 15 and 45 different Pareto-optimal solutions regarding the conflict resolution distance.

Keywords: aircraft conflict resolution problem; aircraft vector manoeuvre; nonlinear programming model; air traffic management; multi-objective optimisation; heading angle change; HAC.
