Abstract: The sustained increase of the air transportation sector over the last decades has led to traffic saturated situations, inducing higher costs for airlines and important negative impacts for airport surrounding communities. The efficient management of air traffic supposes that aircraft trajectories are fully mastered and their impacts can be accurately forecasted. Inversion of aircraft flight dynamics, which are essentially nonlinear, appears necessary. Aircraft flight dynamics is shown to be differentially flat, which is a property that I has enabled the development of new numerical tools for the management of complex nonlinear dvnamic systems. I However, since in the case of aircraft flight dynamics this differential flatness property is implicit, a neural I network is introduced to deal with its numerical inversion. Results related to the developed neural network I training are displaved, while potential uses of the proposed tool are discussed.
