摘要
Methods and systems for optimizing the flight of an aircraft are disclosed. The trajectory is partitioned into segments, each of the segments being governed by sets of distinct equations, which are a function of the engine thrust mode and of the vertical guidance (ascent, cruise or descent). Assuming two models, aerodynamics and engine speed, data from flight recordings are received and a number of parameters of a parametric optimization engine is iteratively determined by applying a least squares calculation until satisfaction a predefined minimum criterion. The parametric optimization engine is then used to predict the trajectory point according to a given point. Software and system aspects (e.g. FMS and / or EFB) are described.
