Abstract: A method for optimizing the trajectory of an aircraft comprises the steps of determining one or more reference criteria CiRef on the basis of a non-optimized initial trajectory; determining one or more initial constraints K′j on the basis of the initial trajectory; determining a criterion Ci according to an analytical function of the criteria CiRef; and, per iteration cycle, determining an optimized trajectory; determining intermediate constraints K′j on the basis of the optimized trajectory; minimizing the criterion Ci determined under the initial constraints K′j and the intermediate constraints K′j; determining q takeoff parameters Pi. Developments describe an incremental iteration of the method, an interruption by the pilot, the use of criteria comprising the fuel consumption, the acoustic noise level, the emission of chemical compounds, the level of wear of the engine, the use of a gradient descent and of diverse optimizations. System and software aspects are described.

Abstract: A method for creating a vertical trajectory profile of an aircraft by optimization of a criterion representative of a flight cost, comprises: performing a first iterative computation of a profile free of altitude constraints as long as a condition dependent on the criterion is not reached, replacing each free level of the constraint-free profile with a permitted level so as to generate an initial constrained profile comprising a plurality of permitted levels, and, for each level, an altitude change point and a plurality of speeds, and performing a second iterative computation of a profile in which the altitude levels to be reached remain constant, equal to the initial permitted levels of the initial constrained profile, as long as a condition dependent on the criterion is not reached.
