摘要
A method for assisting in the flight management of an aircraft calculates a local operating cost function CF(xi, hj) at various altitudes hj along a planned reference flight trajectory over a discrete set of points P(xi, hj) which forms a two-dimensional grid in which the planned vertical reference flight trajectory varies, the local cost function CF(xi, hj) being calculated locally at each point P(xi, hj) according to aircraft data and environmental data predicted at said local point P(xi, hj). Then, for each point P(xi, hj) of the grid, the method determines a neighbourhood including the point P(xi, hj), and associates a colour K(xi, hj) therewith that is dependent on the value of the local cost function CF(xi, hj) using a predetermined bijective lookup transformation. Next, the method displays the coloured grid formed by the coloured neighbourhoods. The method is implemented in an onboard flight management avionics system, in an onboard tablet of EFB type, in a ground tool of the operator which is interfaced with the onboard flight management system, or by distribution over the three types of systems.
