Abstract:
1. An on-board flight strategy evaluation system aboard an aircraft, linked to an aircraft flight plan, comprising: calculation circuitry configured to determine relations between flight parameters, including parameters of time, of fuel quantity, of altitude and of speed, by establishing correlations between transit time and a quantity of fuel at waypoints in said flight plan according to different profiles of speed and altitude, and interface circuitry configured to provide at least one envelope of values of said flight parameters at at least one reference point among said waypoints, said at least one envelope of values being representative of a definition domain of a plurality of flight strategies, provide at least one determined strategy defined by the determined values assumed by said flight parameters at said at least one reference point, allow selection and setting of a value of a first flight parameter among said flight parameters to generate and supply another envelope of values of said flight parameters, to allow exploration of another plurality of possible flight strategies, and allow selection and setting of a value of a second flight parameter, in addition to said first flight parameter, to generate and supply another determined flight strategy.
