1. A method of constructing a vertical profile for an aircraft descent and/or approach, the method comprising a first set of steps and a second set of steps, the first set of steps using values of a plurality of reference parameters, the first set of steps comprising:
providing, for at least one of a plurality of red to as strategic parameters, a value relating to a user strategy, said strategic parameters corresponding to at least some of said reference parameters, the values of a parameter corresponding to all the possible options offered for setting this parameter; and in automatically constructing said vertical profile using the value thus provided, the method additionally comprising a second set of steps carried out during a flight of the aircraft and comprising: a) presenting the crew of the aircraft with the values of a plurality of parameters referred to as tactical parameters, which have been used to calculate the vertical profile, the tactical parameters corresponding to at least some of said reference parameters; b) modifying at least one of said tactical-parameter values presented in step a); and c) automatically reconstructing the vertical profile using the value modified in step b). |
