1. A method of generating an informational profile for guiding an aircraft flight, the method comprising the steps of:

  • a. providing information concerning locations of an earlier position P1 and a later position P4, as well as aircraft first operating parameters for conducting a climb from the earlier position P1 and aircraft second operating parameters for conducting a descent to the later position P4 ;

    b. calculating a location of an upper descent position P3 from the later position P4 as a function of a projected distance to be flown by the aircraft when descending to position P4 in accordance with the aircraft second operating parameters;

    c. calculating a location of an upper climb position P2 from earlier position P1 as a function of a projected distance to be flown by the aircraft when climbing to the upper climb position P2 from position P1 in accordance with the aircraft first operating parameters;

    d. generating the informational profile which is defined by a climb portion including positions P1 and P2, a descent portion including positions P3 and P4, and an intermediate portion including positions P2 and P3 ; and

    e. guiding said aircraft based on the generated informational profile.
