1. A method for guiding a descent of an aircraft, the method comprising the steps of:

  • a. determining a position of the aircraft and providing a first output corresponding to the position;

    b. inputting information representing a lower descent position P0 as well as first and second aircraft descent parameters for conducting said descent;

    c. generating a descent guideslope which is formed by at least upper and lower descent legs, in which the lower descent leg includes the lower descent position P0 and an upper descent position P1, and the upper descent leg includes the upper descent position P1 and a further upper descent position P2, in a manner that a location of the upper descent position P1 relative to the lower descent position P0 is calculated as a function of the first descent parameters, and a location of the further upper descent position P2 relative to the upper descent position P1 is calculated as a function of the second descent parameters; and

    d. guiding the aircraft in response to the first output and the descent guideslope.
