1. A method for guiding an aircraft, the method comprising:

  • determining a rectilinear deviation D between a current aircraft location and a final defined path (FDP) of the aircraft;

    determining a location for the aircraft to begin a reposition maneuver based at least in part on the rectilinear deviation D and a relationship between the rectilinear deviation D and characteristics of the aircraft, the characteristics of the aircraft are selected from the group of characteristics comprising;

    a velocity of the aircraft with respect to ground (Vel_Gnd), an aircraft track angle, a heading of the FDP of the aircraft, a maximum allowed bank angle of the aircraft during a reposition maneuver (Phimax), and a time allowance for aircraft rollup and rollout (Capt_Rup_KPg); and

    starting the reposition maneuver of the aircraft at the location.
