First Claim
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.

Abstract
Systems and methods for aircraft guidance using a localizer capture criteria for rectilinear displacement data are disclosed. In one embodiment, the method includes determining a rectilinear deviation D between a current aircraft location and a final defined path (FDP) of an aircraft and determining a location at which the aircraft should begin a reposition maneuver based on the rectilinear deviation D. The method starts a reposition maneuver of the aircraft at a location determined based on a relationship between D and characteristics of the aircraft during the reposition maneuver. In some embodiments, the characteristics of the aircraft may include a velocity of the aircraft with respect to ground, an aircraft track angle, a heading of the FDP of the aircraft, a maximum allowed bank angle of the aircraft during a reposition maneuver, and a time allowance for aircraft rollup and rollout.
