A system may generate a modified flight plan for an aircraft based on an original flight plan. The system may provide an automatic strategic offset function that includes an autoflight system; a sensor system including at least one of a global positioning system, an inertial reference unit, or an air data computer; and a flight management computer. The flight management computer may be operably coupled with the autoflight system and/or the sensor system. The flight management computer may process a flight plan of the vehicle and generate a non-uniform offset value in the vertical and/or lateral orientation between the flight plan and a boundary. The offset value may be used to create an offset flight plan for navigating an aircraft.
