1. A method to provide aircraft guidance, comprising:

  • determining a first flight trajectory for a first aircraft;

    determining a second flight trajectory for a second aircraft;

    determining a predicted first distance between the first aircraft and the second aircraft at a first closest point of approach based on the first and second flight trajectories;

    comparing the predicted first distance to a first separation perimeter, the first separation perimeter to define a first three-dimensional perimeter based on the first aircraft;

    determining a first flight trajectory adjustment having a first magnitude from the first flight trajectory when the predicted first distance is within the first separation perimeter;

    determining a second flight trajectory adjustment having a second magnitude from the first flight trajectory when the predicted first distance is within a second separation perimeter different from the first separation perimeter; and

    altering the first flight trajectory based on the first flight trajectory adjustment or the second flight trajectory adjustment.
