The paper presents methods to determine the time, positions and distance of closest approach for two aircraft following arbitrary trajectories in two or three dimensions. Three examples are given: (i) two aircraft changing the modulus of the velocity of one of them; (ii) two aircraft changing the climb rate of one of them; (iii) one aircraft straight and one aircraft curved trajectory.
