The graph mainly shows the maximum mesh distance of 012 aircraft during the
whole simulation process. From the initial parameter setting, it is known that collision
will occur in the 20th simulation cycle. It can be seen from the figure that the safety
Formula (1) is satisfied by any two aircraft in the 20th step of collision prediction, i.e.,
the flight safety interval requirement. The distance of their real trajectory is shown in
Fig. 9.
