Conflict (air traffic control)

from Wikipedia, the free encyclopedia

In air traffic control, a conflict is a situation in which two or more aircraft are on a collision course . A distinction is made between local and opposite conflicts. Both are determined with the help of so-called "flight strips".

Local conflict

At least two aircraft are involved in a local conflict . There is a point on the route of all aircraft involved where the following conditions apply:

  • Your time interval when you fly over the point is four minutes or less.
  • Your spatial height distance is 30 flight levels ( flight level , FL ) or less.

Opposite conflict

Opposite conflicts arise when the following conditions are met:

  • At least two planes come towards each other between two points (e.g. one plane flies from city A to B, the other plane from B to A).
  • Due to varying elevation changes over the course of the flight, the vertical elevation separation between the aircraft is less than or equal to 30 FL at any one time.

These conflicts are discovered by so-called data assistants who use flight strips to check flight routes for conflicts.
