On radar display areas with dense traffic the labels associated with the aircraft tracks may overlap with each other or with track symbols. This phenomenon reduces significantly the readability of the labels. In case labels are overlapping tracks safety may be affected. In the past different approaches to overcome the overlapping problem by automation have been realized. Today, none of them provides acceptable anti-overlapping functionality.
In opposite to previous approaches the study attacks the overlapping problem with a local approach. Local means local to each aircraft displayed on the screen. The local area for the research for de-conflicting labels covers the reasonable distance to the track where a label should be. The study model preferences and constraints for the label position by different weightings in a mathematical formula. A research algorithm search then the best possible new labels position starting from the previous label position. This approach is very flexible and may include any weighted constraint model. The local approach allows distributed computing for the of the label anti-overlapping problem.
