- an aircraft can be any type of aircraft such as an airplane, a helicopter, a hot air balloon, or a drone.

- a degree of relevance of proposing a resolution of the air conflict can be determined as a function of the category of the air conflict detected and of the air situation. The degree of relevance determines whether it is relevant to propose a resolution to the air conflict given the air situation at the time the air conflict is detected and the data of the air conflict.

If it is determined in step 103 that it is not relevant to propose a resolution of the air conflict detected, steps 108 to 109 can be carried out.
