This study proposes a two‐step solution approach for aircraft conflict resolution and fuel
consumption due to resolution maneuver occurring in free‐route airspace. This model aims …

In a short period since South-East Axis Free Route Airspace (SEAFRA) and Slovenian

Aircraft fly en route under concurrent event situations (conflicting situations), which occur
when they operate in the same airspace but are too close to each other in the same time …

Aircraft conflict resolution is of great importance for the safe and efficient management of air
