The key risk areas of UAS operations have been identified by EASA through analysis of the reported occurrences in the ECCAIRS database involving UAS operation analysis.
Airborne Conflict
Airborne conflict in the context of UAS specifically covers the risk of airborne collision between a drone and an aircraft in the air. This key risk area accounts for Mid Air Collision/Airprox and Navigation occurrences as well as safety occurrences related to ATM/ANS. Further details about the key risk area are provided in Chapter 10 of the analysis.
