ANNEX III ‘ ANNEX III OCCURRENCES RELATED TO AIR NAVIGATION SERVICES AND FACILITIES Remark : This Annex is structured in such a way that the pertinent occurrences are linked with categories of activities during which they are normally observed, according to experience, to facilitate the reporting of those occurrences. However, this list must not be understood as meaning that occurrences must not be reported when they take place outside the category of activities to which they are linked in the list. 1. AIRCRAFT RELATED OCCURRENCES (1) A collision or a near collision on the ground or in the air, between an aircraft and another aircraft or UAS, terrain or obstacle ( 1 ) , including near-controlled flight into terrain (near CFIT). (2) Separation minima infringement ( 2 ) . (3) Inadequate separation ( 3 ) . (4) Airborne Collision Avoidance System, Resolution Advisory (ACAS RA). (5) Wildlife strike including bird strike. (6) Taxiway or runway excursion. (7) Actual or potential taxiway or runway incursion. (8) Final Approach and Take-off Area (FATO) incursion. (9) Aircraft deviation from Air Traffic Control (ATC) clearance or instructions. (10) Aircraft deviation from applicable Air Traffic Management (ATM) regulation: (a) Aircraft deviation from applicable published ATM procedures; (b) Airspace infringement including unauthorised penetration of airspace; (c) Deviation from aircraft ATM-related equipment carriage and operations, as mandated by applicable regulations. (11) Penetration of the manned aircraft into an active U-space airspace designated inside a controlled airspace. (12) Call sign confusion related occurrences. 2. DEGRADATION OR TOTAL LOSS OF SERVICES OR FUNCTIONS (1) Inability to provide ATM services or to execute ATM functions: (a) Inability to provide air traffic services or to execute air traffic services functions; (b) Inability to provide airspace management services or to execute airspace management functions; (c) Inability to provide air traffic flow management and capacity services or to execute air traffic flow management and capacity functions. (2) Inability to provide or to execute the U-space Dynamic Airspace Reconfiguration (DAR). (3) Missing or significantly incorrect, corrupted, inadequate or misleading information from any support service ( 4 ) , including relating to poor runway surface conditions. (4) Failure of Communication service. (5) Failure of Surveillance service. (6) Failure of Data Processing and Distribution function or service. (7) Failure of Navigation service. (8) Failure of ATM system security which had or could have a direct negative impact on the safe provision of service. (9) Significant Air Traffic Services (ATS) sector / position overload leading to a potential deterioration in service provision. (10) Incorrect receipt or interpretation of significant communications, including lack of understanding of the language used, when this had or could have a direct negative impact on the safe provision of service. (11) Prolonged loss of communication with an aircraft or with other ATS unit. 3. OTHER OCCURRENCES (1) Declaration of an emergency (“MAYDAY”) or state of urgency (“PAN” call). (2) Significant external interference with Air Navigation Services (for example Radio Broadcasts Stations transmitting in the FM band, interfering with Instrument Landing System (ILS), VHF Omni Directional Radio Range (VOR) and communication). (3) Interference with an aircraft, an ATS unit or a radio communication transmission including by firearms, fireworks, flying kites, laser illumination, high powered lights, lasers, Unmanned Aircraft Systems (UAS) or by similar means. (4) Fuel dumping. (5) Abnormal behaviour of a system due to an information security incident (example: compromised information or data, malware infection, Distributed-Denial-of-Service (DDoS)). (6) Fatigue impacting or potentially impacting the ability to perform safely the air navigation or air traffic duties. (7) Any occurrence where the human performance has directly contributed to or could have contributed to an accident or a serious incident. (8) Bomb threat or hijack (applicable until 31 December 2027). ’ ( 1 ) Obstacle includes vehicle. ( 2 ) This refers to a situation in which prescribed separation minima were not maintained between aircraft or between aircraft and airspace to which separation minima is prescribed. ( 3 ) In the absence of prescribed separation minima, a situation in which aircraft were perceived to pass too close to each other for pilots to ensure safe separation. ( 4 ) For example: Air Traffic Services (ATS), Automatic Terminal Information Services (ATIS), meteorological services, navigation databases, maps, charts, Aeronautical Information Services (AIS), manuals.
