ENR 1.14 Air traffic incidents
1 Definition of air traffic incidents
The term “ATI - Air traffic incident” is used to
mean a serious occurrence related to the provision of air traffic
services, such as:
- aircraft proximity (AIRPROX);
- serious difficulty caused by:
- faulty procedures or lack of compliance with applicable procedures or
- failure of ground facilities.
1.1 Aircraft Proximity
Aircraft proximity is a situation in which, in the opinion of the pilot or ATS personnel, the distance between aircraft, as well as their relative positions and speed, has been such that the safety of the aircraft involved may have been compromised.
1.2 ATI - Air Traffic Incidents are designated and identified in reports as follows:
| Type | Designation |
|---|---|
| Air traffic incident | Incident |
| as a) above | Aircraft proximity) |
| as b) 1) above | Procedural |
| as b) 2) above | Facility |
2 Use of the Air Traffic Incident Report Form - ATIR
ATI which occurs in connection with Air Traffic Control Service require notification in writing by means of the Air Traffic Incident Report Form.
2.1 The Air Traffic
Incident Report Form is intended for use:
- by a pilot for filing a report on an ATI after arrival or for confirm a report made initially by radio during flight;
- by an ATS unit for recording an ATIR received by radio, telephone or teleprinter;
- by an ATC unit for filling a report on an ATI caused by an aircraft violating provisions or an ATC clearance.
2.2 The duty of
notification is obligatory for the aeronautical personnel involved
as well as the units of air navigation services.
2.3 When a pilot or
appropriate ATC unit
intends to submit an ATIR, the appropriate data must be supplied in
advance by radio, without indicating personal data such as name or
address. This initial radio advisory should include all essential
information, such as: call sign, date and time of incident, position
information, heading, route, airspeed and altitude and if another
aircraft is involved its description. In the case that in the
opinion of parties involved a risk of collision exists this should
be clearly stated.
2.4 A collision risk
exists in case of aircraft proximity, when avoidance manoeuvre was
required or appropriate to prevent a collision or an unsafe
situation. Such cases will be investigated by the Aircraft Incident
Investigation Commission (AIIC). All other cases will be
investigated by the appropriate ATC unit and Ministry of
Transport, Civil Aviation Directorate (DCA). AIIC will be
periodically informed about the results of the investigations and
actions taken.
2.5 The ATIR for
incidents having occurred in Slovenia or abroad should be addressed
in writing to:
| Post: | Ministry of Transport Civil Aviation Directorate (DCA) Langusova 4 SI-1535 Ljubljana SLOVENIA |
2.6 or to the ARO in the Aerodrome of first landing for
submission to the above address.
3 Purpose of reporting and handling of the form
3.1 The purpose of
the reporting ATIR is to promote the safety of aircraft and to
provide the investigation authorities with as complete information
on an ATI as possible and to enable them to report back, with the
least possible delay to the pilot or operator concerned, the result
of the investigation of the incident and if appropriate, the
remedial action taken.
