1   DEFINITION OF AIR TRAFFIC INCIDENTS

1. Aircraft proximity (AIRPROX),
2. serious difficulty resulting in a hazard to aircraft caused, for example, by:
   1. faulty procedures,
   2. non-compliance with procedures, or
   3. failure of ground facilities.

Definitions for aircraft proximity and AIRPROX.

Aircraft proximity
A situation in which, in the opinion of the pilot or the air traffic services 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 jeopardised. Aircraft proximity is classified as follows:

Risk of collision
The risk classification of aircraft proximity in which serious risk of collision has existed.

Safety not assured
The risk classification of aircraft proximity in which the safety of the aircraft may have been jeopardised.

No risk of collision
The risk classification of aircraft proximity in which no risk of collision has existed.

Risk not determined
The risk classification of aircraft proximity in which insufficient information is available to determine the risk involved, or inconclusive or conflicting evidence precludes such determination.

AIRPROX
The code word used in an air traffic incident report to designate aircraft proximity.

2   USE OF THE “AIR TRAFFIC INCIDENT REPORT FORM” (See model on Fig. 1)

The “Air Traffic Incident Report Form” is intended to be used:

1. by a pilot for filing a report on an air traffic incident after arrival or for confirming a report made initially by radio during the flight.

   Note.

   The form, if available on board, may also be used in providing a pattern for making the initial report in flight.

2. by an ATS unit for recording an air traffic incident report received by radio, telephone or fax.

   Note.

   The form may be used as the format for the text of a message to be transmitted over the AFS network.

3   REPORTING PROCEDURES (INCLUDING INFLIGHT PROCEDURES)

1. during flight, to use the appropriate air/ground frequency for reporting an incident of major significance, particularly if it involves other aircraft, so as to permit the facts to be ascertained immediately;
2. as promptly as possible after landing, to submit a completed “Air Traffic Incident Report Form”:
   1. for confirming a report of an incident made initially as in a) above, or for making the initial report on such an incident if it was not possible to report it by radio,
   2. for reporting an incident which did not require immediate notification at the time of occurrence.

1. aircraft identification;
2. type of incident, e.g. aircraft proximity;
3. the incident: 1. a) and b); 2. a), b), c), d), n); 3. a), b), c), i); 4. a), b);
4. miscellaneous: 1. e).

or to the Vilnius ARO of the aerodrome of first landing for submission to Lithuanian Transport Safety Administration. The pilot should fill in the “Air Traffic Incident Report Form”, supplementing the details of the initial reports as necessary.
