ENR 1.14   AIR TRAFFIC INCIDENTS

1   Definition of air traffic incidents

1.1  "Air traffic incident" is used to mean a serious occurrence related to the provision of air traffic services, such as:
  1. aircraft proximity (AIRPROX) ;

  2. serious difficulty resulting in a hazard to aircraft caused, for example, by:

    1. runway incursion

    2. obstruction on runway

    3. faulty procedures

    4. non-compliance with procedures, or

    5. failure of ground facilities.

1.1.1  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 compromised. 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 compromised.

No risk of collision

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

Risk not determined

The risk classification of aircraft proximity in which insufficient information was available to determine the risk involved, or inconclusive or conflicting evidence precluded such determination.

AIRPROX

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

1.2  Air traffic incidents are designated and identified in reports as follows:

2   Use of the Air Traffic Incident Report Form (See model on pages ENR 1.14-3 to 1.14-5)

The Air Traffic Incident Report Form is intended for use: by a pilot for fling a report on an air traffic incident after arrival of for confirming a report made initially by radio during flight.

Note - The form, if available on board, may also be used in making an initial report in flight or as the format for the text of a message to be transmitted over the AFS network.

3   Reporting procedures(including in-flight procedures)

3.1  The following are the procedures to be followed by a pilot who is or has been involved in an incident:
  1. during flight, use the appropriate air to ground frequency for reporting an incident of major significance, particularly if it involves other aircraft, so as to ascertained immediately;

  2. as promptly as possible after landing, 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 had not been possible to report it by radio;

    2. for reporting an incident which did not require immediate notification at the time of occurrence.

3.2  An initial report made by radio should contain the following information:
  1. aircraft identification;

  2. type of incident, e.g. aircraft proximity;

  3. - 1. a) & b)

    - 2. a), b), c), d), n)

    - 3. a), b), c), i)

    - 4. a), b)

  4. miscellaneous: 1. e).

3.3  The confirmatory report on an incident of major significance initially reported by radio or the initial report on any other incident should be submitted to Ministry of Land, Infrastructure and Transport. The pilot should complete the Air Traffic Incident Report Form, supplementing the details of the initial reports as necessary.

4   Purpose of reporting and handling of form

4.1  The purpose of the reporting of aircraft proximity incidents and their investigation is to promote the safety of aircraft. The degree of risk involved in an aircraft proximity incident should be determined in the incident investigation and classified as "risk of collision", "safety not assured", "no risk of collision" or "risk not determined"
4.2  The purpose of the form is to provide investigatory authorities with as complete information on an air traffic incident as possible and to enable them to report back, with the least possible delay to pilot or operator concerned, the result of the investigation of the incident and, if appropriate, the remedial action taken.
