# SERA.7002 Collision hazard information when ATS based on surveillance are provided

ANNEX: Rules of the Air · Regulation (EU) No 923/2012 · EAR revision 26 Aug 2025

IR Implementing rule

## SERA.7002 Collision hazard information when ATS based on surveillance are provided

(a) When an identified [controlled flight](https://avioverse.aero/glossary/easa/controlled-flight) is observed to be on a conflicting path with an unknown [aircraft](https://avioverse.aero/glossary/easa/aircraft), deemed to constitute a collision hazard, the pilot of the controlled flight shall, whenever practicable:

(1) be informed of the unknown aircraft, and, if the pilot so requests, or if the situation so warrants in the opinion of the controller, avoiding action shall be suggested; and

(2) be notified when the conflict no longer exists.

AMC Acceptable means of compliance

## AMC1 SERA.7002(a)(1) Collision hazard information when ATS based on surveillance are provided

INFORMATION REGARDING TRAFFIC ON CONFLICTING PATH

(a) Information regarding traffic on a conflicting path should be given, whenever practicable, in the following form:

(1) relative bearing of the conflicting traffic in terms of the 12-hour clock;

(2) distance from the conflicting traffic in kilometres or nautical miles;

(3) direction in which the conflicting traffic appears to be proceeding; and

(4) [level](https://avioverse.aero/glossary/easa/level) and type of [aircraft](https://avioverse.aero/glossary/easa/aircraft) or, if unknown, relative speed of the conflicting traffic, e.g. slow or fast.

(b) [Pressure-altitude](https://avioverse.aero/glossary/easa/pressure-altitude)-derived level information, even when unverified, should be used in the provision of collision hazard information because such information, particularly if available from an otherwise unknown aircraft (e.g. a [VFR flight](https://avioverse.aero/glossary/easa/vfr-flight)) and given to the pilot of a known aircraft, could facilitate the location of a collision hazard. If the level information has not been verified, the [accuracy](https://avioverse.aero/glossary/easa/accuracy) of the information should be considered uncertain and the pilot should be informed accordingly.

## GM1 SERA.7002(a)(1) Collision hazard information when ATS based on surveillance are provided

INFORMATION REGARDING TRAFFIC ON CONFLICTING PATH OUTSIDE [CONTROLLED AIRSPACE](https://avioverse.aero/glossary/easa/controlled-airspace)

When an identified [IFR flight](https://avioverse.aero/glossary/easa/ifr-flight) operating outside controlled airspace is observed to be on a conflicting path with another [aircraft](https://avioverse.aero/glossary/easa/aircraft), the pilot should, as far as practicable:

(a) be informed as to the need for collision avoidance action to be initiated, and if so requested by the pilot or if, in the opinion of the [air traffic](https://avioverse.aero/glossary/easa/air-traffic) controller, the FIS officer or the AFIS officer, the situation warrants, a course of avoiding action should be suggested; and

(b) be notified when the conflict no longer exists.

GM Guidance material

## GM2 SERA.7002(a)(1) Collision hazard information when ATS based on surveillance are provided

The information presented on a situation display may be used to provide identified [aircraft](https://avioverse.aero/glossary/easa/aircraft) with information regarding any aircraft observed to be on a conflicting path with the identified aircraft, and suggestions or advice regarding avoiding action.

GM Guidance material

## GM3 SERA.7002(a)(1) Collision hazard information when ATS based on surveillance are provided

The provision of collision hazard information does not absolve pilots of [VFR](https://avioverse.aero/glossary/easa/vfr) flights from their responsibilities for avoiding terrain/obstacles and for maintaining [visual meteorological conditions](https://avioverse.aero/glossary/easa/visual-meteorological-conditions).

GM Guidance material

## GM4 SERA.7002(a)(1) Collision hazard information when ATS based on surveillance are provided

Collision hazard information should be provided where practicable. This should be done taking account of the priorities related to various tasks, such as provision of separation in accordance with the airspace classification, as well as equipment and workload limitations.
