SECTION 7 AIR TRAFFIC SERVICES

Reference Description
SERA.7001 General — Objectives of the air traffic services
The objectives of the air traffic services shall be to:
(a) prevent collisions between aircraft;
(b) prevent collisions between aircraft on the manoeuvring area and obstructions on that area;
(c) expedite and maintain an orderly flow of air traffic;
(d) provide advice and information useful for the safe and efficient conduct of flights;
(e) notify appropriate organisations regarding aircraft in need of search and rescue aid, and
assist such organisations as required.
SERA.7001 GM1 General — Objectives of the air traffic services
GENERAL
These provisions are general statements which represent high-level safety objectives to be met when
providing ATS and which are the basis of all the provisions of this Part.
SERA.7002 Collision hazard information when ATS based on surveillance are provided
(a) When an identified controlled flight is observed to be on a conflicting path with an unknown
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.
SERA.7002(a)(1) AMC1 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 and type of aircraft or, if unknown, relative speed of the conflicting traffic, e.g.
slow or fast.
(b) 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) 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 of the information should be considered uncertain and the pilot
should be informed accordingly.
SERA.7002(a)(1) GM1 Collision hazard information when ATS based on surveillance are provided
INFORMATION REGARDING TRAFFIC ON CONFLICTING PATH OUTSIDE CONTROLLED
AIRSPACE
When an identified IFR flight operating outside controlled airspace is observed to be on a conflicting
path with another aircraft, the pilot should be:
(a) informed of the traffic, and if so requested by the pilot or if, in the opinion of the controller,
the situation warrants, a course of avoiding action should be suggested; and
(b) notified when the conflict no longer exists.

Centrik Regulations Team note: This item was due to be amended by EDD 2020/007/R however, the
applicability date for the changes fell after the EU exit date. Therefore, the amendments did not enter
UK Law and were not applied to this item.
SERA.7002(a)(1) GM1 to (a)(1) of Collision hazard information when ATS based on surveillance are provided
AMC1 In cases where using the terms of the 12-hour clock is not practicable, like when the aircraft is turning,
the direction of the unknown aircraft may be given by compass points, e.g. northwest, south, etc.;
SERA.7002(a)(1) GM1 to (a)(4) of Collision hazard information when ATS based on surveillance are provided
AMC1 The level may be described either as a flight level, altitude or height, or as a relative vertical distance
from the aircraft provided with traffic information (e.g. 1 000 ft above or 1 000 ft below).
SERA.7002(a)(1) GM2 Collision hazard information when ATS based on surveillance are provided
The information presented on a situation display may be used to provide identified aircraft with
information regarding any aircraft observed to be on a conflicting path with the identified aircraft, and
suggestions or advice regarding avoiding action.
SERA.7002(a)(1) GM3 Collision hazard information when ATS based on surveillance are provided
The provision of collision hazard information does not absolve pilots of VFR flights from their
responsibilities for avoiding terrain/obstacles and for maintaining visual meteorological conditions.
SERA.7002(a)(1) GM4 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.
