ED Decision 2020/008/R

INFORMATION REGARDING TRAFFIC ON A 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.

(c)      If the level information has not been verified, the accuracy of the information should be considered uncertain and the pilot should be informed accordingly.
