For a Traffic Service in respect to deconfliction:
Whether traffic information has been passed or not, a pilot is expected to discharge
his collision avoidance responsibility without assistance from the controller. If after
receiving traffic information, a pilot requires deconfliction advice, an upgrade to
Deconfliction Service shall be requested. The controller shall make all reasonable
endeavours to accommodate this request as soon as practicable and provide
deconfliction advice at the earliest opportunity.
When providing headings/levels for the purpose of positioning and/or
sequencing or as navigational assistance, the controller should take into
account traffic in the immediate vicinity, so that a risk of collision is not
knowingly introduced by the instructions passed. However, the controller is not
required to achieve defined deconfliction minima.

How would you do that if you are IMC?
