ManOps (Canadian version of MATS) states thou shall pass traffic information to aircraft that are going to be separated by the minimum standard, even if they are in the cruise.
Jerricho,
Just confirm that if you only require a 500ft standard, which you have in place, you still have to pass traffic, even though the aircraft are separated and are going to remain so??
If that is the case where I am I wouldn't stop talking!!!
