Here is the question:
Can i use visual seperation by calling the final controller, making a traffic call,have the final controller wait for his aircraft to report my aircraft in sight, then have the final controller tell his aircraft on GCA final to maintain visual sep, caution wake turbulance? I realy dont think you can. you are adjusting the aircrafts flight path with ever turn you give him on a PAR and if it is some monitiored instrument approach the aircraft cant deviate from the published proceedure to maintain visual. So then in that case do i need the approprite mileage behind the heavy? And if i do need mileage who is responsible, radar, or tower. And does that change if i have a certified radar display in the tower or not? Chew on that for a while, let me know what you guys come up with.

you seem to know all the rule pertaining to this. i will add this though. if a controller tells a pilot to maintain visual separation, it is up to the pilot to tell the controller if he can no longer do it. i would say this includes with wake turbulence.
one more thing is this
5-9-5. APPROACH SEPARATION
RESPONSIBILITY
a. The radar controller performing the approach
control function is responsible for separation of radar
arrivals unless visual separation is provided by the
tower, or a letter of agreement/facility directive
authorizes otherwise.
Radar final controllers ensure
that established separation is maintained between
aircraft under their control and other aircraft
established on the same final approach course.
so as long as you call the traffic. it is up to the final controller to make sure.
next up, i would ask why you would tell a pilot on final to maintain visual separation from an aircraft in the vfr pattern? do you do this every time you have vfr traffic and GCA traffic? or just when the vfr traffic is heavy? i've done lots of mixed gca/tower pattern but rarely did we deal with heavy a/c in our tower pattern.
