Howabout, I understand the answer is simple. Airservices claim they cannot offer “green in between” or “target resolution” because all of their radars use multi radar tracking.
That's why they have no procedures for this.
In the case of Williamtown,I am told that the terminal radar used for aircraft in close does not use multi radar tracking. Therefore, if the powers that be decided to follow the proven US civilian and military procedures of “green in between” and “target resolution” they would be able to operate aircraft more efficiently without needless holding.
Those are the facts!
