Narrative:
Tul approach runs opposite direction VFR practice approachs at rvs when rvs is in a south flow. Tul is responsible for separation (radar) with rvs's automatically released IFR departures. The IFR cessna departed rvs and was head-on with the VFR on the practice approach. Neither aircraft responded to the 2 ATC facilities until they were approximately 3 mi apart (head-on). At that time, the rvs controller canceled the approach clearance of the VFR and instructed him to enter a downwind (saving an operational error). The event is one of many occurrences of this exact type at this exact location.

Narrative: TUL APCH RUNS OPPOSITE DIRECTION VFR PRACTICE APCHS AT RVS WHEN RVS IS IN A S FLOW. TUL IS RESPONSIBLE FOR SEPARATION (RADAR) WITH RVS'S AUTOMATICALLY RELEASED IFR DEPS. THE IFR CESSNA DEPARTED RVS AND WAS HEAD-ON WITH THE VFR ON THE PRACTICE APCH. NEITHER ACFT RESPONDED TO THE 2 ATC FACILITIES UNTIL THEY WERE APPROX 3 MI APART (HEAD-ON). AT THAT TIME, THE RVS CTLR CANCELED THE APCH CLRNC OF THE VFR AND INSTRUCTED HIM TO ENTER A DOWNWIND (SAVING AN OPERROR). THE EVENT IS ONE OF MANY OCCURRENCES OF THIS EXACT TYPE AT THIS EXACT LOCATION.
