Narrative:

I was vectoring MTR X and MTR Y for multiple approachs at kelly AFB. Both aircraft were at 3000'. MTR X was downwind heading 330 degrees and MTR Y was heading 290 degrees. Standard missed approach for multiple approachs at kelly. I accepted a handoff on an mlt inbound for landing and left MTR Y heading 290 degrees to adjust the sequence to allow mlt to land ahead of MTR Y. I turned tail 16 to 340 degree heading to downwind and turned MTR X, then mlt to final and switched them to kelly tower. MTR Y did not turn as quickly as the average MTR instrument pilot and was wider than I anticipated. I then turned MTR Y to 100 degree heading for right base at kelly, and he responded, 'we have an obstruction in sight an would like to continue this heading for 2 mi to go around it.' I approved the maneuver, since there was no other traffic involved. I did not believe MTR Y was within 3 mi of the antenna at the time and was simply requesting to go around the obstruction on sight-seeing tour. After MTR Y returned to randolph AFB, he advised sof that he had been vectored in close proximity to an obstruction in the vicinity of medina lake. The supervisor at the TRACON then received a call from randolph sof, requesting he investigate this. The supervisor had me relieved and asked me what had occurred. At that time I relayed the above sequence of events. The MVA chart is not depicted on our normal working maps, an din our discussion we checked the MVA chart and I then realized that I had vectored the aircraft below the MVA in the vicinity of medina lake. It had been some time since our last change to the MVA chart and I was not recalling it correctly. I believe the MVA chart should be included on normal operational video maps in some manner.

Title: APCH CTLR VECTORED AN MTR TOO CLOSE TO AN OBSTRUCTION. MIL PLT COMPLAINT.

Narrative: I WAS VECTORING MTR X AND MTR Y FOR MULTIPLE APCHS AT KELLY AFB. BOTH ACFT WERE AT 3000'. MTR X WAS DOWNWIND HDG 330 DEGS AND MTR Y WAS HDG 290 DEGS. STANDARD MISSED APCH FOR MULTIPLE APCHS AT KELLY. I ACCEPTED A HANDOFF ON AN MLT INBND FOR LNDG AND LEFT MTR Y HDG 290 DEGS TO ADJUST THE SEQUENCE TO ALLOW MLT TO LAND AHEAD OF MTR Y. I TURNED TAIL 16 TO 340 DEG HDG TO DOWNWIND AND TURNED MTR X, THEN MLT TO FINAL AND SWITCHED THEM TO KELLY TWR. MTR Y DID NOT TURN AS QUICKLY AS THE AVERAGE MTR INSTR PLT AND WAS WIDER THAN I ANTICIPATED. I THEN TURNED MTR Y TO 100 DEG HDG FOR RIGHT BASE AT KELLY, AND HE RESPONDED, 'WE HAVE AN OBSTRUCTION IN SIGHT AN WOULD LIKE TO CONTINUE THIS HDG FOR 2 MI TO GO AROUND IT.' I APPROVED THE MANEUVER, SINCE THERE WAS NO OTHER TFC INVOLVED. I DID NOT BELIEVE MTR Y WAS WITHIN 3 MI OF THE ANTENNA AT THE TIME AND WAS SIMPLY REQUESTING TO GO AROUND THE OBSTRUCTION ON SIGHT-SEEING TOUR. AFTER MTR Y RETURNED TO RANDOLPH AFB, HE ADVISED SOF THAT HE HAD BEEN VECTORED IN CLOSE PROX TO AN OBSTRUCTION IN THE VICINITY OF MEDINA LAKE. THE SUPVR AT THE TRACON THEN RECEIVED A CALL FROM RANDOLPH SOF, REQUESTING HE INVESTIGATE THIS. THE SUPVR HAD ME RELIEVED AND ASKED ME WHAT HAD OCCURRED. AT THAT TIME I RELAYED THE ABOVE SEQUENCE OF EVENTS. THE MVA CHART IS NOT DEPICTED ON OUR NORMAL WORKING MAPS, AN DIN OUR DISCUSSION WE CHKED THE MVA CHART AND I THEN REALIZED THAT I HAD VECTORED THE ACFT BELOW THE MVA IN THE VICINITY OF MEDINA LAKE. IT HAD BEEN SOME TIME SINCE OUR LAST CHANGE TO THE MVA CHART AND I WAS NOT RECALLING IT CORRECTLY. I BELIEVE THE MVA CHART SHOULD BE INCLUDED ON NORMAL OPERATIONAL VIDEO MAPS IN SOME MANNER.
