Narrative:
Targets on a 'Y' tag (vny tower identify) cannot be taken off the woodland radar (at bur-sct). As a result, there is mass clutter at times around vny that makes it impossible to issue inbound acrs to bur accurate traffic. Callback conversation with reporter revealed the following information: 4 calls to reporter without response. Analyst called socal TRACON (sct) specialist to validate reporter statement. Specialist advised sct transitioned to ARTS IIIE capability sep/98. The specialist confirmed that the new system had a couple functions that needed changing. The condition the reporter states that when the quicklook function was utilized by a controller drawing up the radar displayed tracked targets of another sector, the full data block remained. This is not a desirable condition with this function. The controller wants to look at the other controller's data blocks in a compressed visual display, the controller's sector tag with mode C readout only, not the complete 2 lines of the full data block. This condition is most noticeable in the vny/bur control area jurisdictions. An emergency national product review (npr) was submitted by sct management 12/98. The original sct ARTS III program request that had this amended function was inadvertently dropped out of the national program. A facility ucr was also submitted addressing this problem. The specialist advised that he expected resolution by late spring or early summer.

Title: TRACON APCH CTLR CONCERNED WITH RADAR ARTS TAG CLUTTER, NOT BEING ABLE TO ISSUE TIMELY TA'S TO ACFT CONDUCTING AN APCH TO BUR ARPT, DUE TO ARTS TAG CLUTTER AS ACFT PASSES OVER VNY ARPT.
Narrative: TARGETS ON A 'Y' TAG (VNY TWR IDENT) CANNOT BE TAKEN OFF THE WOODLAND RADAR (AT BUR-SCT). AS A RESULT, THERE IS MASS CLUTTER AT TIMES AROUND VNY THAT MAKES IT IMPOSSIBLE TO ISSUE INBOUND ACRS TO BUR ACCURATE TFC. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: 4 CALLS TO RPTR WITHOUT RESPONSE. ANALYST CALLED SOCAL TRACON (SCT) SPECIALIST TO VALIDATE RPTR STATEMENT. SPECIALIST ADVISED SCT TRANSITIONED TO ARTS IIIE CAPABILITY SEP/98. THE SPECIALIST CONFIRMED THAT THE NEW SYS HAD A COUPLE FUNCTIONS THAT NEEDED CHANGING. THE CONDITION THE RPTR STATES THAT WHEN THE QUICKLOOK FUNCTION WAS UTILIZED BY A CTLR DRAWING UP THE RADAR DISPLAYED TRACKED TARGETS OF ANOTHER SECTOR, THE FULL DATA BLOCK REMAINED. THIS IS NOT A DESIRABLE CONDITION WITH THIS FUNCTION. THE CTLR WANTS TO LOOK AT THE OTHER CTLR'S DATA BLOCKS IN A COMPRESSED VISUAL DISPLAY, THE CTLR'S SECTOR TAG WITH MODE C READOUT ONLY, NOT THE COMPLETE 2 LINES OF THE FULL DATA BLOCK. THIS CONDITION IS MOST NOTICEABLE IN THE VNY/BUR CTL AREA JURISDICTIONS. AN EMER NATIONAL PRODUCT REVIEW (NPR) WAS SUBMITTED BY SCT MGMNT 12/98. THE ORIGINAL SCT ARTS III PROGRAM REQUEST THAT HAD THIS AMENDED FUNCTION WAS INADVERTENTLY DROPPED OUT OF THE NATIONAL PROGRAM. A FACILITY UCR WAS ALSO SUBMITTED ADDRESSING THIS PROB. THE SPECIALIST ADVISED THAT HE EXPECTED RESOLUTION BY LATE SPRING OR EARLY SUMMER.
