Narrative:

2 ARTS iie problems: 1) when accepting a handoff of a nat (non ARTS track) target via the handoff + ok function, the alpha numeric tag immediately drop off the radar screen and into the coast/suspend list. These tags should only drop when they enter a designated 'drop zone' or when terminated by the controller. In all other cases they should remain on the screen in a 'frozen' state. 2) departure flight plans from evv airspace that are bound for ARTCC airspace cannot be handed off automatically, via ARTS handoff function, if the flight plan has been amended in any way. This problem became an issue once again after the installation of revision dated may/xa/01 which replaced revision dated aug/xa/00. Callback conversation with reporter revealed the following information: reporter states that evv was changed to ARTS iie approximately 2.5 yrs ago. When mode south was added to their ASR-7, handoff problems decreased. 2 other approach controls adjoin evv, but most of the arrival handoff problems are from sdf approach control, which has an ASR-9 radar. The controller believes all automation xfers, including approach-to-approach are routed through ZID. Aircraft are routed direct pxv VORTAC landing evv, or direct their destination airport within evv airspace. The reporter believes that handoff problems are not altitude sensitive. The reporter states that correct communication is conducted with each handoff when a 'CST' track is observed. The problem is that after 3 sweeps, the automation is supposed to freeze the ARTS tag until the controller conducts further functions to verify track position. But the tag immediately drops from the radar into the 'CST/suspend' list. The controller is aware that a ucr has been filed with the facility concerning these issues.

Title: EVV APCH CTLR CONCERNED WITH FACILITY ARTS IIE SOFTWARE PROBS DEALING WITH ARR ACFT ARTS TAGS THAT DO NOT 'FREEZE' AFTER CHANGING FROM A 'CST' STATUS, AND THE INABILITY TO EFFECT AN AUTOMATED DEP HDOF TO ZID IF THE ORIGINAL FLT PLAN HAS BEEN AMENDED.

Narrative: 2 ARTS IIE PROBS: 1) WHEN ACCEPTING A HDOF OF A NAT (NON ARTS TRACK) TARGET VIA THE HDOF + OK FUNCTION, THE ALPHA NUMERIC TAG IMMEDIATELY DROP OFF THE RADAR SCREEN AND INTO THE COAST/SUSPEND LIST. THESE TAGS SHOULD ONLY DROP WHEN THEY ENTER A DESIGNATED 'DROP ZONE' OR WHEN TERMINATED BY THE CTLR. IN ALL OTHER CASES THEY SHOULD REMAIN ON THE SCREEN IN A 'FROZEN' STATE. 2) DEP FLT PLANS FROM EVV AIRSPACE THAT ARE BOUND FOR ARTCC AIRSPACE CANNOT BE HANDED OFF AUTOMATICALLY, VIA ARTS HDOF FUNCTION, IF THE FLT PLAN HAS BEEN AMENDED IN ANY WAY. THIS PROB BECAME AN ISSUE ONCE AGAIN AFTER THE INSTALLATION OF REVISION DATED MAY/XA/01 WHICH REPLACED REVISION DATED AUG/XA/00. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATES THAT EVV WAS CHANGED TO ARTS IIE APPROX 2.5 YRS AGO. WHEN MODE S WAS ADDED TO THEIR ASR-7, HDOF PROBS DECREASED. 2 OTHER APCH CTLS ADJOIN EVV, BUT MOST OF THE ARR HDOF PROBS ARE FROM SDF APCH CTL, WHICH HAS AN ASR-9 RADAR. THE CTLR BELIEVES ALL AUTOMATION XFERS, INCLUDING APCH-TO-APCH ARE ROUTED THROUGH ZID. ACFT ARE ROUTED DIRECT PXV VORTAC LNDG EVV, OR DIRECT THEIR DEST ARPT WITHIN EVV AIRSPACE. THE RPTR BELIEVES THAT HDOF PROBS ARE NOT ALT SENSITIVE. THE RPTR STATES THAT CORRECT COM IS CONDUCTED WITH EACH HDOF WHEN A 'CST' TRACK IS OBSERVED. THE PROB IS THAT AFTER 3 SWEEPS, THE AUTOMATION IS SUPPOSED TO FREEZE THE ARTS TAG UNTIL THE CTLR CONDUCTS FURTHER FUNCTIONS TO VERIFY TRACK POS. BUT THE TAG IMMEDIATELY DROPS FROM THE RADAR INTO THE 'CST/SUSPEND' LIST. THE CTLR IS AWARE THAT A UCR HAS BEEN FILED WITH THE FACILITY CONCERNING THESE ISSUES.
