RPTR STATES THAT WHILE TRYING TO PERSONALIZE HIS DSR SCOPE; ACFT X AND Y WERE DSNDED. RPTR BELIEVED THAT ACFT Y WOULD NOT OVERTAKE ACFT X ON THE DSCNT. SEPARATION WAS LOST; RESULTING IN AN OPERROR.

Narrative

I HAD JUST TAKEN A POS RELIEF BRIEFING FROM THE PREVIOUS CTLR. ZOB IS WORKING WITH THE DSR SYS NOW. WITH THIS NEW SYS; EACH CTLR CAN SET UP THE SCOPE TO HIS/HER LIKING; IE; BACKGROUND COLOR; MAP BRIGHTNESS; TARGET BRIGHTNESS; ETC. SO IT TAKES SLIGHTLY LONGER TO SET UP THE SCOPE THAN IT DID WITH THE OLD M1 SYS. I WAS WORKING THE POS WITHOUT A RADAR ASSOCIATE BECAUSE TFC WAS SLOW. I WAS MOVING THE KEYBOARD; THE CURSOR BALL; AND THE DISPLAY KEYPAD; AND THE D-SIDE KEYBOARD TO WHERE I COULD USE THEM BEST; PLUS SETTING UP THE SCOPE; AND WORKING THE 3 ACFT I HAD. THE FIRST FEW MINS ON POS ARE USUALLY BUSY WITH SETTING UP THE EQUIP; AND IT IS DISTRACTING. I DSNDED THE FIRST ACFT TO 11000 FT AND I WAS STEPPING DOWN THE SECOND OVER THE FIRST. THE FIRST ACFT WAS AT 13900 FT WHEN I ASKED HIS RATE OF DSCNT. HE SAID 2000 FPM. THE SECOND WAS AT 16000 FT. AT #1'S RATE OF DSCNT; I FIGURED #2 COULDN'T CATCH HIM; SO I GAVE HIM A 12000 FT XING CLRNC. HE DUMPED IT MUCH FASTER THAN I EXPECTED. I COULD HAVE PROVIDED MORE POSITIVE CTL BY GIVING THE FIRST ACFT A HARD XING RESTR. BUT WHEN I FIRST DSNDED HIM; I THOUGHT THAT I WOULDN'T NEED IT. THE DSR COULD BE ENHANCED TO HELP WITH SET UP. THERE IS A PATCH AVAILABLE TO ALLOW US TO SIGN ON AND THE SCOPE WOULD AUTOMATICALLY CONFIGURE TO EACH CTLRS PREFERENCES. ZOB DOESN'T HAVE IT ON-LINE YET. THE SOONER THEY GET IT ON-LINE THE EASIER IT WOULD BE FOR ALL OF US.
