APCH CTLR COMPLAINT ABOUT FACILITY MGMNT RUNNING (TTG) TRAINING PROBS DURING MODERATE TO HVY TFC PERIODS. RPTR SAYS THIS SLOWS THE ARTS II SYS DOWN TOO MUCH AND IS A SAFETY HAZARD.

Narrative

CRP ATCT IS A LEVEL IV FACILITY WITH ARTS IIA EQUIP. WE ARE UNIQUE IN THAT WE HAVE 2 SEPARATE RADAR SYS WITHIN OUR FACILITY. WE HAVE AN ASR-8 FOR APCH CTL SVCS FOR THE CORPUS CHRISTI AREA; AND AN ASR-9 FOR APCH CTL SVCS FOR THE VALLEY AREA (BROWNSVILLE; HARLINGEN; AND MCALLEN). THE EQUIP WE HAVE WAS DESIGNED FOR A SLOW TO MODERATE LEVEL III FACILITY. WE ARE NOW THE BUSIEST LEVEL IV FACILITY IN THE SW REGION (SEP/96 DENSITY FACTORS). BECAUSE OF THE INCREASED WORKLOAD ON OUR EQUIP; MGMNT HAS BEGUN SCHEDULING INITIAL RADAR TRAINING (TTG'S) ON MID- SHIFTS. THEIR REASONING IS THAT OUR ARTS IIA SYS CONSISTENTLY OPERATES AT A NEAR CAPACITY LEVEL AND THE INCREASED WORKLOAD OF THE TTG'S WOULD CAUSE OUR ARTS TO FAIL. THIS BEING TRUE; THEN CRP IS WORKING AT SYS CAPACITY ON A DAILY BASIS ON THE VERGE OF OVERLOADING THE SYS CAUSING A MAJOR OUTAGE AND SAFETY CONCERN. ON OCT/THU/96; MGMNT TRIED TO RUN A SLOW (50 PERCENT) TTG PROB. THEY TRIED TO LOAD THE PROB AT XA30 AM; BUT WERE UNABLE TO GET THE TTG RUNNING. IF AT XA30 AM WE ARE ALREADY WORKING AT MAX SYS CAPACITY; WITH ONLY MODERATE TFC LEVELS; THE POTENTIAL FOR SYS FAILURE DURING HVY TFC PERIODS IS VERY REALISTIC. TO CONTINUE TO OPERATE A SYS THAT KNOWINGLY IS AT MAX CAPACITY WITHOUT ANY MEANS OF IMPROVEMENT OR RELIEF IS A SERIOUS SAFETY CONCERN.
