Narrative:

Air carrier X on clt approach frequency. High traffic density; was switched to final approach controller. Controller immediately called for left turn 90 degree off inbound. Saw air carrier Y straight ahead given a turn 180 degree to ours. Judgement: overloaded controllers and 1 fast talking final controller that was at times difficult to understand.

Title: ACR X HAS LTSS FROM ACR Y. SYS ERROR.

Narrative: ACR X ON CLT APCH FREQ. HIGH TFC DENSITY; WAS SWITCHED TO FINAL APCH CTLR. CTLR IMMEDIATELY CALLED FOR L TURN 90 DEG OFF INBOUND. SAW ACR Y STRAIGHT AHEAD GIVEN A TURN 180 DEG TO OURS. JUDGEMENT: OVERLOADED CTLRS AND 1 FAST TALKING FINAL CTLR THAT WAS AT TIMES DIFFICULT TO UNDERSTAND.
