Narrative

ACR X ON DSCNT/APCH UNDER RADAR VECTORS BY DEN APCH. WE WERE GIVEN A TURN TO 020 DEGS BECAUSE OF TFC. WE WERE UNABLE TO COMPLY DUE TO SEVERE WX (TSTM) ON THAT HDG. AT THE SAME TIME; WE GOT A TCASII RA TO DSND. WE DID; AND DSNDED TO 10500 FT (CONFLICT WAS RESOLVED). THE CTLR (AT SAME TIME) GAVE ACR Y AN IMMEDIATE TURN. WE RETURNED TO 11000 FT. CTLR WAS VERY UPSET THAT WE DID NOT COMPLY WITH HIS VECTOR. ANY PROFESSIONAL PLT KNOWS THAT SEVERE WX AVOIDANCE IS MORE IMPORTANT THAN A SANITIZED APCH. (SO IS AVOIDING TFC.) CTLRS SHOULD REALIZE THAT IT IS NOT ALWAYS POSSIBLE TO EXACTLY COMPLY WITH THEIR INSTRUCTIONS AND SHOULD HAVE AN ALTERNATE PLAN (I THINK MOST DO). THIS CTLR SEEMED NOT TO EVER UNDERSTAND OUR NEEDS AND OUR REACTION. SUPPLEMENTAL INFORMATION FROM ACN 244135: DEN APCH ISSUED ACR X A 020 DEG HDG. I RESPONDED UNABLE ACCOUNT TSTM ACTIVITY. I ADVISED WE COULD FLY A 355 DEG HDG AND DEN DID NOT RESPOND IMMEDIATELY; BUT ISSUED ACR Y A TIGHT R TURN. SHORTLY THEREAFTER; TCASII ISSUED AN RA 'DSND; DSND.' WE DSNDED TO 10500 FT UNTIL CLR OF CONFLICT AND RETURNED TO 11000 FT. TALKED BY PHONE WITH DEN TRACON ABOUT LOSS OF SEPARATION AND MY RELUCTANCE TO FLY INTO TSTMS.
