NON ACKNOWLEDGEMENT OF ATC INSTRUCTION CLRNC BY PIC ON DEP PROC CREATES A TECHNICAL HDG TRACK DEV.

Narrative

I WAS CAPT ON THIS FLT AND WAS CLRED FOR TKOF RWY 29R TO MAINTAIN RWY HDG. THE COPLT WAS FLYING WHEN AT ABOUT 1600 FT MSL THE TWR TRIED TO GIVE ME A CLRNC. AT THIS CRITICAL PHASE OF THE FLT I COULD NOT SAFELY ACCEPT A CLRNC LET ALONE READ IT BACK. TO ATTEMPT TO DO SO WOULD HAVE BROKEN MY CONCENTRATION OF MONITORING ACFT PERFORMANCE; COPLT PERFORMANCE; AND VISUAL TFC. THE CTLR CALLED AGAIN A FEW SECONDS LATER AS WE WERE STARTING TO RETRACT THE FLAPS. SINCE I STILL COULD NOT ACCEPT A CLRNC I BROKE MY CONCENTRATION LONG ENOUGH TO TELL THE CTLR TO STAND BY. I WOULD RATHER HAVE NOT TRIED TO TALK TO THE CTLR AT THIS TIME BUT I REALIZED THAT HE WOULD HAVE CONTINUED TO CALL; FURTHER DETRACTING FROM MY SAFE OP OF MY ACFT. A FEW SECONDS LATER AFTER THE FLAPS WERE UP AND WE WERE STABILIZED IN A CLB; I CALLED THE TWR AND TOLD THEM TO GO AHEAD WITH THE CLRNC. WE WERE CLRED TO TURN TO 360 DEG AND CONTACT DEP CTL. I READ BACK THE CLRNC AS REQUIRED AND COMPLIED. LATER IN THE CLB; IT WAS REQUESTED THAT I CONTACT A PHONE NUMBER WHEN I GOT ON THE GND. I RESPONDED THAT I WOULD DO SO WHEN I RETURNED FROM YWC. I MADE THIS TELEPHONE CALL AT ABOUT XX40 LCL SEP/MON/91. I WAS TOLD THAT THINGS WERE DONE DIFFERENTLY AT MSP AND THAT I MESSED UP THE WORKS BY NOT ACCEPTING THE CLRNC WHEN IT WAS ISSUED REGARDLESS OF THE PHASE OF FLT OR THE WORKLOAD I WAS UNDER. I SUGGESTED THAT THIS COULD BE AVOIDED IN THE FUTURE IF THEY WOULD BUT GIVE US ANY HDG REQUIREMENTS BEFORE TKOF. THIS WOULD ALLOW ALL MY CREW TO UNDERSTAND THE CLRNC AND WE COULD CONCENTRATE ON FLYING THE ACFT SAFELY. HE TOLD ME THAT WAS NOT POSSIBLE BECAUSE OF NOISE RESTRICTIONS. I THEN SUGGESTED THAT A SID BE DEVELOPED BUT WAS TOLD THAT THIS WAS ALSO IMPOSSIBLE. I DO NOT UNDERSTAND WHY THIS IS IMPOSSIBLE AT MSP OR ANY OTHER UNITED STATES ARPT SINCE IT IS DONE ALL OVER CANADA AND EVEN AT VERY BUSY ARPTS LIKE TORONTO THE TWR CTLR DOES NOT FIND IT NECESSARY TO TALK TO US AFTER WE HAVE BEEN ISSUED TKOF CLRNC. I AM SORRY TO HAVE CAUSED A PROBLEM BUT I WOULD BE REMISS IN MY DUTIES AS CAPT IF I WERE TO ALLOW A DETERIORATION OF SAFETY MARGINS JUST TO MAKE WORK EASIER FOR THE CTLR. THIS POLICY THAT ALLOWS CTLRS TO BADGER US WITH CLRNCS DURING CRITICAL PHASES OF FLT IS UNNECESSARY AND TERRIBLY UNSAFE AND SHOULD BE STOPPED IMMEDIATELY.
