AN ACR MLG ALLOWED TRACON DEP CTLR TO PUT THE ACFT INTO THE EDGE OF HVY WX.

Narrative

WE TOOK OFF ON RWY 36 AT DCA; FLYING THE NOISE ABATEMENT DEP UP THE POTOMAC RIVER. WE LEVELED AT 5000 FT AND BEGAN TO WATCH A TSTM CELL ON OUR RADAR. IT RANGED FROM ABOUT 11 TO 2 O'CLOCK AND WAS ABOUT 15 MI AHEAD. DULLES DEP TOLD US TO TURN R TO 360 DEGS; WHICH LOOKED AS THOUGH IT WOULD 'NICK' THE R EDGE OF THE STORM; SO I TOLD THEM THE TURN LOOKED BAD. ONLY A 20-30 DEG TURN TO THE L WOULD HAVE KEPT US IN THE CLR; AND I WAS ABOUT TO MENTION THAT TO ATC WHEN THE CTLR SAID TO TURN R AGAIN; AND THE FO WAS SIMULTANEOUSLY SAYING 'YES IT WILL WORK IF WE DO IT IMMEDIATELY.' SO HE STARTED TO TURN AND I REPLIED TO ATC THAT WE WERE TURNING. AS WE COMPLETED THE TURN; WE COULD SEE IT WAS A MISTAKE; AS THE STORM WAS BUILDING RAPIDLY TO THE R. WE TOLD ATC WE WOULD NEED MORE DEV TO THE R AND HE BEGAN TO GET VERY NERVOUS; SAID WE COULDN'T GO TOO MUCH FURTHER TO THE R. HE HAD TAKEN US INTO A BLIND ALLEY. WE MANAGED TO PICK A RTE THAT WAS ONLY LIGHT TURB; BUT I WAS VERY UPSET AT BOTH MYSELF AND THE CTLR AFTERWARDS -- MYSELF BECAUSE I DIDN'T FOLLOW MY INSTINCTS INITIALLY AND REFUSE THE VECTOR IN FAVOR OF AN OBVIOUSLY BETTER DEV TO THE L; AND THE CTLR FOR PUTTING US IN THE CORNER THAT HE DID. I WAS ALSO UPSET FOR ALLOWING MYSELF TO BE 'LED' BY THE COPLT. I AM GOING TO SAY SOMETHING THAT'S 'POLITICALLY INCORRECT' HERE: COCKPIT RESOURCE MGMNT CAN GO TOO FAR! WHEN THE CHIPS ARE DOWN AND TIME IS SHORT; I'M GOING TO TRUST MY INSTINCTS THAT COME FROM 25 YRS OF AIRLINE FLYING AND NOT LET MYSELF BE 'LED' BY A GREEN CTLR AND A COPLT WITH A THIRD OF MY EXPERIENCE. COCKPIT RESOURCE MGMNT IS FINE IF YOU HAVE THE LUXURY OF TIME.
