CARGO ACFT HAS EQUIP PROB RESULTING IN HDG DEV.

Narrative

THIS PROB STARTED ON THE TURN TOWARDS CANARSI VOR. THE FO WAS FLYING THE ACFT. HE BEGAN AN IMMEDIATE TURN WITH EXCESSIVE BANK ANGLE FOR THE INDICATED AIRSPD. I REMINDED HIM TO WATCH HIS BANK ANGLE. THIS SEEMED TO MAKE HIM EVEN MORE DETERMINED. IN ADDITION TO THIS; DURING THE TURN THE INST COMPARATOR HDG LIGHT ILLUMINATED WITH A VARIATION IN THE COMPASSES. I WASN'T SURE WHICH OF THE COMPASSES WERE RIGHT. MY RMI NEEDLES WERE NOT POINTING IN THE SAME DIRECTION AS HIS. MINE WERE POINTING TO THE R ABOUT 25-30 DEGS AND HIS WERE POINTING STRAIGHT AHEAD. A QUICK CHK REVEALED THAT THE COMPASSES ON BOTH SIDES WERE NOW ON THE SAME HDG AS WE ROLLED OUT OF THE TURN AT SOMEWHERE AROUND 180 DEGS. THE FO NEXT CALLED FOR FLAP RETRACTION. AS WE WERE RETRACTING THE FLAPS I STATED 'WHERE ARE YOU GOING. TURN R TO THE VOR.' HE BECAME VERY ASSERTIVE THAT HE WAS GOING TO THE VOR AND POINTED TO HIS RMI. I CHKED THE VOR FREQS COMPARED TO THE DEP PLATE AND THEY WERE CORRECT. I THEN NOTICED THAT THE SWITCHES ON HIS RMI WERE IN THE ADF POS. I SAID; 'IF YOU'LL PUT YOUR RMI SWITCHES TO THE VOR POS; YOU WILL SEE WHERE IT IS.' AGAIN HE SAID 'I'M GOING TO THE VOR!' SIMULTANEOUSLY; THE DEP CTLR ASKS; 'ACR X WHAT DEP WERE YOU ASSIGNED?' THE FO HAS NOW STARTED A TURN TOWARD THE VOR. I WENT TO ANSWER THE XMISSION AND COVERED HIS NEXT QUERY. HE THEN CAME BACK AGAIN; I BELIEVE; AND SAID 'ACR X WHAT DEP WERE YOU ASSIGNED -- TURN R HDG 250 DEGS.' I ANSWERED BY APOLOGIZING FOR COVERING THE XMISSION AND STATED 'BREEZY POINT CLB; HDG 250.' THE CTLR'S NEXT RADIO CALL WAS A FREQ CHANGE. ON THE HUMAN PERFORMANCE SIDE I SEE 2 FACTORS. THE EVENING PRIOR TO THE FLT I WAS UNABLE TO GET ANY MEANINGFUL REST. WE HAD A VERY EARLY GET-UP FLOWN FROM SDF TO JFK BUT FOR AN HR AND A HALF. NOW; I'M STARTING TO GET TIRED; AND MY THOUGHT PROCESSES JUST SEEM SLOW. I VALUE THIS LESSON TO ME ON INACTION. I SHOULD HAVE BEEN MORE ACTIVE BY TAKING THE ACFT AND ASKED FOR A CORRECT DIRECTION HDG AS SOON AS I WAS UNCERTAIN AS TO WHICH COMPASS WAS RIGHT OR WRONG; EVEN THOUGH IT WAS MOMENTARY. THERE IS 1 FINAL THING I CAN THINK OF THAT MAY HAVE CONTRIBUTED TO THE FO'S AGGRESSIVENESS: OUT OF SDF; COMPANY HAD PROVIDED THE CREW WITH MEALS. THE FO HAD GOTTEN INTO HIS AND FOUND A TOOTHPICK IN HIS FRUIT. THINKING THAT IT MIGHT HAVE BEEN A USED TOOTHPICK; HE IMMEDIATELY GETS ON THE RADIO TO COMPANY AND DEMANDS ANOTHER MEAL. WE WERE GETTING VERY CLOSE TO DEP TIME WHEN SOMEONE FROM THE COMPANY ARRIVED AT THE ACFT TO CHK OUT THE PROB. I ASKED THE FO IF IT WOULD BE ALL RIGHT IF THE COMPANY DELIVERED HIM A MEAL AT JFK; AND IF THE OTHER PARTS OF HIS MEAL WERE OK. TO MAKE A LONG STORY SHORT; THE MEAL DIDN'T SHOW AT JFK AND HE IS ON THE RADIO AGAIN. I TOLD HIM HE WAS WELCOME TO MINE OR POSSIBLY TRY AGAIN IN ATL. HE DID SEEM UPSET THAT I WOULD NOT DELAY THE FLT FOR HIS MEAL UNLESS HE REFUELED TO GO WITHOUT IT.
