ALT XING RESTR -- DEV FROM CLRNC -- ACR FAILS TO MAKE A XING RESTR AND LATER FAILS TO FOLLOW THE ASSIGNED TAXI RTE.

Narrative

I HAD A BAD DAY -- I WAS ASSIGNED AN INTL TRIP; EVEN THOUGH I TOLD SCHEDULING I FELT I WAS GETTING SICK. ON RETURN LEG INTO BALTIMORE THE NEXT DAY; I AM WELL INTO A COMMON COLD AND NOT FEELING WELL; BESIDES BEING RATHER FATIGUED AFTER A 7.5 HR TRIP. ON DSCNT; WE WERE CLRED TO CROSS 10 (OR 15) DME N OF XXX VOR AT 5000 FT. BECAUSE THE ATIS WIND RPT INDICATED A LNDG WITH A STRONG QUARTERING TAILWIND; WE WAITED UNTIL 12000 FT TO BRIEF THE APCH WE WERE GOING TO REQUEST. AS IT TURNED OUT; THE WIND CHANGED; AND WE LANDED ON THE DESIGNATED RWY. I GAVE CTL OF THE ACFT TO THE CAPT; BRIEFED THE APCH; THEN RESUMED CTL OF THE ACFT. SHORTLY THEREAFTER; I REALIZED WE WERE NOT GOING TO MAKE THE XING RESTR AND ADVISED ATC. THEY REPLIED; 'I SEE THAT. EXPEDITE YOUR DSCNT; YOU HAVE TFC 1 O'CLOCK; 9 MI.' AFTER LNDG; I WAS TAXIING THE ACFT FROM THE R SEAT AND TURNED ONTO THE WRONG TXWY. GND CTL SCOLDED US AND TOLD US TO MAKE A TURN BACK TO OUR ASSIGNED TXWY. THE CAPT TOOK CTL; ADDED PWR TO MAKE THE TURN AND BLEW DOWN 2 TXWY SIGNS IN THE PROCESS; WHICH WERE THEN LAYING OUT ON THE TXWY. WE THEN TAXIED AROUND THE SIGNS AND TO OUR DESIGNATED GATE. AFTER BLOCKING IN; THE CAPT AND I WERE BOTH UPSET. I FELT I SHOULD NOT HAVE BEEN PRESSURED TO FLY WHEN I WAS SICK; AND HE WAS CONCERNED ABOUT THE DAMAGE HE HAD DONE TO THE ARPT SIGNS -- MY FAULT IN THE FIRST PLACE. I THINK INTL FLT REGS ARE TOO RELAXED -- NO DUTY TIME LIMIT!? JET LAG; COMBINED WITH UNUSUAL HRS; THE FATIGUE OF LONG FLYING LEGS; AND THE COMPLEXITY OF INTL/FOREIGN FLT OPS; MANDATES THE NECESSITY FOR AN INTL DUTY TIME LIMIT.
