FMS FAILURE ON CL65 PUTS FLT CREW IN A DIFFICULT SITUATION BECAUSE THEY HAD NOT PREPARED ANY RAW DATA BACKUPS FOR THE FMS RTE; NOR DID THEY HAVE PAPER CHARTS READILY AVAILABLE TO PROVIDE NAV RESOURCE DATA.

Narrative

DEPARTING RWY 19 FROM DCA ON A VECTOR TO THE NE AND CLBING TO 10000 FT MSL I FOUND THE FMS HAD FAILED REMOVING MY FILED RTE AND ALL SITUATIONAL DATA FROM MY MFD; THE FAILURE OF MY FMS WAS TOTAL AND NOT RECOVERABLE. I BEGAN GETTING THE APPROPRIATE CHARTS OUT TO FIX MY POS RELATIVE TO V268 WHICH I HAD BEEN FILED ON. ATC CLRED ME DIRECT SWANN; I TOLD THEM I WAS NEGATIVE FMS AND ASKED FOR A HDG WHICH I WAS ASSIGNED. THEN POTOMAC DEP XFERRED ME TO ZDC. I CHKED IN WITH MY HDG AND 10000 FT ALSO STATING NEGATIVE FMS. WASHINGTON ASSIGNED ME DIRECT BROSS AND I AGAIN STATED THAT I WAS UNABLE DUE TO AN FMS FAILURE. THEY ASKED IF I COULD INTERCEPT V268 WHICH I ACCEPTED. ALMOST IMMEDIATELY ZDC XFERRED ME TO ANOTHER WASHINGTON SECTOR WITH A CLB TO FL190. I CHKED IN WITH MY CURRENT HDG INTERCEPT INSTRUCTIONS AND CLB CLRNC WITH A POS APPROX 25 NM NE OF DCA. AFTER SOME CONFUSION THE NEW ZDC CTLR DETERMINED I HAD THE WRONG FREQ AND RETURNED ME TO MY PREVIOUS CTLR. I CHKED BACK IN AND WAS GIVEN ANOTHER FREQ .05 DIFFERENT. ALL OF THIS OCCURRED IN A VERY SHORT PERIOD OF TIME; DISTRACTING ME FROM FINDING THE FREQ AND RADIAL FOR ENO AND V268. I HAD REQUESTED THE FREQ FROM ATC AND WAS NOT PROVIDED IT PRIOR TO THE CHANGE OVER TO THE WRONG FREQ. I CHKED ON WITH THE NEW FREQ WITH MY HDG STATING NEGATIVE FMS. BY THIS TIME I ASSUME I HAD FLOWN THROUGH V268 BECAUSE I WAS ASSIGNED A NEW HDG TO THE SE. SEVERAL MOMENTS LATER CTR ASKED IF I WAS CLBING TO FL190. I REPLIED THAT I WAS STARTING THE CLB. I ESTIMATE I WAS ABOUT 3-5 MINS LATE IN STARTING THE CLB TO FL190. I FINALLY LOCATED THE FREQ AND RADIAL FOR V268 ON THE LOW ALT CHARTS AND WAS THEN ASSIGNED DIRECT COYLE (CYN). I TUNED CYN AND FLEW MY COURSE DIRECT TO CYN USING VOR NAV FOR THE REMAINDER OF MY FILED RTE. DURING THIS EVENT I WAS THE PF WITH THE FO OPERATING THE RADIOS. HE WAS BEING INDIRECT WITH HIS REQUESTS WITH ATC SO I ASSUMED RADIO DUTIES AS WELL AS PF DUTIES WHILE TRYING TO LOCATE MYSELF ON THE AIRWAY. I SHOULD HAVE XFERRED CTL TO THE FO ALLOWING ME TO FOCUS ON OUR POS AND ATC MORE DIRECTLY. SINCE THIS EVENT I HAVE BEEN TUNING THE FIRST AIRWAY NAVAID IN MY STANDBY RADIO AND DIALING MY VOR COURSE NEEDLE TO THE APPROPRIATE HDG THEN REVERTING TO FMS CTL PRIOR TO EACH DEP.
