FLC DEPARTED FOREIGN ARPT WITHOUT PROPER SID CHART.

Narrative

CAPT'S FIRST TRIP FROM AVIANO. MY SECOND TRIP FROM AVIANO. FE WAS ALSO UNFAMILIAR. CLRNC WAS ISSUED BY GND CTL JUST PRIOR TO REACHING ACTIVE DEP RWY. CLRNC TO THE ENRTE PHASE WAS VIA THE 'VINCENZA 6B DEP.' OUR RESOURCES INCLUDED THE COMMERCIAL CHARTS (2 APCH PROCS AND THE ARPT CHART). GOV FLIP CHARTS (SAME AS COMMERCIAL); GOV REVISIONS (NOTHING); AND GOV ARPT BOOK (LOTS OF VERBIAGE ON THE ARPT; BUT NO SID). AT ABOUT THE SAME TIME THAT WE EXHAUSTED OUR ONBOARD RESOURCES; I RECALLED THAT ON MY 1 PREVIOUS TRIP FROM THIS ARPT; THE CAPT HAD PULLED FROM HIS COLLECTION A PHOTOCOPY OF THE VIC 6B DEP -- THE SOURCE OF WHICH REMAINS A MYSTERY TO ME. I SHARED WHAT I COULD REMEMBER FROM THE DEP PROC WITH MY CAPT. HE HAD ME ADVISE THE CTLR THAT WE HAD FOUND THE DEP PROC. I WAS A BIT LEERY. HIS IDEA WORKED. THE CTLR ASKED IF WE HAD THE ISSUE SHOWING THE R TURN AT 600 FT; ETC; AS HE APPARENTLY READ TO US THE ENTIRE SID. I SCRIBBLED IT ALL DOWN; WE SET UP OUR NAV EQUIP; CALLED FOR TKOF CLRNC; AND DEPARTED. OUR MISTAKE HERE WAS OUR FAILURE TO BRIEF WHAT WE HAD JUST HEARD ('HAD TO MAKE THAT SLOT TIME'). AFTER TKOF AND THE FIRST 2 TURNS; THE CAPT ACQUIRED AND NAVED DIRECT TO VENEZIA; ABOUT 30 NM TO THE S. I THOUGHT I HAD HEARD 'DIRECT TO VINCENZA' AS PART OF THE SID. I FIGURED I MUST HAVE MISUNDERSTOOD. AFTER ABOUT 2 MINS AND 8-10 NM ON THE SBOUND COURSE; THE CTLR ADVISED US TO TURN IMMEDIATELY TOWARD; AND FLY TO VINCENZA; ABOUT 30 NM TO THE W OF THE ARPT. WE DID; AND PROCEEDED WITHOUT FURTHER INCIDENT. FLYING AROUND WITHOUT THE NECESSARY CHARTS ON BOARD IS NOT A GOOD IDEA; BUT THE TEMPTATION TO DO SO COULD BE REDUCED IF THE RELEVANT PROC WERE EITHER PUBLISHED APPROPRIATE OR ELSE ELIMINATED!
