B747 CREW DEPARTED WITH LESS THAN CLRED FUEL. ON DEP THEY HAD TRACK DEV.

Narrative

SCHEDULED FOR A FERRY FLT FROM SFO TO MIA. BASIC CREW -- CAPT; FO; FE. OUR FLT PLAN INDICATED 7000 KGS BALLAST FUEL ON THE FIRST PAGE. I COORDINATED WITH OUR DISPATCHER TO ADD 3000 KGS FOR CONTINGENCY. HOWEVER; OUR COMPANY ONLY LISTS BALLAST FUEL AT THE VERY START OF THE FLT PLAN UNDER 'TOTAL FUEL' AND DOES NOT INCLUDE IT IN THE 'BLOCKS FUEL;' 'TAKE OFF FUEL;' 'MINIMUM REQUIRED' OR ANYWHERE ELSE. AS A RESULT; I ADDED 3000 KGS TO OUR BLOCK FUEL; NOT TO THE TOTAL FUEL. THIS WAS DISCOVERED AT OUR FIRST FUEL PLOT. I INITIATED LONG RANGE CRUISE PROFILE; HAD OUR FE OPERATE WITH ONLY 1 ACFT PACK AND CLBED; WHEN ALLOWED BY ATC; TO FL410. WE LANDED IN MIA. BLOCK-IN FUEL WS 19600 KGS; WHICH EVEN WITH THE 7000 KGS BALLAST FUEL WAS OK. THE POINT IS; I RELEASED BRAKES WITH LESS THAN REQUIRED FUEL. NONE OF THE CREW WERE FERRIED WITH BALLAST FUEL ENOUGH TIMES TO BE FAMILIAR WITH OUR COMPANY'S METHOD OF TRACKING THE BALLAST. ALSO; ON DEP (DUMB6.LIN); THE #2 INS FAILED AS WE WERE CLRED DIRECT TO ALTAM. BAY DEP ASKED IF WE WERE TURNING N. THE FO WAS FLYING THE DEP AND I WAS RECONFIGURING OUR NAV SYS FOR A VOR/DME DEP WHEN BAY ASKED IF WE WERE TURNING. I RESPONDED THAT WE HAD A NAV FAILURE. ONCE RE-ESTABLISHED ON DEP; BAY CONFIRMED OUR NAV WAS OK AND SENT US TO OAKLAND. WE COMPLIED WITH OUR FLT HANDBOOK AND CONFIRMED STATUS WITH OUR MAINT; VIA PHONE PATCH.
