Narrative:

Scheduled for a ferry flight from sfo to mia. Basic crew -- captain, first officer, flight engineer. Our flight 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 flight 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 flight engineer operate with only 1 aircraft pack and climbed, 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 departure (DUMB6.lin), the #2 INS failed as we were cleared direct to altam. Bay departure asked if we were turning north. The first officer was flying the departure and I was reconfiguring our navigation system for a VOR/DME departure when bay asked if we were turning. I responded that we had a navigation failure. Once re-established on departure, bay confirmed our navigation was ok and sent us to oakland. We complied with our flight handbook and confirmed status with our maintenance, via phone patch.

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.
