Shortly, I will have to fly a Baron from USA to Australia after I have
ferry tanks installed.

The route I plan to do is:

Oakland/San Francisco - Hawaii : 3850 Kilometers (2075nm)
Hawaii - Tarawa : 3860 Kilometers (2080nm)
Tarawa - Brisbane : 3840 Kilometers (2070nm)

I understand that I need to fly below 10,000 feet because of the
westerlies especially during the first 2 legs. I'm working on 13
hours flying time on each leg with a 2 hour reserve.

What do others think?? Especially other pilots who have flown this or
a similar route. Is what I plan OK or do you have any other
suggestions or hints you think I should need to know??
