Cloud Nine will be doing two hurricane relief flights from St. Croix this weekend. I'll be flying south on Friday, north (and back south again) on Saturday, then north and home Sunday. If we get too tired on Sunday (thinking especially if there are bad headwinds heading home) we'll just stop someplace for the night.
This flight has some long legs, so fuel planning and contingencies are important. The 414 has 203 gallons usable divided up into 6 tanks (two mains @ 50 gallons each, two auxes at 31.5 gallons each, two nacelles at 20 gallons each). The nacelles have transfer pumps to pump fuel into the mains. The auxes can only be used by their on-side engine (so in event of an engine failure you don't have access to any fuel in the aux on the dead side). Fuel return from either mains, auxes, or opposite side main (your 3 options per engine) returns to the on-side main. Needless to say, there's some planning involved and contingencies figured out given the over-water nature.
First leg is 1050 nm from MKC to FXE. Then it's just under 1,000 nm from FXE to TISX (St. Croix). Conservatively at 50 GPH first hour (the climb to FL190 is painful on the wallet) and 30 GPH thereafter, it's 6 hours of endurance. Reality is first hour is more like 45 and cruise is about 27 GPH combined, or at least it has been. So we have plenty of fuel diversion options and won't hesitate to use them.
It should be an interesting and fun flight. The basic path (not including fuel stops between St. Croix and Florida):

Travel starts Friday morning, get home Sunday night. Unless we're just too tired on Sunday in which case we'll stop for the night somewhere (Florida sounds nice) and get home Monday.
