Amazing. Must have some extra fuel on board.

He's right in the middle given the winds. I trust he does have extra fuel. No turning back.

I relayed position reports for a King Air this summer while I was flying the 737 to Hawaii. At the time I thought that was pretty cool. Then I remembered man 5.5 hrs in the 737 is a long time making the hop to HNL. Can’t imagine how 10hrs or better would suck by myself in a KA.

Let’s hope so!

Showing 9 hours enroute. Would be interesting to see how this company got the extra fuel.

The only extra fuel tank in a PC12 I have ever seen was Amelia Earhart’s when she flew around the world with Shane. Pilatus engineers designed and installed it. 200 gallons I think.

How many gallons per hour does the PC - 12 drink?

I will obviously defer to Jason but if I were flying over an ocean like that I would figure at least 70 gallons per hour. For a 10-hour flight I would want to have at least double the 400-gallon capacity that is standard in the Pilatus.

A nice easy rule of thumb for the -12 is 600lbs the first hour, 500lbs the second hour, and 400lbs each hour after.

I would one of those inside the pressure vessel would make the install more complicated.

With a bladder inside the pressure cabin, would one just wait for space in the mains to receive it, and let the pressure (and gravity) push it there when allowed (valved open)? Is there a fundamental difference from gravity, with a cabin tank in a low-wing airplane?

I dunno about fuel systems for turbines. I doubt the difference between cabin-pressure fuel and ambient is a challenge for any such system, unless you think the cabin-pressure will push fuel out of the ambient tank vents (same as gravity).

For a positive displacement fuel pump, I don't think the 6 or so PSI head pressure would make a difference. Turtlepacs are installed in lots of pressurized aircraft. I'm sure it a no brainer at this point.

You are correct.
A friend of mine did the record flight New York to Paris in a TBM 930 this summer. 300 extra gallons in the cabin, no pumps all pressure fed to the main tanks by the cabin differential pressure.

A friend of mine, Josh Marvel, has flown around the world three times now in a stock PC 12.

His co-captain mentioned that they could make a Hawaii to mainland flight in a stock PC-12 eastbound when winds were favorable on a fair number of days.

Did they do it? I could easily do it in the Merlin but getting there would generally mean going the long way around
