Attn: Beechjet pilots (fuel temps)

[Machdog1]

My company has 4 Hawker 400s (beechjets) and we do a lot of NY's to south florida during the winter time and I have noticed that the fuel temperatures have been bottoming out at the -40 limit a lot lately on these 2 plus hour flights. Is this happening to a lot to other guys out there because I have to lose like 10,000ft just to stay at that current temperature, and of course that is destroying my fuel burn. Just looking for any advise out there about what other people are doing. Man I wish we had fuel heaters on that thing.

Thanks

I've seen -40 several times on long trips. Usually it just seems to stay there and not get any colder.

I've turned on the wing heat in the past, rather than descend.

At 51,000 feet on a flight from Kauai to Singapore, in an experimental GV before the fuel heating system was certified, I had the wing fuel temp hit -37 C. We ended up dead-sticking the jet into Chiangi from around 200 nm out.

That was before Global Warming... when TIME was worried about a "New Ice Age" on their cover. Surprised they didn't cite this incident as proof?

Given the beechjets recent history, I would pay very close attention to the following.

1) Fuel temps, If you have to get down for some warmer air, do it, even if it means a fuel stop.

2) Engine heat on anytime your in temps below 10C, and in or near visable moisture. Includeing rapid decents into humid or tropical air.

3) Mointor the fuel truck and line guys to make sure your getiing the prist you need. Several times, I have been told "yeah were premix" only to discover that it was injected. And not turned "ON" or....the injector sys wasn't even working.

Good luck !
