Okay, so water in the fuel tanks is bad. But you still refuel in the rain, right? So then what do you do? Wait a while and drain the tanks? Go to extreme measures to try to keep the water out? Thanks!*edit* Oooh...another question, too...Let's say you always fuel up after you land so the tanks are always full. What do you do if the next time you're getting ready to fly you realize that you'll be too heavy if you take full fuel? Do you just go up and burn off as much as you need, or what (assuming you can't otherwise lighten the load)?Thanks again! :-)

Refueling while raining happens all the time you just have to be careful. I

>Also Jet fuel has a considerable amount of water already in it >anyways so it

Hi Terry,Jet fuels are a blended mixture of what is called heavy distillates that result in a relative density that is very close to water, closer than Avgas and because of this jet fuel holds water in suspension for longer periods of time making it far more difficult to remove or for that matter even detect at all. As I recall there are two types of water contamination in Jet fuel, entrained and dissolved. Jet fuel contains a good bit of dissolved water, which finds it

Thanks for the info. It's funny to have hauled all that stuff and know so little about its chemistry. Ahh, the driver's life.As to getting water in the tanks when refueling, as I remember from my flying days back in Idaho, we never really worried much about it. In the winter, the fuel boys would scrape off the snow and gas her up and in the summer it never rains there anyway so it wasn't an issue. Out here in Nawth Kackalcky they probably wait for the thundershowers to pass before fueling.

No problem,I

Entrained and dissolved would be the same. And may or may not be visible."Water Slugs" is the other type. Very visable and drops to bottom of fuel sample jar like a rock.Particle contamination is where it takes longer in jet fuels to settle than AVGAS.
