when you fly with drop tanks does the engine take the fuel directly from the drop tanks or do they feed in to the main tank as the fuel is used from there

I believe on most planes theres a selector switch to choose which tank to run on, be it internal or external.

They way it is simulted in the game:

Fuel is taken from the drop tanks first. The main internal tank's level does not start to reduce until the drop tank is empty or you jettison it.

If you select, for example 50% fuel plus a drop tank your internal tank will begin at 50% full. The fuel gage will begin counting down from 50% only after you use up the drop tank.

i think in real life that the plane had full internal tanks and the drop tanks kept the tanks they were connected to full until the drop tanks were emtpy and they got dumped

theres a bug it seems after you use up all your drop tank fuel then jettison the tank, the weight is still there. Or maybe its a bug in the drop tank rack itself, seems like it just effects 109s and 190s and jugs

las and p40s seem fine after you jettison the tanks

it would be nice if someone had info on how this actually worked. many planes had fuel tank selectors so i think those were able to drain the drop-tanks without them being mainlined through the main tank. then i it would be interresting to know if any planes of that era could pump fuel between tanks - like in case of a leak http://ubbxforums.ubi.com/infopop/emoticons/icon_smile.gif

when you give your plane 25% fuel and put on an external it pumps fuel into the plane on FB i dont think it did in real life,

Of course it would work that way, so that when you jettison your tanks, you will have the maximum amount of fuel left in your internal tanks.

It would make no sense to have a half full external tank, then jettison half full drop tanks. You'd be wasting a lot of fuel.

But then, in real life, why would you take off with a half full internal tank and drop tanks? Duh.

AFAIK on the Me 109 the fuel from the droptank was "pumped" into the main tank by air pressure, which they drained from the supercharger. There was a transparent tube on the cocpit right (it can be seen in Il-2), in which the pilot could see if the fuel was flowing. I believe then they drained the main tank (which was constantly resupplied from the droptank) directly, but I am not 100% sure in that.

In the game, it makes sense, when you take off with a drop tank, cruise to your operational area, jettison tank and have the less weight to dogfight.
