Can anyone tell me how to switch tanks??

Aux tank in 190 is behind the AFT tank, and the AFT tank already burns before the FWD tank.

In a 190 there is no need to use manual burn* because it already burns in this order: AUX, AFT, FWD.



*The only time I do this is when I have a DT, I'll sometimes burn some/all of the AUX so that if/when I drop the DT early I can dogfight better, then I switch back to auto burn and drain the DT as normal.

where is the 190's aux tank located? I've always assumed that the tanks burn off in the most CoG/polar interia efficient way when on auto.

The 190s especially benefit from optimal fuel tank sequence, but other planes that could also benefit from it (e.g. the Mossie) still have the auto set to default sequence.
