So my question is this, is a UAT really that much better than using a plain header tank? I know the purpose of a UAT is to eliminate air bubbles in the fuel tank, but I don't see how air bubbles could form in a header tank that is full of fuel the entire flight. Also turbines have very low vibration so that would also make it harder for air bubbles to form as opposed to a gas engine. Basically would just like to here some opinions.
