Ok, what if you accelerate upwards and then the control system suddenly decides it's high enough- it turns down the engines for a moment, air drag now means you have negative g's in the direction you were moving in. The fuel will end up at the top of the tank, and your engines will suck gas.Sloshing? Slosh will be a PITA to model, yes. And the purist will want to include it. But...
Where will the slosh come from? Isn't all of the acceleration along the vertical axis of the vehicle? Seems to me the only way you could get slosh is a) if an engine quit, b) if you get hit by a strong gust of wind (POGO will have a pretty high cross sectional density, so will not be greatly affected by wind), or c) if you're flying horizontally at speed and you suddenly pitch back to level. If a) happens, you won't care about slosh. To prevent b), don't fly in strong gusts. To prevent c), don't do that.
Yes?
The professionals certainly stuff this up fairly often. Apollo had TV cameras in the LOX tank because they were paranoid about it for example.
