Decided to post here rather than in the WTR Forum since hoping this might be a good collaboration opportunity. 
  
We are trying to better understand the current logic of fuel consumption and potential for air-to-air refueling (although a long shot). 
So first question, in debug mode does the "Fuel Weight" variable as displayed actually represent the remaining fuel?   
There must be a logic check given against a certain memory register, especially because there is a trigger that signals the Bingo Fuel call (I think we narrowed that down to 2.2 if I recall). 
So therefore, theoretically it could be something like:  If FuelWeight<=2.2 then...messagesystem Bingo Fuel. 
  
Does anyone have any more insight or info to share on this?  Would under the Gen2 series, would we still need a 2nd "fake" engine to reverse fuel flow? 
What about creating, just for test purposes, an engine that only runs in reverse so to speak?  If we were to collaborate on that, then we could assess from the debug what values are changing.  After that of course, I would think someone on our team could dig deeper through the memory registers but I realized we don't have all the base knowledge to start.  Interestingly enough we were able to make the fuel gauge "go up" but realized that was just the draw call on how to paint the needle.  So the hunt continues...
