I really haven't been able to find a concise answer for this in the AFM so far, so I figured I'd ask here. What exactly is the proper way to load the fuel? I found one document stating that the main tank must always be filled first, then the outers, then the tips. However, most videos I've watched even for short flights show the real aircraft with quite a lot of fuel in the tips. Is it absolutely mandatory for them to at least have some fuel in them?
Say for example I used the Simbrief profile linked in another thread here and it calculates 1300 lbs of fuel for the flight that I'm planning. By the procedure I mentioned, I would fill the main tank to the brim and then split whatever is left into the outers, and ending up leaving the tips empty. Is this correct? The default X-Plane slider instead goes in reverse, filling the tips first, then the outers, and finally the center, and I have a feeling that isn't exactly right, but I can always be wrong.
Just looking for some clarity.
