I searched through before posting this and have not seen any similar topics so I thought I would bring it up here and see if anyone has noticed the same issue. It was hard to put in to words but I feel I have finally zeroed in on it. I will include some screenshots if I am able to upload them.
After spawning in my A380 and adding fuel, I determined that once my aircraft would reach MLW, I would still have 137,xxx lbs of fuel left. 14 hours into my flight I was descending and checked my weights. I still had 125,000 lbs of fuel left (which in theory should mean I was under MLW, but I wasn’t) It indicated to me I would need to dump 77,000 lbs of fuel to be under MLW. After using the fuel dump and allowing it to stop on its own at MLW, it left me with only 8,000 lbs of fuel left.
What went wrong?
(I’ll attempt to upload my screenshots in the replies)
