Forever I flew the Captain Sim Lockheed C130 Hercules (purchased during the January 2017 sale) accepting that engines would start quitting below certain fuel levels. Instead of solving the root issue of not having enough non fuel starved engines to take off, I would simply start my flight at altitude and speed and hope I had enough working engines to sustain flight.
Today I finally decided to put the vacuum behind my eyes to work and learn me some fuel crossfeed. It is ridiculously intuitive. Still, I’m feeling quite proud of myself for figuring it out without looking it up.
