Can someone here give me a little guidance? I intend to take a B747-8 flight that will be around13 hours. I’m not sure how to manage the fuel for it though because I’m not very familiar with it and have never actually flown on it. Thanks!
the 747 is an ancient plane, so the fuel burn is quite off. I would recommend using a flight planning app like Fptoif and adding a heavy amount to the recommended fuel.
Actually, you are so wrong. The estimated fly time for the fuel is about 1.30-2.30 hours wrong, but the estimated fuel weigh (what Simbrief usually calculates for me) is not so wrong.
What I tell you now sounds maybe weird but, but when you set flaps 10 on your Cruiselevel. You will reduce your Fuel Flow and improve/ increase your Range . It will be nearly 1:1 as shown in the menu :)
So your flight will be 13 hours ? Add fuel for 15:30 and you should be fine :)
