So I’m currently flying LHR-SCL in a B787-9 with 89.250Kg of fuel (that was at takeoff) and my ETE To Destination is showing red. So I need to know if 89,250Kg of fuel will last 16 hours. If someone could load IF and check I would greatly appreciate that
It will. Usually during climb, the numbers go down as you use more power and fuel. At cruise you should be good. If it’s still in red, slow down and climb at a reasonable rate.
If your N1 is around 90-100% you are too heavy for the altitude. I suggest you go lower until you have burnt off some fuel.
Speed should be M 0.85
Safe flight :)
On such long flights this can be the case. As you get lighter the fuel flow decreases and hence the time the fuel lasts is calculated constantly by IF.
My last long-haul started with a red fuel indication (as far as I remember) and I landed with +1h of fuel.
Okay I think you are in a jet stream in the moment wich makes you slower but it should be good because if you look at windy.com for FL340 it says that you will be out there soon
