Hi guys,
This has been bugging me since day one and I would like to try and get it sorted once and for all. Simply put, the fuel consumption (and/or FMC calculation) is all over the place and way off what any planning tool churns out. I use mainly Simbrief since that is the fastest way to load a flightplan into the FMC but regardless of what 748 option I use (Default, Salty, Working Title), I always start off with too little calculated fuel and arrive with way too much. This only gets worse on long haul flights.
Take for example a recent flight from Manchester to Singapore. If I loaded the exact amount of fuel Simbrief tells me to, including reserves, the FMC tells me I would be short 25 tons at the destination. If I ignore that and depart anyway, I’ll arrive with over 100 tons of FOB.
I’ve gone to the extent of deleting the entire 747 folder and forcing MSFS to redownload/reinstall that aircraft just to make sure the fuel consumption values are untouched and honestly as a casual simmer I couldn’t be ■■■■■ whether or not it perfectly matches up in real life. I just want it to be consistent both during flight planning and actual operations. Currently loading up fuel just feels like a crapshoot.
Can anyone advise what values I should tweak the config so that it matches up to at least 1 of the Simbrief airframes please? Or any other solution to get some semblance of proper operations, really.
Thank you.
