Hi. so its been 2 days since the issues has come forward especially after latest update, every SID from WADD I Gusti Ngurah Rai airport is bugging and showing DEST EFOB is minus even though all the climb data and fuel prediction was calculated automatically and inputted based on SImBrief. this problem only occur in A350-1000.

 

here i will attach all the flight brief of which i tried to use:
 

WADDRCTP_PDF_1777295074.da1b39f5.pdf WADDVHHH_PDF_1777176433.643b2035.pdf WADDRCTP_PDF_1777198368.bed20d67.pdf

Every single long haul I do in the A35K is the same . Not sure if it’s simbrief or the plane as happens every single time . I’d be happy if I knew how to add a little fuel mid flight without messing the flight up as in 2020 there was a slider button you could simply add a little fuel

Hi,

For the A35K, does this occur while you’re on the ground setting up the aircraft, or does the EFOB simply stop continuously updating as you fly along your flight path?

Thanks!

No it’s fine on the ground . When I return after my 8 hours sleep there’s always a few pounds short of fuel . I just about made it to Hong Kong from Manchester . Tail wind alll the way but maybe I dont know how to calculate wind changes on route .

Sounds like SimBrief may not be calculating enough fuel for your long-haul flights. If possible, try adding an additional 5,000 kg (roughly 10,000 lbs) of fuel on your next long-haul flight and see if that helps.

Thanks!

So I added as extra 10000lb of fuel but still shows as not enough fuel yet 15.9 pounds extra . Or am I not doing this right ?

Hi,

Yes, this number will update once in flight/cruise.

Thanks!
