Heya!! Dunno if htis is any help, but I discovered the Simbrief fuel consumption seemed based on the normal engines and not the LEAP engines, which are 30% more efficient. Therre is a setting on the Aircraft page in Simbrief where you can set a fuel factor M30 - ie minus 30% I have been using that for months and my predicted landing weights have been very accurate
I found this accurate until yesterday… and now today, I find my fuel is about 30% short… I landed at Bali on fumes (400kg) , and why I am poking around the forum on this. I did the FBW update yesterday and note the little LEAP icon does not appear on the FBW install app
I checked weights and wind in the FP, even the Cost Index… all seemed spot on. Something here has changed
edit: checking the FBW team post above, there is an updated simbrief profile for the A320 with new weights. Perhaps the fuel consumption was update and I no longer need the reduced fuel factor. will fly and see… I don’t think the passengers need to know… lol
